In the art world, if an artwork exists in several versions, the one known or believed to be the earliest is called the prime version. Many artworks produced in media such as painting or carved sculpture which create unique objects are in fact repeated by their artists, often several times. It is regarded as a matter of some importance both by art historians and the art market to establish which version has "priority", that is to say was the original work. The presumption usually is that the prime version is the finest, and perhaps the most carefully done, though some later versions can be argued to improve on the originals.

In many periods the later "repetitions" were often produced by the workshop of the master, with varying degrees of supervision and direct attention from him. This was especially the case with official portraits of monarchs and politicians, which in the Early Modern period were often ordered in large numbers of versions from the court artist as diplomatic gifts. "Prime version" is normally only used when there is another version by the same artist, or his workshop. Other versions by other artists are called copies. Sometimes "reduced versions" that are considerably smaller than the prime one are made. Especially in the case of 19th-century repetitions, the term autograph replica is used of repetitions by the original artist. (Full article...)

The idea of founding a theory of painting after the model of music theory was suggested by Goethe in 1807 and gained much regard among the avant-garde artists of the 1920s, the Weimar culture period, like Paul Klee. (Full article...)

The conservation and restoration of paintings is carried out by professional painting conservators. Paintings cover a wide range of various mediums, materials, and their supports (i.e. the painted surface made from fabric, paper, wood panel, fabricated board, or other). Painting types include fine art to decorative and functional objects spanning from acrylics, frescoes, and oil paint on various surfaces, egg tempera on panels and canvas, lacquer painting, water color and more. Knowing the materials of any given painting and its support allows for the proper restoration and conservation practices. All components of a painting will react to its environment differently, and impact the artwork as a whole. These material components along with collections care (also known as preventive conservation) will determine the longevity of a painting. The first steps to conservation and restoration is preventive conservation followed by active restoration with the artist's intent in mind. (Full article...)

The Jerwood Painting Prize was a prize for originality and excellence in painting in the United Kingdom, awarded and funded by the Jerwood Foundation. It was open to all artists born or resident in the UK, regardless of age or reputation. Winners of the prize include Craigie Aitchison, Patrick Caulfield, Prunella Clough and Maggi Hambling. The prize was instituted in 1994, and at £30,000 was the largest of its kind in Britain. The prize is no longer awarded. (Full article...)

The history of Western painting represents a continuous, though disrupted, tradition from antiquity until the present time. Until the mid-19th century it was primarily concerned with representational and traditional modes of production, after which time more modern, abstract and conceptual forms gained favor.

Initially serving imperial, private, civic, and religious patronage, Western painting later found audiences in the aristocracy and the middle class. From the Middle Ages through the Renaissance painters worked for the church and a wealthy aristocracy. Beginning with the Baroque era artists received private commissions from a more educated and prosperous middle class. The idea of "art for art's sake" began to find expression in the work of the Romantic painters like Francisco de Goya, John Constable, and J. M. W. Turner. During the 19th century commercial galleries became established and continued to provide patronage in the 20th century. (Full article...)

An "overdoor" (or "Supraporte" as in German, or "sopraporte" as in Italian) is a painting, bas-relief or decorative panel, generally in a horizontal format, that is set, typically within ornamental mouldings, over a door, or was originally intended for this purpose. (Full article...)

Self-portraits are portraits artists make of themselves. Although self-portraits have been made since the earliest times, it is not until the mid-15th century that artists can be frequently identified depicting themselves, as either the main subject or important characters in their work. With better and cheaper mirrors, and the advent of the panel portrait, many painters, sculptors and printmakers tried some form of self-portraiture. Portrait of a Man in a Turban by Jan van Eyck of 1433 may well be the earliest known panel self-portrait. He painted a separate portrait of his wife, and he belonged to the social group that had begun to commission portraits, already more common among wealthy Netherlanders than south of the Alps. The genre is venerable, but not until the Renaissance, with increased wealth and interest in the individual as a subject, did it become truly popular.

By the Baroque period, most artists with an established reputation at least left drawings of themselves. Printed portraits of artists had a market, and many were self-portraits. They were also sometimes given as gifts to family and friends. If nothing else, they avoided the need to arrange for a model, and for the many professional portrait-painters, a self-portrait kept in the studio acted as a demonstration of the artist's skill for potential new clients. The unprecedented number of self-portraits by Rembrandt, both as paintings and prints, made clear the potential of the form, and must have further encouraged the trend. (Full article...)

Live painting is a form of visual performance art in which artists complete a visual art piece in a public performance, often at a bar, music concert, wedding reception, or public event, accompanied by a DJ or live music. The artwork which is created live may be planned or improvisational. This live art form is often contrasted with more studied fine art compositions from the same artists, which are generally executed in an artist studio or other private space.

Artists in a number of genres have performed live painting, including LeRoy Neiman creating a painting during the 1976 Summer Olympics. In the 1990s and 2000s, live painting became a hallmark of street art and graffiti artists. (Full article...)

Inscape, in visual art, is a term especially associated with certain works of Chilean artist Roberto Matta, but it is also used in other senses within the visual arts. Though the term inscape has been applied to stylistically diverse artworks, it usually conveys some notion of representing the artist's psyche as a kind of interior landscape. The word inscape can therefore be read as a kind of portmanteau, combining interior (or inward) with landscape. (Full article...)

In visual art, mixed media describes artwork in which more than one medium or material has been employed.
Assemblages, collages, and sculpture are three common examples of art using different media. Materials used to create mixed media art include, but are not limited to, paint, cloth, paper, wood and found objects.

Mixed media art is distinguished from multimedia art which combines visual art with non-visual elements, such as recorded sound, literature, drama, dance, motion graphics, music, or interactivity. (Full article...)

Watercolor (American English) or watercolour (Commonwealth English; see spelling differences), also aquarelle (French: [akwaʁɛl]; from Italian diminutive of Latin aqua 'water'), is a painting method in which the paints are made of pigments suspended in a water-based solution. Watercolor refers to both the medium and the resulting artwork.

The conventional and most common support—material to which the paint is applied—for watercolor paintings is paper, usually special types of watercolor paper. Other supports or substrates include stone, ivory, silk, reed, papyrus, bark papers, plastics, vellum, leather, fabric, wood, and watercolor canvas (coated with a gesso that is specially formulated for use with watercolors). Watercolor paper is often made entirely or partially with cotton. This gives the surface the appropriate texture and minimizes distortion when wet. Watercolor papers are usually cold-pressed papers that provide better texture and appearance. Another variation is hot-pressed watercolor paper, which has a smoother texture and appearance than cold-pressed paper. Transparency is the main characteristic of watercolors. It is caused by the gum binder being absorbed by the paper, leaving a top layer of dispersed pigment particles, through which the paper shimmers. "It consists of a mixture of pigments, binders such as gum arabic and humectants such as glycerin, which together with other components, allow the color pigment to join and form the paint paste, which we know as watercolor. With regard to the colors, the quality of the pigments and their degree of concentration, it is what determines how good the watercolor is and also its price. A paint that has a high concentration of pigment, professional type, allows us to use it with a large amount of water without losing the intensity of color." Watercolors can also be made opaque by adding Chinese white. In the 19th century this could be controversial, and not regarded as "true watercolor" in the English tradition, but by about 1880 this dispute was over. (Full article...)

The nude, as a form of visual art that focuses on the unclothed human figure, is an enduring tradition in Western art. It was a preoccupation of Ancient Greek art, and after a semi-dormant period in the Middle Ages returned to a central position with the Renaissance. Unclothed figures often also play a part in other types of art, such as history painting, including allegorical and religious art, portraiture, or the decorative arts. From prehistory to the earliest civilizations, nude female figures were generally understood to be symbols of fertility or well-being.

In India, the Khajuraho Group of Monuments built between 950 and 1050 CE are known for their nude sculptures, which comprise about 10% of the temple decorations, a minority of them being erotic. Japanese prints are one of the few non-western traditions that can be called nudes, but the activity of communal bathing in Japan is portrayed as just another social activity, without the significance placed upon the lack of clothing that exists in the West. Through each era, the nude has reflected changes in cultural attitudes regarding sexuality, gender roles, and social structure. (Full article...)

Genre painting (or petit genre) is the painting of genre art, which depicts aspects of everyday life by portraying ordinary people engaged in common activities. One common definition of a genre scene is that it shows figures to whom no identity can be attached either individually or collectively, thus distinguishing it from history paintings (also called grand genre) and portraits. A work would often be considered as a genre work even if it could be shown that the artist had used a known person—a member of his family, say—as a model. In this case it would depend on whether the work was likely to have been intended by the artist to be perceived as a portrait—sometimes a subjective question. The depictions can be realistic, imagined, or romanticized by the artist. Because of their familiar and frequently sentimental subject matter, genre paintings have often proven popular with the bourgeoisie, or middle class.

Genre subjects appear in many traditions of art. Painted decorations in ancient Egyptian tombs often depict banquets, recreation, and agrarian scenes, and Peiraikos is mentioned by Pliny the Elder as a Hellenistic panel painter of "low" subjects, such as survive in mosaic versions and provincial wall-paintings at Pompeii: "barbers' shops, cobblers' stalls, asses, eatables and similar subjects". Medieval illuminated manuscripts often illustrated scenes of everyday peasant life, especially in the Labours of the Months in the calendar section of books of hours, most famously the Très Riches Heures du Duc de Berry.

Orange peel is a certain kind of finish that may develop on painted and cast surfaces. The texture resembles the surface of the skin of an orange, hence the name "orange peel".

Gloss paint sprayed on a smooth surface (such as the body of a car) should also dry into a smooth surface. However, various factors can cause it to dry into a bumpy surface. This is typically the result of improper painting technique, and is caused by the quick evaporation of thinner, incorrect spray gun setup (e.g., low air pressure or incorrect nozzle), spraying the paint at an angle other than perpendicular, or applying excessive paint.

A combine painting or Combine is an artwork that incorporates elements of both painting and sculpture. Items attached to paintings might include three-dimensional everyday objects such as clothing or furniture, as well as printed matter including photographs or newspaper clippings.

The term is most closely associated with the artwork of American artist Robert Rauschenberg (1925–2008) who coined the phrase Combine to describe his own artworks that explore the boundary between art and the everyday world. By placing them in the context of art, he endowed a new significance to ordinary objects. These cross-medium creations challenged the doctrine of medium specificity mentioned by modernist art critic Clement Greenberg. (Full article...)

The Boston school was a group of Boston-based painters active in the first three decades of the twentieth century. Often classified as American Impressionists, they had their own regional style, combining the painterliness of Impressionism with a more conservative approach to figure painting and a marked respect for the traditions of Western art history. Their preferred subject matter was genteel: portraits, picturesque landscapes, and young women posing in well-appointed interiors. Major influences included John Singer Sargent, Claude Monet, and Jan Vermeer. Key figures in the Boston school were Edmund C. Tarbell, Frank Weston Benson, and William McGregor Paxton, all of whom trained in Paris at the Académie Julian and later taught at the School of the Museum of Fine Arts. Their influence can still be seen in the work of some contemporary Boston-area artists. (Full article...)

A binder or binding agent is any material or substance that holds or draws other materials together to form a cohesive whole mechanically, chemically, by adhesion or cohesion.

More narrowly, binders are liquid or dough-like substances that harden by a chemical or physical process and bind fibres, filler powder and other particles added into it. Examples include glue, adhesive and thickening. (Full article...)

The ISCC–NBS System of Color Designation is a system for naming colors based on a set of 13 basic color terms and a small set of adjective modifiers. It was first established in the 1930s by a joint effort of the Inter-Society Color Council (ISCC), made up of delegates from various American trade organizations, and the National Bureau of Standards (NBS), a US government agency. As suggested in 1932 by the first chairman of the ISCC, the system's goal is to be "a means of designating colors in the United States Pharmacopoeia, in the National Formulary, and in general literature ... such designation to be sufficiently standardized as to be acceptable and usable by science, sufficiently broad to be appreciated and used by science, art, and industry, and sufficiently commonplace to be understood, at least in a general way, by the whole public." The system aims to provide a basis on which color definitions in fields from fashion and printing to botany and geology can be systematized and regularized, so that each industry need not invent its own incompatible color system.

In 1939, the system's approach was published in the Journal of Research of the National Bureau of Standards, and the ISCC formally approved the system, which consisted of a set of blocks within the color space defined by the Munsell color system as embodied by the Munsell Book of Color. Over the following decades, the ISCC–NBS system's boundaries were tweaked and its relation to various other color standards were defined, including for instance those for plastics, building materials, botany, paint, and soil.

In painting, local color is the color of an object when seen under flat white light with no adjustment for form shadow or colors of light or secondary light sources. An example would be the assumption that an apple is "red" when it is actually dependent on the color of the light hitting it, color of objects around it, glossiness, and variations within the colors on the surface of the apple itself. Local color is learned in childhood to help simplify and make sense of the world. "The sky is blue", "grass is green", etc. when there are actually myriad variations in hue, chroma, within these areas. In order to represent objects realistically, painters must look beyond the simplifications of local color. Demonstrations of color constancy show how flawed local color assumptions can be when the light source has a color shift.

In contemporary sculpture local color is the original color of the raw material that remains unpainted in the completed work. (Full article...)

In art, a pendant is one of two paintings, statues, reliefs or other type of works of art intended as a pair. Typically, pendants are related thematically to each other and are displayed in close proximity. For example, pairs of portraits of married couples are very common, as are symmetrically arranged statues flanking an altar.

Diptych differs from a pendant in that two images, reliefs, etc., are connected by hinges or similar means and cannot be separated. (Full article...)

A cabinet painting (or cabinet picture) is a small painting, typically no larger than two feet (0.61 meters) in either dimension, but often much smaller. The term is especially used for paintings that show full-length figures or landscapes at a small scale, rather than a head or other object painted nearly life-size. Such paintings are done very precisely, with a great degree of "finish".

From the fifteenth century onward, wealthy collectors of art would keep these paintings in a cabinet, which was a relatively small and private room (often very small even in large houses) to which only those with whom they were on especially intimate terms would be admitted. A cabinet, also known as a closet, study (from the Italian studiolo), office, or by other names, might be used as an office or just a sitting room. Heating the main rooms in large palaces or mansions in the winter was difficult, so small rooms such as cabinets were more comfortable. They offered more privacy from servants or other household members and visitors. Typically, a cabinet would be for the use of a single individual; a large house might have at least two (his and hers) and often more. (Full article...)

A mural is any piece of graphic artwork that is painted or applied directly to a wall, ceiling or other permanent substrate. Mural techniques include fresco, mosaic, graffiti and marouflage. (Full article...)

The lining of paintings is a process of conservation science and art restoration used to strengthen, flatten or consolidate oil or tempera paintings on canvas by attaching a new support to the back of the existing one. The process is sometimes referred to as relining. Most often a new support will be added directly to the back of an existing canvas. In cases of extreme decay, however, the original canvas may be completely removed and replaced. The height of the practice's use peaked in the late 19th century and in the following years its usefulness has been debated. There are many different factors that influence whether lining a painting will be successful. By paying close attention to an artwork's condition and response to treatment, conservation professionals better understand the lining process and when to apply it. (Full article...)

Shaped canvases are paintings that depart from the normal flat, rectangular configuration. Canvases may be shaped by altering their outline, while retaining their flatness. An ancient, traditional example is the tondo, a painting on a round panel or canvas: Raphael, as well as some other Renaissance painters, sometimes chose this format for madonna paintings. Alternatively, canvases may be altered by losing their flatness and assuming a three-dimensional surface. Or they can do both. That is, they can assume shapes other than rectangles, and also have surface features that are three-dimensional. Arguably, changing the surface configuration of the painting transforms it into a sculpture. But shaped canvases are generally considered paintings.

Apart from any aesthetic considerations, there are technical matters, having to do with the very nature of canvas as a material, that tend to support the flat rectangle as the norm for paintings on canvas. (Full article...)

Illusionism in art history means either the tradition of art that appears to share the physical space with the viewer or more broadly the attempt to represent physical appearances precisely – also called mimesis. The latter can also be called realism, but the term can also mean the use of everyday subject-matter, or the avoidance of idealizing subjects. Illusionism encompasses a long history, from the deceptions of Zeuxis and Parrhasius to the works of muralist Richard Haas in the twentieth century, that includes trompe-l'œil, anamorphosis, optical art, abstract illusionism, and illusionistic ceiling painting techniques such as di sotto in sù and quadratura. Sculptural illusionism includes works, often painted, that appear real from a distance. Other forms, such as the illusionistic tradition in the theatre, and Samuel van Hoogstraten's "peepshow"-boxes from the seventeenth century, combine illusionistic techniques and media.

Underdrawing is a preparatory drawing done on a painting ground before paint is applied, for example, an imprimatura or an underpainting. Underdrawing was used extensively by 15th century painters like Jan van Eyck and Rogier van der Weyden. These artists "underdrew" with a brush, using hatching strokes for shading, using water-based black paint, before underpainting and overpainting with oils. Cennino D'Andrea Cennini (14th century most likely) describes a different type of underdrawing, made with graded tones rather than hatching, for egg tempera.

In some cases, underdrawing can be clearly visualized using infrared reflectography because carbon black pigments absorb infrared light, whereas opaque pigments such as lead white are transparent with infrared light. Underdrawing in many works, for example, the Annunciation (van Eyck, Washington) or the Arnolfini Portrait, reveals that artists made pentimenti or alterations, sometimes radical ones, to their compositions.

Painting is a visual art, characterized by the practice of applying paint, pigment, color or other medium to a solid surface. The medium is commonly applied to the base with a brush. Other implements, such as palette knives, sponges, airbrushes, the artist's fingers, or even a dripping technique that uses gravity may be used. One who produces paintings is called a painter.

In art, the term "painting" describes both the act and the result of the action (the final work is called "a painting"). The support for paintings includes such surfaces as walls, paper, canvas, wood, glass, lacquer, pottery, leaf, copper and concrete; the painting may incorporate other materials, in single or multiple form, including sand, clay, paper, cardboard, newspaper, plaster, gold leaf, and even entire objects.

Cangiante (Italian: [kanˈdʒante]) is a painting technique where, when using relatively pure colors, one changes to a different, inherently-darker color to show shading, instead of dulling the original color by darkening it with black or a darker related hue. According to the theory of the art historian Marcia B. Hall, which has gained considerable acceptance, this is one of the canonical painting modes of the Renaissance; i.e. one of the four modes of painting colours available to Italian High Renaissance painters, along with sfumato, chiaroscuro and unione. The word itself is the present participle of the Italian verb cangiare ("to change"). This approach to the use of color is sometimes referred to as "cangiantismo".

Cangiante is characterized by a change in color when a painted object changes from light to dark (value) due to variations in illumination (light and shadow). For example, when in a painting an object appears yellow in its illuminated area, the artist may use a red color for attached shadows rather than transition to the dark, less colorful, forms of yellow, i.e. yellow-brown, raw umber. There are other methods of rendering shadows (for example, mixing the original hue with black or brown), but these can render the shadow color dull and impure. During the Renaissance, the variety and availability of paint colors were severely limited. (Full article...)

Illusionistic ceiling painting, which includes the techniques of perspective di sotto in sù and quadratura, is the tradition in Renaissance, Baroque and Rococo art in which trompe-l'œil, perspective tools such as foreshortening, and other spatial effects are used to create the illusion of three-dimensional space on an otherwise two-dimensional or mostly flat ceiling surface above the viewer. It is frequently used to create the illusion of an open sky, such as with the oculus in Andrea Mantegna's Camera degli Sposi, or the illusion of an architectural space such as the cupola, one of Andrea Pozzo's frescoes in Sant'Ignazio, Rome. Illusionistic ceiling painting belongs to the general class of illusionism in art, designed to create accurate representations of reality, as well as the general class of painted ceilings.

Paint by number or painting by numbers kits are self-contained painting sets, designed to facilitate painting a pre-designed image. They generally include brushes, tubs of paint with numbered labels, and a canvas printed with borders and numbers. The user selects the color corresponding to one of the numbers then uses it to fill in a delineated section of the canvas, in a manner similar to a coloring book.

The kits were invented, developed and marketed in 1950 by Max S. Klein, an engineer and owner of the Palmer Paint Company in Detroit, Michigan, United States, and Dan Robbins, a commercial artist. When Palmer Paint introduced crayons to consumers, they also posted images online for a "Crayon by Number" version. (Full article...)

Gongbi (simplified Chinese: 工笔; traditional Chinese: 工筆; pinyin: gōng bǐ; Wade–Giles: kung-pi) is a careful realist technique in Chinese painting, the opposite of the interpretive and freely expressive xieyi (寫意 'sketching thoughts') style.

The name is from the Chinese gong jin meaning 'tidy' (meticulous brush craftsmanship). The gongbi technique uses highly detailed brushstrokes that delimits details very precisely and without independent or expressive variation. It is often highly colored and usually depicts figural or narrative subjects. (Full article...)

Fresco-secco (or a secco or fresco finto) is a wall painting technique where pigments mixed with an organic binder and/or lime are applied onto dry plaster. The paints used can e.g. be casein paint, tempera, oil paint, silicate mineral paint. If the pigments are mixed with lime water or lime milk and applied to a dry plaster the technique is called lime secco painting.
The secco technique contrasts with the fresco technique, where the painting is executed on a layer of wet plaster.

Because the pigments do not become part of the wall, as in buon fresco, fresco-secco paintings are less durable. The colors may flake off the painting as time goes by, but this technique has the advantages of a longer working time and retouchability. In Italy, the fresco technique was reintroduced around 1300 and led to an increase in the general quality of mural painting. This technological change coincided with the realistic turn in Western art and the changing liturgical use of murals. (Full article...)

China painting, or porcelain painting, is the decoration of glazed porcelain objects, such as plates, bowls, vases or statues. The body of the object may be hard-paste porcelain, developed in China in the 7th or 8th century, or soft-paste porcelain (often bone china), developed in 18th-century Europe. The broader term ceramic painting includes painted decoration on lead-glazed earthenware such as creamware or tin-glazed pottery such as maiolica or faience.

Typically the body is first fired in a kiln to convert it into a hard porous biscuit or bisque. Underglaze decoration may then be applied, followed by glaze, which is fired so it bonds to the body. The glazed porcelain may then be painted with overglaze decoration and fired again to bond the paint with the glaze. Most pieces use only one of underglaze or overglaze painting, the latter often being referred to as "enamelled". Decorations may be applied by brush or by stenciling, transfer printing and screen printing. (Full article...)

Cobweb painting, sometimes known as gossamer painting, is the delicate process of painting on canvases made from caterpillar and spider webs that have been collected, layered, cleaned, and framed. The fragile works of art on thin, translucent surfaces was practiced primarily in South Tyrol in the 18th and early 19th centuries. Fewer than 100 cobweb paintings are known to exist, many of which are housed in collections. (Full article...)

Quadro riportato (plural quadri riportati) is the Italian phrase for "carried picture" or "transported paintings". It is used in art to describe gold-framed easel paintings or framed paintings that are seen in a normal perspective and painted into a fresco. The final effect is similar to illusionism, but the latter encompasses painted statues, reliefs and tapestries.

The ceiling is intended to look as if a framed painting has been placed overhead; there is no illusionistic foreshortening, figures appearing as if they were to be viewed at normal eye level. Mengs' Parnassus (1761) in the Villa Albani (now Villa Albani-Torlonia) is a famous example — a Neoclassical criticism against Baroque illusionism. Often, however, quadri riportati were combined with illusionistic elements, as in Annibale Carracci's Farnese Ceiling (1597–1600) in Rome. (Full article...)

Pointillism (/ˈpwæ̃tɪlɪzəm/, also US: /ˈpwɑːn-ˌ ˈpɔɪn-/) is a technique of painting in which small, distinct dots of color are applied in patterns to form an image.

Georges Seurat and Paul Signac developed the technique in 1886, branching from Impressionism. The term "Pointillism" was coined by art critics in the late 1880s to ridicule the works of these artists, but is now used without its earlier pejorative connotation. The movement Seurat began with this technique is known as Neo-impressionism. The Divisionists used a similar technique of patterns to form images, though with larger cube-like brushstrokes.

Maki-e (蒔絵, literally: sprinkled picture (or design)) is a Japanese lacquer decoration technique in which pictures, patterns, and letters are drawn with lacquer on the surface of lacquerware, and then metal powder such as gold or silver is sprinkled and fixed on the surface of the lacquerware. The origin of the term maki-e is a compound word of maki meaning "sprinkling" and e meaning "picture" or "design". The term can also be used to refer to lacquerware made with this decorative technique. The term maki-e first appeared in the Heian period.

This technique is the most used technique in Japanese lacquer decoration. The maki-e is often combined with other techniques such as raden (螺鈿) in which a nacreous layer of mollusk shell lining is embedded or pasted in lacquer, zōgan (象嵌) in which metal or ivory is embedded in lacquer, and chinkin (沈金) in which gold leaf or gold powder is embedded in a hollow where lacquer has been shaved.

An airbrush is a small, air-operated tool that atomizes and sprays various media, most often paint, but also ink, dye, and make-up. Spray painting developed from the airbrush and is considered to employ a type of airbrush. (Full article...)

Mineral painting or Keim's process, also known as stereochromy, is a mural or fresco painting technique that uses a water glass-based paint to maximize the lifetime of the finished work.

The name "stereochromy" was first used in about 1825 by Johann Nepomuk von Fuchs and Schlotthaurer. In the original technique, pigments were applied to plaster or stone and sealed with water glass to preserve and enhance the colors. The method was then improved in the 1880s by Adolf Wilhelm Keim and renamed mineral painting or Keim's process. (Full article...)

Fat over lean refers to the principle in oil painting of applying paint with a higher oil to pigment ratio ('fat') over paint with a lower oil to pigment ratio ('lean') to ensure a stable paint film, since it is believed that the paint with the higher oil content remains more flexible.

Oil paint dries at different rates due to the differing drying properties of the constituent pigment. However, everything else being equal, the higher the oil to pigment ratio, the longer the oil binder will take to oxidize, and the more flexible the paint film will be. Conversely, the lower the oil content, the faster the paint dries, and the more brittle it will be. Ignoring this practice, even in some alla prima painting, may result in a cracked and less durable paint film. (Full article...)

A fore-edge painting is an image painted on the unbound edges of a book visible when the pages of the book are fanned. It also can refer to an image that is visible on the closed edge of a book. References also refer to the paintings as disappearing or secret images, and they are often hidden beneath gilded edges.

Historically, fore-edge painting has had three purposes: identification, indication of ownership, or artistry. Possibly originating in the 10th century, the earliest known examples feature titles written on the closed edges of a book, symbolic imagery, or heraldic designs. The exact origins are debated among scholars. The technique of the hidden painting gained notable popularity in England during the 17th and 18th centuries. A fore-edge painting does not need to be painted on a book at the time of the book's creation. Unless a fore-edge artist was working with a bookseller or bookbinder, fore-edge paintings are applied sometime after the book has been published making the dating of the works difficult to ascertain unless the work is signed and dated.

Craquelure (French: craquelure; Italian: crettatura) is a fine pattern of dense cracking formed on the surface of materials. It can be a result of drying, shock, aging, intentional patterning, or a combination of all four. The term is most often used to refer to tempera or oil paintings, but it can also develop in old ivory carvings or painted miniatures on an ivory backing. Recently, analysis of craquelure has been proposed as a way to authenticate art.

In ceramics, craquelure in ceramic glazes, where it is often a desired effect, is called "crackle"; it is a characteristic of Chinese Ge ware in particular. This is usually differentiated from crazing, which is a glaze defect in firing, or the result of aging or damage. (Full article...)

In painting, imprimatura is an initial stain of color painted on a ground. It provides a painter with a transparent, toned ground, which will allow light falling onto the painting to reflect through the paint layers. The term comes from Italian and literally means 'first paint layer'. Its use as an underpainting layer can be dated back to the guilds and workshops during the Middle Ages; however, it came into standard use by painters during the Renaissance, particularly in Italy.

The imprimatura not only provides an overall tonal optical unity in a painting but is also useful in the initial stages of the work because it helps the painter establish value relations from dark to light. It is most useful in the classical approach of indirect painting, in which the drawing and underpainting are established ahead of time and allowed to dry. The successive layers of color are then applied in transparent glaze or semi-transparent layers. (Full article...)

Microbial art, agar art, or germ art is artwork created by culturing microorganisms in certain patterns. The microbes used can be bacteria, yeast, fungi, or less commonly, protists. The microbes can be chosen for their natural colours or engineered to express fluorescent proteins and viewed under ultraviolet light to make them fluoresce in colour. (Full article...)

An oil sketch or oil study is an artwork made primarily in oil paint in preparation for a larger, finished work. Originally these were created as preparatory studies or modelli, especially so as to gain approval for the design of a larger commissioned painting. They were also used as designs for specialists in other media, such as printmaking or tapestry, to follow. Later they were produced as independent works, often with no thought of being expanded into a full-size painting.

The usual medium for modelli was the drawing, but an oil sketch, even if done in a limited range of colours, could better suggest the tone of the projected work. It is also possible to more fully convey the flow and energy of a composition in paint. For a painter with exceptional technique, the production of an oil sketch may be as rapid as that of a drawing, and many practitioners had superb brush skills. In its rapidity of execution the oil sketch may be used not only to express movement and transient effects of light and color, its gestural nature may even represent a mimetic parallel to the action of the subject.

Ceramic glaze, or simply glaze, is a glassy coating on ceramics. It is used for decoration, to ensure the item is impermeable to liquids and to minimize the adherence of pollutants.

Glazing renders earthenware impermeable to water, sealing the inherent porosity of earthenware. It also gives a tougher surface. Glaze is also used on stoneware and porcelain. In addition to their functionality, glazes can form a variety of surface finishes, including degrees of glossy or matte finish and color. Glazes may also enhance the underlying design or texture either unmodified or inscribed, carved or painted. (Full article...)
