Pottery is the process and the products of forming vessels and other objects with clay and other raw materials, which are fired at high temperatures to give them a hard and durable form. The place where such wares are made by a potter is also called a pottery. The definition of pottery, used by the ASTM International, is "all fired ceramic wares that contain clay when formed, except technical, structural, and refractory products". End applications include tableware, decorative ware, sanitaryware, and in technology and industry such as electrical insulators and laboratory ware. In art history and archaeology, especially of ancient and prehistoric periods, pottery often means vessels only, and sculpted figurines of the same material are called terracottas.
Celadon is a term for pottery denoting both wares glazed in the jade green celadon color, also known as greenware or "green ware", and a type of transparent glaze, often with small cracks, that was first used on greenware, but later used on other porcelains. Celadon originated in China, though the term is purely European, and notable kilns such as the Longquan kiln in Zhejiang province are renowned for their celadon glazes. Celadon production later spread to other parts of East Asia, such as Japan and Korea, as well as Southeast Asian countries, such as Thailand. Eventually, European potteries produced some pieces, but it was never a major element there. Finer pieces are in porcelain, but both the color and the glaze can be produced in stoneware and earthenware. Most of the earlier Longquan celadon is on the border of stoneware and porcelain, meeting the Chinese but not the European definitions of porcelain.
Slipware is pottery identified by its primary decorating process where slip is placed onto the leather-hard (semi-hardened) clay body surface before firing by dipping, painting or splashing. Slip is an aqueous suspension of a clay body, which is a mixture of clays and other minerals such as quartz, feldspar and mica. The slip placed onto a wet or leather-hard clay body surface by a variety of techniques including dipping, painting, piping or splashing. Slipware is the pottery on which slip has been applied either for glazing or decoration. Slip is liquified clay or clay slurry, with no fixed ratio of water and clay, which is used either for joining pottery pieces together by slip casting with mould, glazing or decorating the pottery by painting or dipping the pottery with slip.
Lustreware or lusterware is a type of pottery or porcelain with a metallic glaze that gives the effect of iridescence. It is produced by metallic oxides in an overglaze finish, which is given a second firing at a lower temperature in a "muffle kiln", or a reduction kiln, excluding oxygen.
Islamic pottery occupied a geographical position between Chinese ceramics, and the pottery of the Byzantine Empire and Europe. For most of the period, it made great aesthetic achievements and influence as well, influencing Byzantium and Europe. The use of drinking and eating vessels in gold and silver, the ideal in ancient Rome and Persia as well as medieval Christian societies, is prohibited by the Hadiths, with the result that pottery and glass were used for tableware by Muslim elites, as pottery also was in China but was much rarer in Europe and Byzantium. In the same way, Islamic restrictions greatly discouraged figurative wall painting, encouraging the architectural use of schemes of decorative and often geometrically patterned titles, which are the most distinctive and original specialty of Islamic ceramics.
Slip casting, or slipcasting, is a ceramic forming technique, and is widely used by commercial industry as well as contemporary fine artists as a way of making various ceramic forms. This technique is suitable for simple functional objects such as cups and plates, as well as more complicated shapes like figurative ceramics that would be difficult to be reproduced by hand or other forming techniques. The technique involves a clay body slip which is essentially a liquid version of clay, usually prepared in a blunger, being poured into plaster moulds and allowed to form a layer, the cast, on the internal walls of the mould.
Ding ware, Ting ware or Dingyao are Chinese ceramics, mostly porcelain, that were produced in the prefecture of Dingzhou in Hebei in northern China. The main kilns were at Jiancicun or Jianci in Quyang County. They were produced between the Tang and Yuan dynasties of imperial China, though their finest period was in the 11th century, under the Northern Song. The kilns "were in almost constant operation from the early eighth until the mid-fourteenth century."
Barbotine is the French for ceramic slip, or a mixture of clay and water used for moulding or decorating pottery. In English the term is used for three different techniques of decorating pottery, though in all cases mainly for historical works. For clarity, these types are numbered here as A-C.
Chinese ceramics show a continuous development since pre-dynastic times and are one of the most significant forms of Chinese art and ceramics globally. The first pottery was made during the Palaeolithic era. Chinese ceramics range from construction materials such as bricks and tiles, to hand-built pottery vessels fired in bonfires or kilns, to the sophisticated Chinese porcelain wares made for the imperial court and for export. Porcelain was a Chinese invention and is so identified with China that it is still called "china" in everyday English usage.
Jun ware is a type of Chinese pottery, one of the Five Great Kilns of Song dynasty ceramics. Despite its fame, much about Jun ware remains unclear, and the subject of arguments among experts. Several different types of pottery are covered by the term, produced over several centuries and in several places, during the Northern Song dynasty (960–1127), Jin dynasty (1115–1234) and Yuan dynasty (1271–1368), and lasting into the early Ming dynasty (1368–1644).
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 minimise the adherence of pollutants.
Overglaze decoration, overglaze enamelling, or on-glaze decoration, is a method of decorating pottery, most often porcelain, where the coloured decoration is applied on top of the already fired and glazed surface, and then fixed in a second firing at a relatively low temperature, often in a muffle kiln. It is often described as producing "enamelled" decoration. The colours fuse on to the glaze, so the decoration becomes durable. This decorative firing is usually done at a lower temperature which allows for a more varied and vivid palette of colours, using pigments which will not colour correctly at the high temperature necessary to fire the porcelain body. Historically, a relatively narrow range of colours could be achieved with underglaze decoration, where the coloured pattern is applied before glazing, notably the cobalt blue of blue and white porcelain.
This is a list of pottery and ceramic terms.
Sancai is a versatile type of decoration on Chinese pottery using glazes or slip, predominantly in the three colours of brown, green, and a creamy off-white. It is particularly associated with the Tang dynasty (618–907) and its tomb figures, appearing around 700. Therefore, it is commonly referred to as Chinese: 唐三彩 Tang Sancai in Chinese. Tang sancai wares were sometimes referred in China and the West as egg-and-spinach by dealers, for their use of green, yellow, and white, especially when combined with a streaked effect.
Qingbai ware is a type of Chinese porcelain produced under the Song Dynasty and Yuan dynasty, defined by the ceramic glaze used. Qingbai ware is white with a blue-greenish tint, and is also referred to as Yingqing. It was made in Jiangxi province in south-eastern China, in several locations including Jingdezhen, and is arguably the first type of porcelain to be produced on a very large scale. However, it was not at the time a prestigious ware, and was mostly used for burial wares and exports, or a middle-rank Chinese market. The quality is very variable, reflecting these different markets; the best pieces can be very thin-walled.
Chinese influences on Islamic pottery cover a period starting from at least the 8th century CE to the 19th century. This influence of Chinese ceramics has to be viewed in the broader context of the considerable importance of Chinese culture on Islamic arts in general.
Cizhou ware or Tz'u-chou ware is a wide range of Chinese ceramics from between the late Tang dynasty and the early Ming dynasty, but especially associated with the Northern Song to Yuan period in the 11–14th century. It has been increasingly realized that a very large number of sites in northern China produced these wares, and their decoration is very variable, but most characteristically uses black and white, in a variety of techniques. For this reason Cizhou-type is often preferred as a general term. All are stoneware in Western terms, and "high-fired" or porcelain in Chinese terms. They were less high-status than other types such as celadons and Jun ware, and are regarded as "popular", though many are finely and carefully decorated.
Ceramic art is art made from ceramic materials, including clay. It may take varied forms, including artistic pottery, including tableware, tiles, figurines and other sculpture. As one of the plastic arts, ceramic art is a visual art. While some ceramics are considered fine art, such as pottery or sculpture, most are considered to be decorative, industrial or applied art objects. Ceramic art can be created by one person or by a group, in a pottery or a ceramic factory with a group designing and manufacturing the artware.
Jizhou ware or Chi-chou ware is Chinese pottery from Jiangxi province in southern China; the Jizhou kilns made a number of different types of wares over the five centuries of production. The best known wares are simple shapes in stoneware, with a strong emphasis on subtle effects in the dark glazes, comparable to Jian ware, but often combined with other decorative effects. In the Song dynasty they achieved a high prestige, especially among Buddhist monks and in relation to tea-drinking. The wares often use leaves or paper cutouts to create resist patterns in the glaze, by leaving parts of the body untouched.
Yaozhou ware is a type of celadon or greenware in Chinese pottery, which was at its height during the Northern Song dynasty. It is the largest and typically the best of the wares in the group of Northern Celadon wares. It is especially famous for the rich effects achieved by decoration in shallow carving under a green celadon glaze which sinks into the depressions of the carving giving contrasts of light and dark shades.
