A respected Italian art scholar claims to
have identified a previously unknown painting by Michelangelo at the
University of Oxford.
Antonio Forcellino, a veteran Italian conservator, made international
headlines last month when he backed a wealthy New York family's claim that a
painting they had stored behind their sofa was by the Renaissance master.
Now Forcellino says new research techniques applied to a piece owned by
Campion Hall, an institution which allows religious scholars to study at
Oxford, has revealed it to be an authentic Michelangelo.
Crucifixion With The Madonna, St John And Two Mourning Angels was believed to
have been a work by Marcello Venusti, one of Michelangelo's contemporaries.
"You can immediately see the difference between this work and that of
Venusti," said Mr Forcellino, who used infra-red techniques to study
layers beneath the finished painting. He writes in his new book, The Lost
Michelangelos, that "no one but Michelangelo could have painted such a
masterpiece".
While most of the headlines accompanying Mr Forcellino's book have focused on
his discovery in the US, none have mentioned his British find.
"The figure of Christ was in a wholly different league... the modelling
was stronger, and the painting and facial expression had a clarity that
created the impression of an artist of much greater standing," writes
Mr Forcellino.
The hall bought the painting at a Sotheby's auction in the 1930s. According to
the hall's master, Brendan Callaghan, scholarship until now had attributed
the work to Venusti. Mr Callaghan said: "If true, the painting would go
from being one member of our fine collection to the most exciting part of
it. It could not remain within our four walls." The work is being cared
for by Oxford's Ashmolean Museum of Art and Archaeology.
Mr Forcellino claimed London's National Gallery continued to attribute the
work to Venusti "out of embarrassment" that they had not
identified it. A National Gallery spokeswoman said the gallery did not
comment on works not held in its collection.
The Michelangelo painting of Jesus and Mary identified in New York had been
placed behind a sofa after being knocked off the wall by a tennis ball.
The Experts
Antonio Forcellino is one of the world's leading authorities on
Michelangelo and an expert art historian and restorer. He has been involved
in the restoration of numerous masterpieces, including Michelangelo's Moses.
In 2009 he wrote a biography on the artist and his work – Michelangelo: A
Tormented Life retraces the master's journey from Rome to Florence, explores
his changing religious views and examines the complicated politics of
patronage in Renaissance Italy. He has also written The Lost Michelangelos,
which used historical research, restoration and radiographic analysis to
trace two paintings to Michelangelo's studio.
Painting is the practice of applying paint, pigment, color or other mediumto a surface (support base). In art, the term describes both the act and the result, which is called a painting.
A portion of the history of painting in both Eastern and Western art is dominated by spiritual motifs and ideas; examples of this kind of painting range from artwork depicting mythological figures on pottery to Biblical scenes rendered on the interior walls and ceiling of The Sistine Chapel, to scenes from the life of Buddha or other scenes of eastern religious origin.
"The boundary of things in the second plane will not be discerned like those in the first. Therefore, painter, do not produce boundaries between the first and the second, because the boundary of one object and another is of the nature of a mathematical line but not an actual line, in that the boundary of one colour is the start of another colour and is not to be accorded the status of an actual line, because nothing intervenes between the boundary of one colour which is placed against another. Therefore, painter, do not make the boundaries pronounced at a distance."
What enables painting is the perception and representation of intensity. Every point in space has different intensity, which can be represented in painting by black and white and all the gray shades between.
In practice, painters can articulate shapes by juxtaposing surfaces of different intensity; by using just color (of the same intensity) one can only represent symbolic shapes. Thus, the basic means of painting are distinct from ideological means, such as geometrical figures, various points of view and organization (perspective), and symbols. For example, a painter perceives that a particular white wall has different intensity at each point, due to shades and reflections from nearby objects, but ideally, a white wall is still a white wall in pitch darkness. In technical drawing, thickness of line is also ideal, demarcating ideal outlines of an object within a perceptual frame different from the one used by painters.
Color and tone are the essence of painting as pitch and rhythm are of music. Color is highly subjective, but has observable psychological effects, although these can differ from one culture to the next. Black is associated with mourning in the West, but in the East, white is. Some painters, theoreticians, writers and scientists, including Goethe, Kandinsky, Newton, have written their own color theory. Moreover the use of language is only a generalisation for a color equivalent.
The word "red", for example, can cover a wide range of variations on the pure red of the visible spectrum of light. There is not a formalized register of different colors in the way that there is agreement on different notes in music, such as C in music.
For a painter, color is not simply divided into basic and derived (complementary or mixed) colors (like, red, blue, green, brown, etc.). Painters deal practically with pigments, so "blue" for a painter can be any of the blues: phtalocyan, Paris blue, indigo, cobalt, ultramarine, and so on. Psychological, symbolical meanings of color are not strictly speaking means of painting. Colors only add to the potential, derived context of meanings, and because of this the perception of a painting is highly subjective. The analogy with music is quite clear—sound in music (like "C") is analogous to light in painting, "shades" to dynamics, and coloration is to painting as specific timbre of musical instruments to music—though these do not necessarily form a melody, but can add different contexts to it.
Rhythm is important in painting as well as in music. Rhythm is basically a pause incorporated into a body (sequence). This pause allows creative force to intervene and add new creations—form, melody, coloration. The distribution of form, or any kind of information is of crucial importance in the given work of art and it directly affects the esthetical value of that work. This is because the esthetical value is functionality dependent, i.e. the freedom (of movement) of perception is perceived as beauty. Free flow of energy, in art as well as in other forms of "techne", directly contributes to the esthetical value.
Modern artists have extended the practice of painting considerably to include, for example, collage, which began with Cubism and is not painting in the strict sense. Some modern painters incorporate different materials such as sand, cement, straw or wood for their texture. Examples of this are the works of Jean Dubuffet and Anselm Kiefer. (There is a growing community of artists who use computers to paint color onto a digital canvas using programs such as Adobe Photoshop, Corel Painter, and many others. These images can be printed onto traditional canvas if required.)
In 1829, the first photograph was produced. From the mid to late 19th century, photographic processes improved and, as it became more widespread, painting lost much of its historic purpose to provide an accurate record of the observable world. There began a series of art movements into the 20th century where the Renaissance view of the world was steadily eroded, through Impressionism, Post-Impressionism, Fauvism, Expressionism, Cubism and Dadaism. Eastern and African painting, however, continued a long history of stylization and did not undergo an equivalent transformation at the same time.
Modern and Contemporary Art has moved away from the historic value of craft and documentation in favour of concept; this led some to say in the 1960s that painting, as a serious art form, is dead. This has not deterred the majority of living painters from continuing to practice painting either as whole or part of their work.
The vitality and versatility of painting in the 21st century belies the premature declarations of its demise. In an epoch characterized by the idea of pluralism, there is no consensus as to a representative style of the age. Important works of art continue to be made in a wide variety of styles and aesthetic temperaments, the marketplace being left to judge merit.
The oldest known paintings are at the Grotte Chauvet in France, claimed by some historians to be about 32,000 years old. They are engraved and painted using red ochre and black pigment and show horses, rhinoceros, lions, buffalo, mammoth or humans often hunting.
However the earliest evidence of painting has been discovered in two rock-shelters in Arnhem Land, in northern Australia. In the lowest layer of material at these sites there are used pieces of ochre estimated to be 60,000 years old. Archaeologists have also found a fragment of rock painting preserved in a limestone rock-shelter in the Kimberley region of North-Western Australia, that is dated 40 000 years old. There are examples of cave paintings all over the world—in France, Spain, Portugal, China, Australia, India etc.
In Western cultures oil painting and watercolor painting are the best known media, with rich and complex traditions in style and subject matter. In the East, ink and color ink historically predominated the choice of media with equally rich and complex traditions.
Aesthetics is the study of art and beauty; it was an important issue for such 18th and 19th century philosophers as Kant or Hegel. Classical philosophers like Plato and Aristotle also theorized about art and painting in particular; Plato disregarded painters (as well as sculptors) in his philosophical system; he maintained that painting cannot depict the truth—it is a copy of reality (a shadow of the world of ideas) and is nothing but a craft, similar to shoemaking or iron casting.
By the time of Leonardo painting had become a closer representation of the truth than painting was in Ancient Greece. Leonardo da Vinci, on the contrary, said that "Pittura est cousa mentale" (painting is a thing of the mind). Kant distinguished between Beauty and the Sublime, in terms that clearly gave priority to the former. Although he did not refer particularly to painting, this concept was taken up by painters such as Turner and Caspar David Friedrich.
Hegel recognized the failure of attaining a universal concept of beauty and in his aesthetic essay wrote that Painting is one of the three "romantic" arts, along with Poetry and Music for its symbolic, highly intellectual purpose. Painters who have written theoretical works on painting include Kandinsky and Paul Klee. Kandinsky in his essay maintains that painting has a spiritual value, and he attaches primary colors to essential feelings or concepts, something that Goethe and other writers had already tried to do.
Iconography is the study of the content of paintings, rather than their style. Erwin Panofsky and other art historians first seek to understand the things depicted, then their meaning for the viewer at the time, and then analyse their wider cultural, religious, and social meaning.
In 1890, the Parisian painter Maurice Denis famously asserted: "Remember that a painting – before being a warhorse, a naked woman or some story or other – is essentially a flat surface covered with colors assembled in a certain order."Thus, many twentieth century developments in painting, such as Cubism, were reflections on the means of painting rather than on the external world, nature, which had previously been its core subject.
Recent contributions to thinking about painting has been offered by the painter and writer Julian Bell. In his book What is Painting?, Bell discusses the development, through history, of the notion that paintings can express feelings and ideas. In Mirror of The World Bell writes:
‘A work of art seeks to hold your attention and keep it fixed: a history of art urges it onwards, bulldozing a highway through the homes of the imagination.’
Art world swoons over Romania's homeless genius
63-year-old former tramp celebrated for collages made during Ceausescu regime
Ion Barladeanu lived in the garbage room of a block of flats until mid-2008, when his work was discovered by the art world
The guests were chic, the bordeaux was sipped with elegant
restraint and the hostess was suitably glamorous in a canary yellow
cocktail dress. To an outside observer who made it past the soirée privée sign
on the door of the Anne de Villepoix gallery on Thursday night, it
would have seemed the quintessential Parisian art viewing.
Yet that would been leaving one crucial factor out of the
equation: the man whose creations the crowd had come to see. In his
black cowboy hat and pressed white collar, Ion Barladeanu looked every
inch the established artist as he showed guests around the exhibition.
But until 2007 no one had ever seen his work, and until mid-2008 he was
living in the rubbish tip of a Bucharest tower block.
Today, in the culmination of a dream for a Romanian who grew up
adoring Gallic film stars and treasures a miniature Eiffel Tower he
once found in a bin, Barladeanu will see his first French exhibition
open to the general public.
Dozens of collages he created from scraps of discarded magazines
during and after the Communist regime of Nicolae Ceausescu are on sale
for more than €1,000 (£895) each. They are being hailed as politically
brave and culturally irreverent.
For the 63-year-old artist, the journey from the streets of
Bucharest to the galleries of Europe has finally granted him
recognition. "I feel as if I have been born again," he said, as some of
France's leading collectors and curators jostled for position to see
his collages. "Now I feel like a prince. A pauper can become a prince.
But he can go back to being a pauper too."
That Barladeanu should remain stoical in the face of his sudden
stardom is perhaps unsurprising. In 1989, he was one of many Romanians
whose delight at Ceausescu's fall turned to frustration when work dried
up. For the next 20 years, he lived on a mattress amid sacks of rubbish
in the garbage room of a block of flats, earning money from odd jobs
and making collages in secret.
"This was a man living on the border of society and still
retaining a sense of self," said Alexander Nanau, a Bucharest-based
director who has filmed a documentary on Barledeanu for HBO Central
Europe. "He was lazy in a good way because that was the only way he
could make his art – by hiding from a society he didn't want to get
involved with."
Eventually, in 2007, Barladeanu showed his collages to an artist who
happened to also be combing through the garbage. Amazed, the artist
called a gallery owner. From that moment on, Barladeanu's days in the
dump were numbered. "I instantly thought it was something very
important, at least for Romania,"
said Dan Popescu, whose H'Art gallery specialises in young,
little-known contemporary artists. With badly decaying teeth and a face
ravaged by over 60 Romanian winters, Barledeanu was not young, and his
anonymity would not last long.
Within six months, he was given his first exhibition, a flat of his own and a brand new set of dentures (false teeth).
In 2009, he made his first trip overseas and showed some collages at
the Basel art fair. This week, he jetted into Paris, saw the Eiffel
Tower for real and had lunch with the actor and fan Angelina Jolie, in
town for her next movie.
Barledeanu describes himself as a "director" of his own films and
considers each collage to be a movie in itself. While many are
light-hearted, others are darker, infused with black humour and often
focusing on the man he calls his "greatest fear". "I knew that if he
knew about my work Ceausescu would not sleep in peace in his grave," he
said. "If people had found out about my work they could have chopped my
head off … But this is my revenge."
Many of the most explosive collages were made after 1989, but
those that were made during the regime have already interested
collectors. Antoine de Galbert of La Maison Rouge art foundation said
he appreciated "the risk involved" in Barledeanu's work, while Jérôme
Neutres of the Grand Palais said the artist's background lent the
collages a unique appeal. "Of course there is a fairytale aspect to his
work, but that is not important to me. What I like is that he has been
spared the usual artistic circles and his work is refreshing as a
result," he said.
Whatever the world thinks, Barladeanu says he will carry on
working regardless. "It's like eating pie or sandwiches. It fulfils
me," he said in his fast-paced Romanian slang. "If I were reincarnated
in another life I would still be making collages, and if I could take
them to the moon I would."

Painting styles
'Style' is used in two senses: It can refer to the distinctive visual elements, techniques and methods that typify an individual artist's work. It can also refer to the movement or school that an artist is associated with. This can stem from an actual group that the artist was consciously involved with or it can be a category in which art historians have placed the painter. The word 'style' in the latter sense has fallen out of favor in academic discussions about contemporary painting, though it continues to be used in popular contexts. Such movements or classifications include the following :

Sculpture is three-dimensionalartwork created by shaping or combining hard, plastic material, sound, text, light, commonly stone (either rock or marble), metal, glass, or wood. Some sculptures are created directly by finding or carving; others are assembled, built together and fired, welded, molded, or cast. Sculptures are often painted.
Because sculpture involves the use of materials that can be moulded or modulated, it is considered one of the plastic arts. The majority of public art is sculpture. Many sculptures together in a garden setting may be referred to as a sculpture garden.
Types of sculpture
Some common forms of sculpture are:
Free-standing sculpture, sculpture that is surrounded on all sides, except the base, by space. It is also known as sculpture "in the round", and is meant to be viewed from any angle.
Sculptors have generally sought to produce works of art that are as permanent as possible, working in durable and frequently expensive materials such as bronze and stone: marble, limestone, porphyry, and granite. More rarely, precious materials such as gold, silver, jade, and ivory were used for chryselephantine works. More common and less expensive materials were used for sculpture for wider consumption, including glass, hardwoods (such as oak, box/boxwood, and lime/linden); terracotta and other ceramics, and cast metals such as pewter and zinc (spelter).
Sculptures are often painted, but commonly lose their paint to time, or restorers. Many different painting techniques have been used in making sculpture, including tempera, [oil painting], gilding, house paint, aerosol, enamel and sandblasting.[
Many sculptors seek new ways and materials to make art. Jim Gary used stained glass and automobile parts, tools, machine parts, and hardware. One of Pablo Picasso's most famous sculptures included bicycle parts. Alexander Calder and other modernists made spectacular use of painted steel. Since the 1960s, acrylics and other plastics have been used as well. Andy Goldsworthy makes his unusually ephemeral sculptures from almost entirely natural materials in natural settings. Some sculpture, such as ice sculpture, sand sculpture, and gas sculpture, is deliberately short-lived.
Sculptors often build small preliminary works called maquettes of ephemeral materials such as plaster of Paris, wax, clay, or plasticine, as Alfred Gilbert did for 'Eros' at Piccadilly Circus, London. In Retroarchaeology, these materials are generally the end product.
Many different forms of sculpture were used in Asia, with many pieces being religious art based around Hinduism and Buddhism (Buddhist art) and greco-Buddhist art. A great deal of Cambodian Hindu sculpture is preserved at Angkor, however organized looting has had a heavy impact on many sites around the country. In Thailand, sculpture was almost exclusively of Buddha images. Many Thai sculptures or temples are gilded, and on occasion enriched with inlays.
The first known sculptures are from the Indus Valley civilization (3300–1700 BC), found in sites at Mohenjo-daro and Harappa in modern-day Pakistan. These are among the earliest known instances of sculpture in the world.
Later, as Hinduism, Buddhism, and Jainism developed further, India produced bronzes and stone carvings of great intricacy, such as the famous temple carvings which adorn various Hindu, Jain and Buddhist shrines. Some of these, such as the cave temples of Ellora and Ajanta, are examples of Indian rock-cut architecture, perhaps the largest and most ambitious sculptural schemes in the world.
During the 2nd to 1st century BC in northern India, in what is now southern Afghanistan and northern Pakistan, sculptures became more anatomically realistic, often representing episodes of the life and teachings of Gautama Buddha. Although India had a long sculptural tradition and a mastery of rich iconography, the Buddha was never represented in human form before this time, but only through symbols such as the stupa. This alteration in style may have occurred because Gandharan Buddhist sculpture in ancient Afghanistan acquired Greek and Persian influence. Artistically, the Gandharan school of sculpture is characterized by wavy hair, drapery covering both shoulders, shoes and sandals, and acanthusleaf decorations, among other things.
The pink sandstone sculptures of Mathura evolved during the Gupta Empire period (4th-6th century AD) to reach a very high fineness of execution and delicacy in the modeling. Gupta period art would later influence Chinese styles during the Sui dynasty, and the artistic styles across the rest of east Asia.
Newer sculptures in Afghanistan, in stucco, schist or clay, display very strong blending of Indian post-Gupta mannerism and Classical influence. The celebrated bronzes of the Chola dynasty (c. 850-1250) from south India are of particular note; the iconic figure of Nataraja being the classic example. The traditions of Indian sculpture continue into the 20th and 21st centuries with for instance, the granite carving of Mahabalipuram derived from the Pallava dynasty. Contemporary Indian sculpture is typically polymorphous but includes celebrated figures such as Dhruva Mistry.

Artifacts from China date back as early as 10,000 BC and skilled Chinese artisans had been active very early in history, but the bulk of what is displayed as sculpture comes from a few select historical periods.
The first period of interest has been the Western Zhou Dynasty (1050-771 BC), from which come a variety of intricate cast bronze vessels.
The next period of interest was the Han Dynasty (206 BC-220 AD), beginning with the spectacular Terracotta Army assembled for the tomb of Qin Shi Huang, the first emperor of the important but short-lived Qin Dynasty that preceded the Han. Tombs excavated from the Han period have revealed many figures found to be vigorous, direct, and appealing 2000 years later.
The period now considered to be China's golden age is the Tang Dynasty, coinciding with what in Europe is sometimes called the Dark Ages). Decorative figures like those shown below became very popular in 20th century Euro-American culture, and were made available in bulk, as warlords in the Chinese civil wars exported them to raise cash. Considered especially desirable, and even profound, was the Buddhist sculpture, often monumental, begun in the Sui Dynasty, inspired by the Indian art of the Gupta period, and many are considered treasures of world art.
Following the Tang, Western interest in Chinese artifacts drops off dramatically, except for what might be considered as ornamental furnishings, and especially objects in jade.
Pottery from many periods has been collected, and again the Tang period stands out apart for its free, easy feeling. Chinese sculpture has no nudes—other perhaps than figures made for medical training or practice—and very little portraiture compared with the European tradition. One place where sculptural portraiture was pursued, however, was in the monasteries.
Almost nothing, other than jewelry, jade, or pottery is collected by art museums after the Ming Dynasty ended in the late 17th century—and absolutely nothing has yet been recognized as sculpture from the tumultuous 20th century, although there was a school of Soviet-influenced social realist sculpture in the early decades of the Communist regime, and as the century turned, Chinese craftsmen began to dominate commercial sculpture genres (the collector plates, figurines, toys, etc) and avant garde Chinese artists began to participate in the Euro-American enterprise of contemporary art.

Countless paints and sculpture were made, often under governmental sponsorship. Most Japanese sculpture is associated with religion, and the medium' use declined with the lessening importance of traditional Buddhism.
During the Kofun period of the third century, clay sculptures called haniwa were erected outside tombs. Inside the Kondo at Hōryū-ji is a Shaka Trinity (623), the historical Buddha flanked by two bodhisattvas and also the Guardian Kings of the Four Directions. The wooden image ( 9th c.) of Shakyamuni, the "historic" Buddha, enshrined in a secondary building at the Murō-ji, is typical of the early Heian sculpture, with its ponderous body, covered by thick drapery folds carved in the hompa-shiki (rolling-wave) style, and its austere, withdrawn facial expression. The Kei school of sculptors, particularly Unkei, created a new, more realistic style of sculpture.
African art has an emphasis on Sculpture - African artists tend to favor three-dimensional artworks over two-dimensional works.
African sculptures
The style, key aesthetic characteristics, materials, and techniques used in the creation of a piece of sculpture reflects the region from which it originates. Sculptures often have unique functions that vary widely from one geographical region to the next.
In West Africa, the earliest known sculptures are from the Nok culture of Nigeria, which dates around 500 BC. The figures of West African sculptures typically have elongated bodies, angular shapes, and facial features that represent an ideal rather than an individual.
These figures are used in religious rituals. They are made to have surfaces that are often coated with materials placed on them for ceremonial offerings. In contrast to these sculptures of West Africa are the ones of Mande-speaking peoples of the same region. The Mande pieces are made of wood and have broad, flat surfaces. Their arms and legs are shaped like cylinders.
In Central Africa, however, the main distinguishing characteristics include heart-shaped faces that are curved inward and display patterns of circles and dots. Although some groups prefer more geometric and angular facial forms, not all pieces are exactly the same, nor are they made of the same material. The primary material is wood, though ivory, bone, stone, clay, and metal are also used. The Central African region has very striking styles that are very easy to identify, making regional identification very easy.
Eastern Africans are not known for their sculpture, but, one type that is created in this area is pole sculptures, which are poles carved in human shapes, decorated with geometric forms, while the tops are carved with figures of animals, people, and various objects. These poles are, then, placed next to graves and are associated with death and the ancestral world.
Southern Africa’s oldest known clay figures date from 400 to 600 A.D. and have cylindrical heads. These clay figures have a mixture of human and animal features. Other than clay figures, there are also wooden headrests that were buried with their owners. The headrests had styles ranging from geometric shapes to animal figures. Each region had a unique style and meaning to their sculptures. The type of material and purpose for creating sculpture in Africa reflect the region from which the pieces are created.
The ancient art of Egyptian sculpture evolved to represent the ancient Egyptian gods, and Pharaohs, the divine kings and queens, in physical form. Very strict conventions were followed while crafting statues: male statues were darker than the female ones; in seated statues, hands were required to be placed on knees and specific rules governed appearance of every Egyptian god.
Artistic works were ranked according to exact compliance with all the conventions, and the conventions were followed so strictly that over three thousand years, very little changed in the appearance of statues except during a brief period during the rule of Akhenaten and Nefertiti when naturalistic portrayal was encouraged.
Sculpture in what is now Latin America developed in two separate and distinct areas, Mesoamerica in the north and Peru in the south. In both areas, sculpture was initially of stone, and later of terracotta and metal as the civilizations in these areas became more technologically proficient.
The Mesoamerican region produced more monumental sculpture, from the massive block-like works of the Olmec and Toltec cultures, to the superb low reliefs that characterize the Mayan and Aztec cultures. In the Andean region, sculptures were typically small, but often show superb skill.
In North America, wood was sculpted for totem poles, masks, utensils, War canoes and a variety of other uses, with distinct variation between different cultures and regions. The most developed styles are those of the Pacific Northwest Coast, where a group of elaborate and highly-stylized formal styles developed forming the basis of a vibrant tradition that is in a renaissance today (see Bill Reid) and has moved into other mediums such as silver, gold and modern materials. The introduction of metal tools introduced new carving techniques, including the use of a black type of argillite, also called black slate, which is exclusive for use by artists of the Haida people.

In addition to the famous totem poles, painted and carved house fronts were complemented by carved posts inside and out, as well as mortuary figures and other items. Among the Inuit of the far north, traditional carving styles in ivory and soapstone have been expanded through the use of modern power tools into new directions for Inuit culture which, like the art of the Northwest Coast, is highly prized by art collectors for its plastic forms and innovative interpretation of figure and story.
The arrival of European Catholic culture readily adapted local skills to the prevailing Baroque style, producing enormously elaborate retablos and other mostly church sculptures in a variety of hybrid styles.
The most famous of such examples in Canada is the altar area of the Notre Dame Basilica in Montreal, Quebec, which was carved by peasant habitant labourers. Later, artists trained in the Western academic tradition followed European styles until in the late nineteenth century they began to draw again on indigenous influences, notably in the Mexican baroque grotesque style known as Churrigueresque. Aboriginal peoples also adapted church sculpture in variations on Carpenter Gothic; one famous example is the Church of the Holy Cross in Skookumchuck Hot Springs, British Columbia.
The history of sculpture in the United States after Europeans' arrival reflects the country's 18th-century foundation in Roman republican civic values and Protestant Christianity.
Compared to areas colonized by the Spanish, sculpture got off to an extremely slow start in the British colonies, with next to no place in churches, and was only given impetus by the need to assert nationality after independence.
American sculpture of the mid- to late-19th century was often classical, often romantic, but showed a bent for a dramatic, narrative, almost journalistic realism. Public buildings during the last quarter of the 19th century and the first half of the 20th century often provided an architectural setting for sculpture, especially in relief. By the 1950s, traditional sculpture education would almost be completely replaced by a Bauhaus-influenced concern for abstract design. Minimalist sculpture replaced the figure in public settings and architects almost completely stopped using sculpture in or on their designs. Modern sculptors (21st century) use both classical and abstract inspired designs. Beginning in the 1980s, there was a swing back toward figurative public sculpture; by 2000, many of the new public pieces in the United States were figurative in design.
Europe
The earliest European sculpture to date portrays a female form, and has been estimated at dating from 35,000 years ago. The discovery in 2008 has caused experts to revise the history of the development of art.
Greek-Roman-classical
Features unique to the European Classical tradition:
full figures: using the young, athletic male or full-bodied female nude
portraits: showing signs of age and strong character
use of classical costume and attributes of classical deities
Concern for naturalism based on observation, often from live models.
Features that the European Classical tradition shares with many others:
characters present an attitude of distance and inner contentment
details do not disrupt a sense of rhythm between solid volumes and the spaces that surround them
pieces feel solid and larger than they really are
ambient space feels sacred or timeless
The topic of Nudity
An unadorned figure in Greek classical sculpture was a reference to the status or role of the depicted person, deity or other being. Athletes, priestesses and gods could be identified by their adornment or lack of it.
The Renaissance preoccupation with Greek classical imagery, such as the 5th century B.C. Doryphoros of Polykleitos, led to nude figurative statues being seen as the 'perfect form' of representation for the human body. Subsequently, nudity in sculpture and painting has often represented a form of ideal, be it innocence, openness or purity.
Nude sculptures are still common. As in painting, they are often made as exercises in efforts to understand the anatomical structure of the human body and develop skills that will provide a foundation for making clothed figurative work.
Nude statues are usually widely accepted by many societies, largely due to the length of tradition that supports this form. Occasionally, the nude form draws objections, often by moral or religious groups. Classic examples of this are the removal of the parts of Greek sculpture corresponding to male genitals (in the Vatican collection), and the addition of a fig leaf to a plaster cast of Michelangelo's sculpture of David for Queen Victoria's visit to the British Museum.

Gothic
Gothic sculpture, late 15th century.
Gothic sculpture evolved from the early stiff and elongated style, still partly Romanesque, into a spatial and naturalistic feel in the late 12th and early 13th century. The architectural statues at the Western (Royal) Portal at Chartres Cathedral (c. 1145) are the earliest Gothic sculptures and were a revolution in style and the model for a generation of sculptors.
Prior to this there had been no sculpture tradition in Ile-de-France—so sculptors were brought in from Burgundy. Bamberg Cathedral had the largest assemblage of 13th century sculpture. In England sculpture was more confined to tombs and non-figurine decorations. In Italy there was still a Classical influence, but Gothic made inroads in the sculptures of pulpits such as the Pisa Baptistery pulpit (1260) and the Siena pulpit (1268). Dutch-Burgundian sculptor Claus Sluter and the taste for naturalism signaled the beginning of the end of Gothic sculpture, evolving into the classicistic Renaissance style by the end of the 15th century.
Although the Renaissance began at different times in various parts of Europe (some areas created art longer in the Gothic style than other areas) the transition from Gothic to Renaissance in Italy was signalled by a trend toward naturalism with a nod to classical sculpture.
One of the most important sculptors in the classical revival was Donatello. The greatest achievement of what art historians refer to as his classic period is the bronze statue entitled David (not to be confused with Michelangelo's David), which is currently located at the Bargello in Florence.
At the time of its creation, it was the first free-standing nude statue since ancient times. Conceived fully in the round and independent of any architectural surroundings, it is generally considered to be the first major work of Renaissance sculpture. The movement affected all aspects of art, in all parts of Italy; as represented by the conscious revival from archaeological sources of the Antique dining table, by the great sculptor Tullio Lombardo, for the Castello di Roncade in the Veneto (the house with the first free-standing pediment since antiquity.)
During the main Renaissance, the time from about 1500 to 1520, Michelangelo was an active sculptor with works such as David and the Pietà, as well as the Doni Virgin, Bacchus, Moses, Rachel, Orgetorix, and members of the Medici family. Michelangelo's David is possibly the most famous sculpture in the world, which was unveiled on September 8, 1504. It is an example of the contrapposto style of posing the human figure, which again borrows from classical sculpture. Michelangelo's statue of David differs from previous representations of the subject in that David is depicted before his battle with Goliath and not after the giant's defeat. Instead of being shown victorious over a foe much larger than he, David looks tense and battle ready.

During the Mannerist period, more abstract representations were praised, (such as the "figura serpentinata" or "twisted figure") giving more thought to color and composition rather than realistic portrayal of the subjects in the piece.
This is exemplified in Giambologna's Abduction/Rape of the Sabine Women, where the figures are not positioned in a way which is at all comfortable, or even humanly possible, but the position and emotion still come across. Another exemple of the form is Benvenuto Cellini's 1540 salt cellar of gold and ebony, featuring Neptune and Amphitrite (earth and water) in elongated form and uncomfortable positions (implausible poses).
In Baroque sculpture, groups of figures assumed new importance, and there was a dynamic movement and energy of human forms— they spiralled around an empty central vortex, or reached outwards into the surrounding space. For the first time, Baroque sculpture often had multiple ideal viewing angles.
The characteristic Baroque sculpture added extra-sculptural elements, for example, concealed lighting, or water fountains. Often, Baroque artists fused sculpture and architecture seeking to create a transformative experience for the viewer. Gian Lorenzo Bernini was undoubtedly the most important sculptor of the Baroque period. His works were inspired by Hellenistic sculpture of Ancient Greece and Imperial Rome. One of his most famous works is The Ecstasy of St Theresa (1647-1652).
The Neoclassical period (c.1750-1850) was one of the great ages of public sculpture, though its "classical" prototypes were more likely to be Roman copies of Hellenistic sculptures. In sculpture, the most familiar representatives are the Italian Antonio Canova, the Englishman John Flaxman and the Dane Bertel Thorvaldsen. The European neoclassical manner also took hold in the United States, where its pinnacle occurred somewhat later and is exemplified in the sculptures of Hiram Powers.
Modern Classicism
Modern Classicism contrasted in many ways with the classical sculpture of the 19th century which was characterized by commitments to naturalism (Antoine-Louis Barye) -- the melodramatic (François Rude) sentimentality (Jean Baptiste Carpeaux)-- or a kind of stately grandiosity (Lord Leighton) Several different directions in the classical tradition were taken as the century turned, but the study of the live model and the post-Renaissance tradition was still fundamental to them.
Auguste Rodin was the most renowned European sculptor of the early 20th century. He is often considered a sculptural Impressionist, as are Medardo Rosso, Count Troubetski, Rik Wouters, and Hugo Rheinhold, attempting to model of a fleeting moment of ordinary life.
Modern Classicism showed a lesser interest in naturalism and a greater interest in formal stylization. Greater attention was paid to the rhythms of volumes and spaces - as well as greater attention to the contrasting qualities of surface (open, closed, planar, broken etc) while less attention was paid to story-telling and convincing details of anatomy or costume.
Greater attention was given to psychological effect than to physical realism. Greater attention was given to showing what was eternal and public, rather than what was momentary and private. Greater attention was given to examples of ancient and Medieval sacred arts:Egyptian, Middle Eastern, Asian, African, and Meso-American. Grandiosity was still a concern, but in a broader, more worldwide context.
As the century progressed, modern classicism was adopted as the national style of the two great European totalitarian empires: Nazi Germany and Soviet Russia, who co-opted the work of early masters, like Kolbe and Arno Breker in Germany, and Matveev in Russia.
Nazi Germany had a 15-year run; but over the 70 years of the USSR, new generations of sculptors were trained and chosen within their system, and a distinct style, socialist realism, developed, that returned to the 19th century's emphasis on melodrama and naturalism.
Classical training was rooted out of art education in Western Europe (and the Americas) by 1970 and the classical variants of the 20th century were marginalized in the history of modernism. But classicism continued as the foundation of art education in the Soviet academies until 1990, providing a foundation for expressive figurative art throughout eastern Europe and parts of the Middle East.
By the year 2000, the European classical tradition maintains a wide appeal to viewers - especially tourists - and especially for the ancient, Renaissance, Baroque, and 19th century periods—but awaits an educational tradition to revive its contemporary development.
In the early days of the 20th century Pablo Picasso revolutionized the art of sculpture when he began creating his constructions fashioned by combining disparate objects and materials into one constructed piece of sculpture, - by addition. Picasso reinvented the art of sculpture with his innovative use of constructing a work in three dimensions with disparate material.
Just as collage was a radical development in two dimensional art; so was construction a radical development in three dimensional sculpture. The advent of Surrealism lead to things occasionally being described as "sculpture" that would not have been so previously, such as "involuntary sculpture" in several senses, including coulage.
Similarly, the work of Constantin Brâncuşi at the beginning of the century paved the way for later abstract sculpture. In revolt against the naturalism of Rodin and his late 19th century contemporaries, Brancusi distilled subjects down to their essences as illustrated by his Bird in Space (1924) series. These elegantly refined forms became synonymous with 20th century sculpture. In 1927, Brancusi won a lawsuit against the U.S. customs authorities who attempted to value his sculpture as raw metal. The suit led to legal changes permitting the importation of abstract art free of duty.
Since the 1950s Modernist trends in sculpture both abstract and figurative have dominated the public imagination and the popularity of Modernist sculpture has all but eliminated the traditional approach.
During the 1960s and 1970s figurative sculpture by modernist artists as stylized as Leonard Baskin, Ernest Trova, Marisol Escobar, Paul Thek and Manuel Neri became popular, and by the 1980s the painter Fernando Botero emerged with monumental figures reminiscent of the fat characters in his paintings.
Picasso was commissioned to make a maquette for a huge 50-foot (15 m)-high public sculpture to be built in Chicago, known usually as the Chicago Picasso. He approached the project with a great deal of enthusiasm, designing a sculpture which was ambiguous and somewhat controversial. What the figure represents is not known; it could be a bird, a horse, a woman or a totally abstract shape. The sculpture, one of the most recognizable landmarks in downtown Chicago, was unveiled in 1967. Picasso refused to be paid $100,000 for it, donating it to the people of the city.
During the late 1950s and the 1960s abstract sculptors began experimenting with a wide array of new materials and different approaches to creating their work. Surrealist imagery, anthropomorphic abstraction, new materials and combinations of new energy sources and varied surfaces and objects became characteristic of much new modernist sculpture.
The term found art — more commonly found object (French: objet trouvé) or readymade — describes art created from the undisguised, but often modified, use of objects that are not normally considered art, often because they already have a mundane, utilitarian function. Marcel Duchamp was the originator of this in the early 20th-century with pieces such as Fountain.
Post-modern sculpture occupies a broader field of activities than Modernist sculpture, as Rosalind Krauss has observed. Her idea of sculpture in the expanded field identified a series of oppositions that describe the various sculpture-like activities that are post-modern sculpture:
Site-Construction is the intersection of landscape and architecture
Axiomatic Structures is the combination of architecture and not-architecture
Marked sites is the combination of landscape and not-landscape
Sculpture is the intersection of not-landscape and not-architecture
Krauss' concern was creating a theoretical explanation that could adequately fit the developments of Land art, Minimalist sculpture, and Site-specific art into the category of sculpture. To do this, her explanation created a series of oppositions around the work's relationship to its environment.
Contemporary genres
Some modern sculpture forms are now practiced outdoors, and often in full view of spectators, thus giving them kinship to performance art in the eyes of some.
Ice sculpture is a form of sculpture that uses ice as the raw material. It's popular in China, Japan, Canada, Sweden, and Russia. Ice sculptures feature decoratively in some cuisines, especially in Asia. Kinetic sculptures are sculptures that are designed to move, which include Mobiles. Snow sculptures are usually carved out of a single block of snow about 6 to 15 feet (4.6 m) on each side and weighing about 20 - 30 tons.
The snow is densely packed into a form after having been produced by artificial means or collected from the ground after a snowfall. Sound sculptures take the form of indoor sound installations, outdoor installations such as aeolian harps, automatons, or be more or less near conventional musical instruments. Sound sculpture is often site-specific.
A Sand castle can be regarded as a sand sculpture. Weightless Sculpture (in outer space) as a concept is created in 1985 by the Dutch artist Martin Sjardijn. Lego brick sculpting involves the use of common Lego bricks to build realistic or artistic sculptures sometimes using hundreds of thousands of bricks. Art toys have become an important format for contemporary artists since the late 1990s, such as those produced by Kid Robot, designed by Michael Lau, or hand-made by Michael Leavitt (artist).
Worldwide, sculptors have usually been tradesmen whose work is unsigned. But in the Classical world, many Ancient Greek sculptors like Phidias began to receive individual recognition in Periclean Athens, and became famous and presumably wealthy. In the Middle Ages, artists like the 12th century Gislebertus sometimes signed their work, and were sought after by different cities, especially from the Trecento onwards in Italy, with figures like Arnolfo di Cambio, Nicola Pisano and his son Giovanni.
From the High Renaissance artists like Michelangelo, Leone Leoni and Giambologna could become wealthy, and ennobled, and enter the circle of princes. Much decorative sculpture on buildings remained a trade, but sculptors producing individual pieces were recognised on a level with painters. From at least the 18th century, sculpture also attracted middle-class students, although it was slower to do so than painting. Equally women sculptors took longer to appear than women painters, and have generally been less prominent until the 20th century at least.
Techniques
Stone carving
Stone carving is an ancient activity where pieces of rough natural stone are shaped by the controlled removal of stone. Owing to the permanence of the material, evidence can be found that even the earliest societies indulged in some form of stone work.
Petroglyphs (also called rock engravings) are perhaps the earliest form: images created by removing part of a rock surface which remains in situ, by incising, pecking, carving, and abrading. Monumental sculpture covers large works, and architectural sculpture, which is attached to buildings.
Bronze is the most popular metal for cast metal sculptures; a cast bronze sculpture is often called simply a "bronze". Common bronze alloys have the unusual and desirable property of expanding slightly just before they set, thus filling the finest details of a mold. Their strength and lack of brittleness (ductility) is an advantage when figures in action are to be created, especially when compared to various ceramic or stone materials (see marble sculpture for several examples).
Wood carving is a form of working wood by means of a cutting tool held in the hand (this may be a power tool), resulting in a wooden figure or figurine (this may be abstract in nature) or in the sculptural ornamentation of a wooden object.
Casting
Casting is a manufacturing process by which a liquid material is (usually) poured into a mold, which contains a hollow cavity of the desired shape, and then allowed to solidify. The solid casting is then ejected or broken out to complete the process. Casting may be used to form hot liquid metals or various materials that cold set after mixing of components (such as epoxies, concrete, plaster and clay). Casting is most often used for making complex shapes that would be otherwise difficult or uneconomical to make by other methods.
Casting is a 6,000-year-old process.The oldest surviving casting is a copper frog from 3200 BC.The casting process is subdivided into two distinct subgroups: expendable and non-expendable mold casting.
Sculptures are sensitive to environmental conditions such as temperature, humidity and exposure to light and ultraviolet light. Acid rain can also cause damage to certain building materials and historical monuments. This results when the sulfuric acid in the rain chemically reacts with the calcium compounds in the stones (limestone, sandstone, marble and granite) to create gypsum, which then flakes off.

Pottery is the ceramic ware made by potters. Major types of pottery include earthenware, stoneware, and porcelain. The places where such wares are made are called potteries. Pottery is one of the oldest human technologies and art-forms, and remains a major industry today. Ceramic art covers the art of pottery, whether in items made for use or purely for decoration.
Background
Pottery is made by forming a clay body into objects of a required shape and heating them to high temperatures in a kiln to induce reactions that lead to permanent changes, including increasing their strength and hardening and setting their shape. There are wide regional variations in the properties of clays used by potters and this often helps to produce wares that are unique in character to a locality. It is common for clays and other minerals to be mixed to produce clay bodies suited to specific purposes.
Prior to some shaping processes, air trapped within the clay body needs to be removed. This is called de-airing and can be accomplished by a machine called a vacuum pug or manually by wedging. Wedging can also help to ensure an even moisture content throughout the body.
Once a clay body has been de-aired or wedged, it is shaped by a variety of techniques. After shaping it is dried before firing. There are a number of stages in the drying process. Leather-hard refers to the stage when the clay object is approximately 75-85% dry. Clay bodies at this stage are very firm and only slightly pliable. Trimming and handle attachment often occurs at the leather-hard state. Clay bodies are said to be "bone-dry" when they reach a moisture content at or near 0%. Unfired objects are often termed greenware. Clay bodies at this stage are very fragile and hence can be easily broken.
Methods of shaping
A man shapes pottery as it turns on a wheel. (Cappadocia, Turkey).
The potter's most basic tool is the hand. However, many additional tools have been developed over the long history of pottery manufacturing, including the potter's wheel and turntable, shaping tools (paddles, anvils, ribs), rolling tools (roulettes, slab rollers, rolling pins), cutting/piercing tools (knives, fluting tools, wires) and finishing tools (burnishing stones, rasps, chamois).
Pottery can be shaped by a range of methods that include:
Handwork or hand building. This is the earliest and the most individualized and direct forming method. Wares can be constructed by hand from coils of clay, from flat slabs of clay, from solid balls of clay — or some combination of these. Parts of hand-built vessels are often joined together with the aid of slurry or slip, a runny mixture of clay and water. Hand building is slower and more gradual than wheel-throwing, but it offers the potter a high degree of control over the size and shape of wares. While it isn't difficult for an experienced potter to make identical pieces of hand-built pottery, the speed and repetitiveness of wheel-throwing is more suitable for making precisely matched sets of wares such as table wares. Some studio potters find hand building more conducive to fully using the imagination to create one-of-a-kind works of art, while others find this with the wheel.
A potter shapes a piece of pottery on an electric-powered potter's wheel
The potter's wheel. In the process that is called "throwing" (coming from the Old English word thrawan, which means to twist or turn) , a ball of clay is placed in the center of a turntable, called the wheel-head, which the potter rotates with a stick, or with foot power (a kick wheel or treadle wheel) or with a variable speed electric motor. (Often, a disk of plastic, wood or plaster — called a bat — is first set on the wheel-head, and the ball of clay is thrown on the bat rather than the wheel-head so that the finished piece can be removed intact with its bat, without distortion.)
During the process of throwing the wheel rotates rapidly while the solid ball of soft clay is pressed, squeezed, and pulled gently upwards and outwards into a hollow shape.
The first step, of pressing the rough ball of clay downward and inward into perfect rotational symmetry, is called centering the clay, a most important (and often most difficult) skill to master before the next steps: opening (making a centered hollow into the solid ball of clay), flooring (making the flat or rounded bottom inside the pot), throwing or pulling (drawing up and shaping the walls to an even thickness), and trimming or turning (removing excess clay to refine the shape or to create a foot).
From around 7th century BC until the introduction of slip casting in the 18th century AD, the potter's wheel was the most effective method of mass producing pottery, although it is also often employed to make individual pieces. Wheel-work makes great demands on the skill of the potter, but an accomplished operator can make many near-identical plates, vases, or bowls in the course of a day's work. Because of its inherent limitations, wheel-work can only be used to create wares with radial symmetry on a vertical axis. These can then be altered by impressing, bulging, carving, fluting, faceting, incising, and by other methods making the wares more visually interesting. Often, thrown pieces are further modified by having handles, lids, feet, spouts, and other functional aspects added using the techniques of handworking.
Jiggering and jolleying: These operations are carried out on the potter's wheel and allow the time taken to bring wares to a standardized form to be reduced. Jiggering is the operation of bringing a shaped tool into contact with the plastic clay of a piece under construction, the piece itself being set on a rotating plaster mould on the wheel. The jigger tool shapes one face whilst the mould shapes the other. Jiggering is used only in the production of flat wares, such as plates, but a similar operation, jolleying, is used in the production of hollow-wares, such as cups. Jiggering and jolleying have been used in the production of pottery since at least the 18th century. In large-scale factory production jiggering and jolleying are usually automated, which allows the operations to be carried out by semi-skilled labor.

Roller-head machine: This machine is for shaping wares on a rotating mould, as in jiggering and jolleying, but with a rotary shaping tool replacing the fixed profile. The rotary shaping tool is a shallow cone having the same diameter as the ware being formed and shaped to the desired form of the back of the article being made. Wares may in this way be shaped, using relatively unskilled labor, in one operation at a rate of about twelve pieces per minute, though this varies with the size of the articles being produced. The roller-head machine is now used in factories worldwide.
RAM pressing: A factory process for shaping table wares and decorative ware by pressing a bat of prepared clay body into a required shape between two porous molding plates. After pressing, compressed air is blown through the porous mould plates to release the shaped wares.
Granulate pressing: As the name suggests, this is the operation of shaping pottery by pressing clay in a semi-dry and granulated condition in a mould. The clay is pressed into the mould by a porous die through which water is pumped at high pressure. The granulated clay is prepared by spray-drying to produce a fine and free flowing material having a moisture content of between about five and six per cent. Granulate pressing, also known as dust pressing, is widely used in the manufacture of ceramic tiles and, increasingly, of plates.
Slipcasting: is often used in the mass-production of ceramics and is ideally suited to the making of wares that cannot be formed by other methods of shaping. A slip, made by mixing clay body with water, is poured into a highly absorbent plaster mold. Water from the slip is absorbed into the mould leaving a layer of clay body covering its internal surfaces and taking its internal shape. Excess slip is poured out of the mold, which is then split open and the molded object removed. Slipcasting is widely used in the production of sanitary wares and is also used for making smaller articles, such as intricately-detailed figurines.
Additives can be worked into the clay body prior to forming, to produce desired effects in the fired wares. Coarse additives, such as sand and grog (fired clay which has been finely ground) are sometimes used to give the final product a required texture. Contrasting colored clays and grogs are sometimes used to produce patterns in the finished wares. Colorants, usually metal oxides and carbonates, are added singly or in combination to achieve a desired color. Combustible particles can be mixed with the body or pressed into the surface to produce texture.
Agateware: So-named after its resemblance to the quartz mineral agate which has bands or layers of color that are blended together. Agatewares are made by blending clays of differing colors together, but not mixing them to the extent that they lose their individual identities. The wares have a distinctive veined or mottled appearance. The term 'agateware' is used to describe such wares in the United Kingdom; in Japan the term neriage is used and in China, where such things have been made since at least the Tang Dynasty, they are called marbled wares. Great care is required in the selection of clays to be used for making agatewares as the clays used must have matching thermal movement characteristics.
Banding: This is the application, by hand or by machine, of a band of color to the edge of a plate or cup. Also known as lining, this operation is often carried out on a potter's wheel.
Burnishing: The surface of pottery wares may be burnished prior to firing by rubbing with a suitable instrument of wood, steel or stone, to produce a polished finish that survives firing. It is possible to produce very highly polished wares when fine clays are used, or when the polishing is carried out on wares that have been partially dried and contain little water, though wares in this condition are extremely fragile and the risk of breakage is high.
Engobe: This is a clay slip, often white or cream in color that is used to coat the surface of pottery, usually before firing. Its purpose is often decorative, though it can also be used to mask undesirable features in the clay to which it is applied. Engobe slip may be applied by painting or by dipping, to provide a uniform, smooth, coating.
Engobe has been used by potters from pre-historic times until the present day, and is sometimes combined with sgraffito decoration, where a layer of engobe is scratched through to reveal the color of the underlying clay. With care it is possible to apply a second coat of engobe of a different color to the first and to incise decoration through the second coat to expose the color of the underlying coat. Engobes used in this way often contain substantial amounts of silica, sometimes approaching the composition of a glaze.
Litho: This is a commonly used abbreviation for lithography, although the alternative names of transfer print or decal are also common. These are used to apply designs to articles. The litho comprises three layers: the color, or image, layer which comprises the decorative design; the cover coat, a clear protective layer, which may incorporate a low-melting glass; and the backing paper on which the design is printed by screen printing or lithography. There are various methods of transferring the design while removing the backing-paper, some of which are suited to machine application.
Gold: Decoration with gold is used on some high quality ware. Different methods exist for its application, including:
Best gold - a suspension of gold powder in essential oils mixed with a flux and a mercury salt extended. This can be applied by a painting technique. From the kiln the decoration is dull and requires burnishing to reveal the full color
Acid Gold – a form of gold decoration developed in the early 1860s at the English factory of Mintons Ltd, Stoke-on-Trent. The glazed surface is etched with diluted hydrofluoric acid prior to application of the gold. The process demands great skill and is used for the decoration only of ware of the highest class.
Bright Gold – consists of a solution of gold sulphoresinate together with other metal resonates and a flux. The name derives from the appearance of the decoration immediately after removal from the kiln as it requires no burnishing
Mussel Gold – an old method of gold decoration. It was made by rubbing together gold leaf, sugar and salt, followed by washing to remove solubles
Glazing
Glaze is a glassy coating applied to pottery, the primary purposes of which include decoration and protection. Glazes are highly variable in composition but usually comprise a mixture of ingredients that generally, but not always, mature at kiln temperatures lower than that of the pottery that it coats.
One important use of glaze is in rendering pottery vessels impermeable to water and other liquids. Glaze may be applied by dusting it over the clay, spraying, dipping, trailing or brushing on a thin slurry composed of glaze minerals and water. Brushing tends not to give an even covering but can be effective as a decorative technique.
The color of a glaze before it has been fired may be significantly different than afterwards. To prevent glazed wares sticking to kiln furniture during firing, either a small part of the object being fired (for example, the foot) is left unglazed or, alternatively, special refractory spurs are used as supports. These are removed and discarded after the firing.
Special methods of glazing are sometimes carried out in the kiln. One example is salt-glazing, where common salt is introduced to the kiln to produce a glaze of mottled, orange peel texture. Materials other than salt are also used to glaze wares in the kiln, including sulfur. In wood-fired kilns fly-ash from the fuel can produce ash-glazing on the surface of wares, and the use of an ash and clay mix can result in alkaline glazes, as used in Catawba Valley Pottery in the eastern United States.
Firing
Firing produces irreversible changes in the body. It is only after firing that the article can be called pottery. In lower-fired pottery the changes include sintering, the fusing together of coarser particles in the body at their points of contact with each other.
In the case of porcelain, where different materials and higher firing-temperatures are used the physical, chemical and mineralogical properties of the constituents in the body are greatly altered.
In all cases the object of firing is to permanently harden the wares and the firing regime must be appropriate to the materials used to make them. As a rough guide, earthenwares are normally fired at temperatures in the range of about 1000 to 1200 degrees Celsius; stonewares at between about 1100 to 1300 degrees Celsius; and porcelains at between about 1200 to 1400 degrees Celsius.
However, the way that ceramics mature in the kiln is influenced not only by the peak temperature achieved, but also by the duration of the period of firing. Thus, the maximum temperature within a kiln is often held constant for a period of time to soak the wares, to produce the maturity required in the body of the wares.
The atmosphere within a kiln during firing can affect the appearance of the finished wares. An oxidising atmosphere, produced by allowing air to enter the kiln, can cause the oxidation of clays and glazes. A reducing atmosphere, produced by limiting the flow of air into the kiln, can strip oxygen from the surface of clays and glazes. This can affect the appearance of the wares being fired and, for example, some glazes containing iron fire brown in an oxidising atmosphere, but green in a reducing atmosphere. The atmosphere within a kiln can be adjusted to produce complex effects in glaze.
Kilns may be heated by burning wood, coal and gas, or by electricity. When used as fuels, coal and wood can introduce smoke, soot and ash into the kiln which can affect the appearance of unprotected wares. For this reason wares fired in wood- or coal-fired kilns are often placed in the kiln in saggars; lidded ceramic boxes, to protect them. Modern kilns powered by gas or electricity are cleaner and more easily controlled than older wood- or coal-fired kilns and often allow shorter firing times to be used. In a Western adaptation of traditional Japanese Raku ware firing, wares are removed from the kiln while hot and smothered in ashes, paper or woodchips, which produces a distinctive, carbonised, appearance. This technique is also used in Malaysia in creating traditional labu sayung.
History
Earliest known ceramics are the Gravettian figurines that date to 29,000 to 25,000 BC
It is believed that the earliest pottery wares were hand-built and fired in bonfires. Firing times were short but the peak-temperatures achieved in the fire could be high, perhaps in the region of 900 degrees Celsius, and were reached very quickly.
Clays tempered with sand, grit, crushed shell or crushed pottery were often used to make bonfire-fired ceramics, because they provided an open body texture that allows water and other volatile components of the clay to escape freely. The coarser particles in the clay also acted to restrain shrinkage within the bodies of the wares during cooling, which was carried out slowly to reduce the risk of thermal stress and cracking.
In the main, early bonfire-fired wares were made with rounded bottoms, to avoid sharp angles that might be susceptible to cracking. The earliest intentionally constructed kilns were pit-kilns or trench-kilns; holes dug in the ground and covered with fuel. Holes in the ground provided insulation and resulted in better control over firing.
The earliest known ceramic objects are Gravettian figurines such as those discovered at Dolni Vestonice in the modern-day Czech Republic. The Venus of Dolní Věstonice (Věstonická Venuše in Czech) is a Venus figurine, a statuette of a nude female figure dated to 29,000–25,000 BCE (Gravettian industry). The earliest pottery ware found to date was excavated from the Yuchanyan Cave in southern China and the Proceedings of the National Academy of Sciences in 2009 reports that the ware dates back to 18,000 years ago.
Pottery vessels made by the Incipient Jōmon people of Japan from around 10,500 BCE have also been found. The term "Jōmon" means "cord-marked" in Japanese. This refers to the markings made on clay vessels and figures using sticks with cords wrapped around them. Pottery which dates back to 10,000 BCE have also been excavated in China.
It appears that pottery was independently developed in North Africa during the tenth millennium b.p. and in South America during the seventh millennium b.p.
The invention of the potter's wheel in Mesopotamia sometime between 6,000 and 4,000 BCE (Ubaid period) revolutionized pottery production. Specialized potters were then able to meet the expanding needs of the world's first cities. Pottery was in use in ancient India during the Mehrgarh Period II (5500 - 4800 BCE) and Merhgarh Period III (4800 - 3500 BCE), known as the ceramic Neolithic and chalcolithic. Pottery, including items known as the ed-Dur vessels, originated in regions of the Indus valley and has been found in a number of sites in the Indus valley civilization.
In the Mediterranean, during the Greek Dark Ages (1100–800 BCE), artists used geometric designs such as squares, circles and lines to decorate amphoras and other pottery. The period between 1500-300 BCE in ancient Korea is known as the Mumun Pottery Period.
The quality of pottery has varied historically, in part dependent upon the repute in which the potter's craft was held by the community. For example, in the Chalcolithic period in Mesopotamia, Halafian pottery achieved a level of technical competence and sophistication, not seen until the later developments of Greek pottery with Corinthian and Attic ware. The distinctive Red Samian ware of the Early Roman Empire was copied by regional potters throughout the Empire. The Dark Age period saw a collapse in the quality of European pottery which did not recover in status and quality until the European Renaissance.
In archaeology
Pottery found at Çatal Höyük - sixth millennium BC
For archaeologists, anthropologists, and historians the study of pottery can help to provide an insight into past cultures. Pottery is durable and fragments, at least, often survive long after artifacts made from less-durable materials have decayed past recognition.
Combined with other evidence, the study of pottery artifacts is helpful in the development of theories on the organisation, economic condition and the cultural development of the societies that produced or acquired pottery. The study of pottery may also allow inferences to be drawn about a culture's daily life, religion, social relationships, attitudes towards neighbours, attitudes to their own world and even the way the culture understood the universe.
Chronologies based on pottery are often essential for dating non-literate cultures and are often of help in the dating of historic cultures as well. Trace element analysis, mostly by neutron activation, allows the sources of clay to be accurately identified and the thermoluminescence test can be used to provide an estimate of the date of last firing. Examining fired pottery shards from prehistory, scientists learned that during high-temperature firing, iron materials in clay record the exact state of Earth's magnetic field at that exact moment.
Environmental issues in production
Although many of the environmental effects of pottery production have existed for millennia, some of these have been amplified with modern technology and scales of production. The principal factors for consideration fall into two categories:
Historically plumbism, lead poisoning, was a significant health concern to those glazing pottery. This was recognised at least as early as the nineteenth century, and the first legislation in the United Kingdom to limit pottery workers’ exposure was introduced in 1899.
Whilst the risk of to those working in ceramics is now much reduced it can still not be ignored. With respect to indoor air quality, workers can be exposed to fine particulate matter, carbon monoxide and certain heavy metals. The greatest health risk is the potential to develop silicosis from the long-term exposure to crystalline silica. Proper ventilation can reduce the risks, and the first legislation in the United Kingdom to govern ventilation was introduced in 1899. Another, more recent study at Laney College, Oakland, California suggests that all these factors can be controlled in a well designed workshop environment.
The use of energy and pollutants in the production of ceramics is a growing concern. Electric firing is arguably more environmentally friendly than combustion firing, although the source of the electricity varies in environmental impact.[citation needed]
Other usages
Due to the large number of pottery factories, or colloquially, 'Pot Banks', the English city of Stoke-on-Trent, one of the first industrial cities of the modern era where, as early as 1785, two hundred pottery manufacturers employed 20,000 workers, is often called "The Potteries". For the same reason the largest football club in the city are known as "The Potters".
