Porcelain is a ceramic material made by heating raw materials, generally including kaolinite, in a kiln to temperatures between 1,200 and 1,400 °C. The greater strength and translucence of porcelain, relative to other types of pottery, arise mainly from vitrification and the formation of the mineral mullite within the body at these high temperatures. End applications include tableware, decorative ware such as figurines, and products in technology and industry such as electrical insulators and laboratory ware.
Longquan celadon is a type of green-glazed Chinese ceramic, known in the West as celadon or greenware, produced from about 950 to 1550. The kilns were mostly in Lishui prefecture in southwestern Zhejiang Province in the south of China, and the north of Fujian Province. Overall a total of some 500 kilns have been discovered, making the Longquan celadon production area one of the largest historical ceramic producing areas in China. "Longquan-type" is increasingly preferred as a term, in recognition of this diversity, or simply "southern celadon", as there was also a large number of kilns in north China producing Yaozhou ware or other Northern Celadon wares. These are similar in many respects, but with significant differences to Longquan-type celadon, and their production rose and declined somewhat earlier.
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.
"Blue and white pottery" covers a wide range of white pottery and porcelain decorated under the glaze with a blue pigment, generally cobalt oxide. The decoration was commonly applied by hand, originally by brush painting, but nowadays by stencilling or by transfer-printing, though other methods of application have also been used. The cobalt pigment is one of the very few that can withstand the highest firing temperatures that are required, in particular for porcelain, which partly accounts for its long-lasting popularity. Historically, many other colours required overglaze decoration and then a second firing at a lower temperature to fix that.
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."
Chinese ceramics are one of the most significant forms of Chinese art and ceramics globally. They 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.
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).
Shiwan ware is Chinese pottery from kilns located in the Shiwanzhen Subdistrict of the provincial city of Foshan, near Guangzhou, Guangdong. It forms part of a larger group of wares from the coastal region known collectively as "Canton stonewares". The hilly, wooded, area provided slopes for dragon kilns to run up, and fuel for them, and was near major ports.
Tongzhi porcelain is Chinese porcelain from the reign of the Qing dynasty Tongzhi Emperor (1862–1874), which saw the reconstruction of the Jingdezhen official kilns after the Taiping Rebellion of the 1850s completely devastated the cities of Nanjing and Jingdezhen.
Jingdezhen porcelain is Chinese porcelain produced in or near Jingdezhen in Jiangxi province in southern China. Jingdezhen may have produced pottery as early as the sixth century CE, though it is named after the reign name of Emperor Zhenzong, in whose reign it became a major kiln site, around 1004. By the 14th century it had become the largest centre of production of Chinese porcelain, which it has remained, increasing its dominance in subsequent centuries. From the Ming period onwards, official kilns in Jingdezhen were controlled by the emperor, making imperial porcelain in large quantity for the court and the emperor to give as gifts.
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.
Guan ware or Kuan ware is one of the Five Famous Kilns of Song dynasty China, making high-status stonewares, whose surface decoration relied heavily on crackled glaze, randomly crazed by a network of crack lines in the glaze.
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, 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.
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.
The Five Great Kilns, also known as Five Famous Kilns, is a generic term for ceramic kilns or wares which produced Chinese ceramics during the Song dynasty (960–1279) that were later held in particularly high esteem. The group were only so called by much later writers, and of the five, only two seem to have produced wares directly ordered by the Imperial court, though all can be of very high quality. All were imitated later, often with considerable success.
Ru ware, Ju ware, or "Ru official ware" is a famous and extremely rare type of Chinese pottery from the Song dynasty, produced for the imperial court for a brief period around 1100. Fewer than 100 complete pieces survive, though there are later imitations which do not entirely match the originals. Most have a distinctive pale "duck-egg" blue glaze, "like the blue of the sky in a clearing amongst the clouds after rain" according to a medieval connoisseur, and are otherwise undecorated, though their colours vary and reach into a celadon green. The shapes include dishes, probably used as brush-washers, cups, wine bottles, small vases, and censers and incense-burners. They can be considered as a particular form of celadon wares.
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.
Ge ware or Ko ware is a type of celadon or greenware in Chinese pottery. It was one of the Five Great Kilns of the Song dynasty recognised by later Chinese writers, but has remained rather mysterious to modern scholars, with much debate as to which surviving pieces, if any, actually are Ge ware, whether they actually come from the Song, and where they were made. In recognition of this, many sources call all actual pieces Ge-type ware.
A dragon kiln or "climbing kiln", is a traditional Chinese form of kiln, used for Chinese ceramics, especially in southern China. It is long and thin, and relies on having a fairly steep slope, typically between 10° and 16°, up which the kiln runs. The kiln could achieve the very high temperatures, sometimes as high as 1400 °C, necessary for high-fired wares including stoneware and porcelain, which long challenged European potters, and some examples were very large, up to 60 metres long, allowing up to 25,000 pieces to be fired at a time. By the early 12th century CE they might be over 135 metres long, allowing still larger quantities to be fired; more than 100,000 have been claimed.
Sang de boeuf glaze, or sang-de-boeuf, is a deep red colour of ceramic glaze, first appearing in Chinese porcelain at the start of the 18th century. The name is French, meaning "ox blood", and the glaze and the colour sang de boeuf are also called ox-blood or oxblood in English, in this and other contexts.
