Longquan celadon (龍泉青瓷) 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.
Earthenware is glazed or unglazed nonvitreous pottery that has normally been fired below 1,200 °C (2,190 °F). Basic earthenware, often called terracotta, absorbs liquids such as water. However, earthenware can be made impervious to liquids by coating it with a ceramic glaze, which the great majority of modern domestic earthenware has. The main other important types of pottery are porcelain, bone china, and stoneware, all fired at high enough temperatures to vitrify.
Faience or faïence is the general English language term for fine tin-glazed pottery. The invention of a white pottery glaze suitable for painted decoration, by the addition of an oxide of tin to the slip of a lead glaze, was a major advance in the history of pottery. The invention seems to have been made in Iran or the Middle East before the ninth century. A kiln capable of producing temperatures exceeding 1,000 °C (1,830 °F) was required to achieve this result, the result of millennia of refined pottery-making traditions. The term is now used for a wide variety of pottery from several parts of the world, including many types of European painted wares, often produced as cheaper versions of porcelain styles.
Stoneware is a rather broad term for pottery or other ceramics fired at a relatively high temperature. A modern technical definition is a vitreous or semi-vitreous ceramic made primarily from stoneware clay or non-refractory fire clay. Whether vitrified or not, it is nonporous ; it may or may not be glazed. Historically, around the world, it has been developed after earthenware and before porcelain, and has often been used for high-quality as well as utilitarian wares.
Pottery and porcelain, is one of the oldest Japanese crafts and art forms, dating back to the Neolithic period. Kilns have produced earthenware, pottery, stoneware, glazed pottery, glazed stoneware, porcelain, and blue-and-white ware. Japan has an exceptionally long and successful history of ceramic production. Earthenwares were created as early as the Jōmon period, giving Japan one of the oldest ceramic traditions in the world. Japan is further distinguished by the unusual esteem that ceramics holds within its artistic tradition, owing to the enduring popularity of the tea ceremony.
Salt-glaze or salt glaze pottery is pottery, usually stoneware, with a glaze of glossy, translucent and slightly orange-peel-like texture which was formed by throwing common salt into the kiln during the higher temperature part of the firing process. Sodium from the salt reacts with silica in the clay body to form a glassy coating of sodium silicate. The glaze may be colourless or may be coloured various shades of brown, blue, or purple.
Biscuit porcelain, bisque porcelain or bisque is unglazed, white porcelain treated as a final product, with a matte appearance and texture to the touch. It has been widely used in European pottery, mainly for sculptural and decorative objects that are not tableware and so do not need a glaze for protection.
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 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.
Ceramic glaze is an impervious layer or coating of a vitreous substance which has been fused to a pottery body through firing. Glaze can serve to color, decorate or waterproof an item. Glazing renders earthenware vessels suitable for holding liquids, sealing the inherent porosity of unglazed biscuit 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.
Tin-glazed pottery is earthenware covered in lead glaze with added tin oxide which is white, shiny and opaque ; usually this provides a background for brightly painted decoration. It has been important in Islamic and European pottery, but very little used in East Asia. The pottery body is usually made of red or buff-colored earthenware and the white glaze imitated Chinese porcelain. The decoration on tin-glazed pottery is usually applied to the unfired glaze surface by brush with metallic oxides, commonly cobalt oxide, copper oxide, iron oxide, manganese dioxide and antimony oxide. The makers of Italian tin-glazed pottery from the late Renaissance blended oxides to produce detailed and realistic polychrome paintings.
Art pottery is a term for pottery with artistic aspirations, made in relatively small quantities, mostly between about 1870 and 1930. Typically, sets of the usual tableware items are excluded from the term; instead the objects produced are mostly decorative vessels such as vases, jugs, bowls and the like which are sold singly. The term originated in the later 19th century, and is usually used only for pottery produced from that period onwards. It tends to be used for ceramics produced in factory conditions, but in relatively small quantities, using skilled workers, with at the least close supervision by a designer or some sort of artistic director. Studio pottery is a step up, supposed to be produced in even smaller quantities, with the hands-on participation of an artist-potter, who often performs all or most of the production stages. But the use of both terms can be elastic. Ceramic art is often a much wider term, covering all pottery that comes within the scope of art history, but "ceramic artist" is often used for hands-on artist potters in studio pottery.
John Dwight was an English ceramic manufacturer, who founded the Fulham Pottery in London and pioneered the production of stoneware in England.
Ironstone china, ironstone ware or most commonly just ironstone, is a type of vitreous pottery first made in the United Kingdom in the early 19th century. It is often classed as earthenware although in appearance and properties it is similar to fine stoneware. It was developed in the 19th century by potters in Staffordshire, England, as a cheaper, mass-produced alternative for porcelain.
Redware as a single word is a term for at least two types of pottery of the last few centuries, in Europe and North America. Red ware as two words is a term used for pottery, mostly by archaeologists, found in a very wide range of places. However, these distinct usages are not always adhered to, especially when referring to the many different types of pre-colonial red wares in the Americas, which may be called "redware".
The Fulham Pottery was founded in Fulham, London, by John Dwight in 1672, at the junction of New King's Road and Burlington Road, Fulham, not far from Putney Bridge. Dwight is the earliest clearly documented maker of stoneware in England, although immigrant Dutch or German potters were probably active several decades before. By 1690 there was a rival stoneware operation in Fulham, run by the Dutch Elers brothers, who after a few years went off to become important early figures in transforming the Staffordshire pottery industry.
Lead-glazed earthenware is one of the traditional types of earthenware with a ceramic glaze, which coats the ceramic biscuit body and renders it impervious to liquids, as terracotta itself is not. Plain lead glaze is shiny and transparent after firing. Coloured lead glazes are shiny and either translucent or opaque after firing. Three other traditional techniques are tin-glazed, which coats the ware with an opaque white glaze suited for overglaze brush-painted colored enamel designs; salt glaze pottery, also often stoneware; and the feldspathic glazes of Asian porcelain. Modern materials technology has invented new vitreous glazes that do not fall into these traditional categories.
Ceramic art is art made from ceramic materials, including clay. It may take forms including artistic pottery, including tableware, tiles, figurines and other sculpture. As one of the plastic arts, ceramic art is one of the visual arts. While some ceramics are considered fine art, such as pottery or sculpture, most are considered to be decorative, industrial or applied art objects. Ceramics may also be considered artefacts in archaeology. Ceramic art can be made by one person or by a group of people. In a pottery or ceramic factory, a group of people design, manufacture and decorate the art ware. Products from a pottery are sometimes referred to as "art pottery". In a one-person pottery studio, ceramists or potters produce studio pottery.
Leeds Pottery, also known as Hartley Greens & Co., is a pottery manufacturer founded around 1756 in Hunslet, just south of Leeds, England. It is best known for its creamware, which is often called Leedsware; it was the "most important rival" in this highly popular ware of Wedgwood, who had invented the improved version used from the 1760s on. Many pieces include openwork, made either by piercing solid parts, or "basketwork", weaving thin strips of clay together. Several other types of ware were produced, mostly earthenware but with some stoneware.
The original Castleford Pottery operated from c. 1793 to 1820 in Castleford in Yorkshire, England. It was owned by David Dunderdale, and is especially known for making "a smear-glazed, finely moulded, white stoneware". This included feldspar, giving it a degree of opacity unusual in a stoneware. The designs typically included relief elements, and edges of the main shape and the panels into which the body was divided were often highlighted with blue overglaze enamel. Most pieces were teapots or accompanying milk jugs, sugar bowls and slop bowls, and the shapes often derived from those used in contemporary silversmithing.
