Porcelain is a ceramic material made by heating substances, generally including materials such as kaolinite, in a kiln to temperatures between 1,200 and 1,400 °C. The strength, and translucence of porcelain, relative to other types of pottery, arises mainly from vitrification and formation of the mineral mullite within the body at these high temperatures. Though definitions vary, porcelain can be divided into three main categories: hard-paste, soft-paste and bone china. The category that an object belongs to depends on the composition of the paste used to make the body of the porcelain object and the firing conditions.
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.
Bone china is a type of porcelain that is composed of bone ash, feldspathic material, and kaolin. It has been defined as "ware with a translucent body" containing a minimum of 30% of phosphate derived from animal bone and calculated calcium phosphate. Bone china is the strongest of the porcelain or china ceramics, having very high mechanical and physical strength and chip resistance, and is known for its high levels of whiteness and translucency. Its high strength allows it to be produced in thinner cross-sections than other types of porcelain. Like stoneware it is vitrified, but is translucent due to differing mineral properties.
Transfer printing is a method of decorating pottery or other materials using an engraved copper or steel plate from which a monochrome print on paper is taken which is then transferred by pressing onto the ceramic piece. Pottery decorated using the technique is known as transferware or transfer ware.
Royal Worcester was established in 1751 and is believed to be the oldest or second oldest remaining English porcelain brand still in existence today. Part of the Portmeirion Group since 2009, Royal Worcester remains in the luxury tableware and giftware market, although production in Worcester itself has ended.
Mintons was a major company in Staffordshire pottery, "Europe's leading ceramic factory during the Victorian era", an independent business from 1793 to 1968. It was a leader in ceramic design, working in a number of different ceramic bodies, decorative techniques, and "a glorious pot-pourri of styles - Rococo shapes with Oriental motifs, Classical shapes with Medieval designs and Art Nouveau borders were among the many wonderful concoctions". As well as pottery vessels and sculptures, the firm was a leading manufacturer of tiles and other architectural ceramics, producing work for both the Houses of Parliament and United States Capitol.
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.
A slip is a clay slurry used to produce pottery and other ceramic wares. Liquified clay, in which there is no fixed ratio of water and clay, is called slip or clay slurry which is used either for joining leather-hard (semi-hardened) clay body together by slipcasting with mould, glazing or decorating the pottery by painting or dipping the pottery with slip. Pottery on which slip has been applied either for glazing or decoration is called the slipware.
Eileen Rose Busby was an American author and antiques expert who was featured on HGTV's Appraise It! show.
Henry George Sandon, MBE is an English antique expert, television personality, author and lecturer specialising in ceramics and is a notable authority on Royal Worcester porcelain. He was curator of the Dyson Perrins Museum for many years.
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 Sandon is a British expert and prolific author on ceramics and glass. He is best known as an expert on the BBC's Antiques Roadshow, which he joined in 1985.
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.
Roger Soame Jenyns, who usually wrote his name simply as Soame Jenyns was a British art historian, known as an expert on East Asian ceramics.

Shelley Potteries, situated in Staffordshire, was earlier known as Wileman & Co. which had also traded as The Foley Potteries. The first Shelley to join the company was Joseph Ball Shelley in 1862 and in 1896 his son Percy Shelley became the sole proprietor, after which it remained a Shelley family business until 1966 when it was taken over by Allied English Potteries. Its china and earthenware products were many and varied although the major output was table ware. In the late Victorian period the Art Nouveau style pottery and Intarsio ranges designed by art director Frederick Alfred Rhead were extremely popular but Shelley is probably best known for its fine bone china “Art Deco” ware of the inter-war years and post-war fashionable tea ware.
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.
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.
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.
