Soft-paste
Soft-paste porcelain (sometimes simply "soft paste", or "artificial porcelain") is a type of ceramic material in pottery, usually accepted as a type of porcelain. It is weaker than "true" hard-paste porcelain, and does not require either the high firing temperatures or the special mineral ingredients needed for that. There are many types, using a range of materials. The material originated in the attempts by many European potters to replicate hard-paste Chinese export porcelain, especially in the 18th century, and the best versions match hard-paste in whiteness and translucency, but not in strength. But the look and feel of the material can be highly attractive, and it can take painted decoration very well. The ingredients varied considerably, but always included clay, often ball clay, and often ground glass, bone ash, soapstone (steatite), flint, and quartz. They rarely included the key ingredients necessary for hard-paste, china clay including kaolin, or the English china stone, ...

Porcelain
Porcelain () is a ceramic material made by heating substances, generally including materials such as kaolinite, in a kiln to temperatures between . 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. Porcelain slowly evolved in China and was finally achieved (depending on the definition used) at some point about 2,000 to 1,200 years ago; it slowly spread to other East Asian countries, then to Europe, and eventually to the rest of the world. Its manufacturing process is more demanding than that for earthenware and stoneware, the two other main types of pottery, an ...

Hard-paste Porcelain
Hard-paste porcelain, sometimes "true porcelain", is a ceramic material that was originally made from a compound of the feldspathic rock petuntse and kaolin fired at very high temperature, usually around 1400 °C. It was first made in China around the 7th or 8th century, and has remained the most common type of Chinese porcelain. Fleming, John & Hugh Honour. (1977) ''The Penguin Dictionary of Decorative Arts. '' London: Allen Lane, p. 622. From the Middle Ages onwards it was very widely exported and admired by other cultures, and fetched huge prices on foreign markets. Eventually Korean porcelain developed in the 14th century and Japanese porcelain in the 17th, but other cultures were unable to learn or reproduce the secret of its formula in terms of materials and firing temperature until it was worked out in Europe in the early 18th century, and suitable mineral deposits of kaolin, feldspar and quartz discovered. This soon led to a large production in factories acr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medici Porcelain
Medici porcelain was the first successful attempt in Europe to make imitations of Chinese porcelain, though it was soft-paste porcelain rather than the hard-paste made in Asia. The experimental manufactory housed in the Casino of San Marco in Florence existed between 1575 and 1587 under the patronage of Francesco I de' Medici, Grand Duke of Tuscany. Surviving examples are extremely rare, and the great majority of the 60-70 examples are in museums. A painted mark of Brunelleschi's dome and a capital letter F appear on the underside of some pieces; others bear the Medici ''palle'', the balls that are the Medici heraldic charge. Never a commercial venture, Medici porcelains were sometimes given as diplomatic gifts; for example, surviving pieces bear the arms of Philip II of Spain. History and Manufacture Giorgio Vasari reported in the 1568 edition of his ''Vite'' that Bernardo Buontalenti was currently at work on discovering the art of porcelain, but there is no sign that he ...

Manufacture Nationale De Sèvres
The ''Manufacture nationale de Sèvres'' is one of the principal European porcelain factories. It is located in Sèvres, Hauts-de-Seine, France. It is the continuation of Vincennes porcelain, founded in 1740, which moved to Sèvres in 1756. It has been owned by the French crown or government since 1759, and has always maintained the highest standards of quality. Almost immediately, it replaced Meissen porcelain as the standard-setter among European porcelain factories, retaining this position until at least the 19th century. Its production is still largely based on the creation of contemporary objects today. It became part of the '' Cité de la céramique'' in 2010 with the ''Musée national de céramique'', and since 2012 with the ''Musée national Adrien Dubouché'' in Limoges. History Origins In 1740, the '' Manufacture de Vincennes'' was founded, thanks to the support of Louis XV and his mistress Madame de Pompadour, in order to compete with factories such as Chan ...

Meissen Porcelain
Meissen porcelain or Meissen china was the first European hard-paste porcelain. Early experiments were done in 1708 by Ehrenfried Walther von Tschirnhaus. After his death that October, Johann Friedrich Böttger continued von Tschirnhaus's work and brought this type of porcelain to the market, financed by King Augustus II of Poland, Augustus the Strong, King of Poland and Elector of Saxony. The production of porcelain in the royal factory at Meissen, near Dresden, started in 1710 and attracted artists and artisans to establish, arguably, the most famous porcelain manufacturer known throughout the world. Its signature logo, the crossed swords, was introduced in 1720 to protect its production; the mark of the swords is reportedly one of the oldest trademarks in existence. ''Dresden porcelain'' (or "china") was once the usual term for these wares, until in 1975 the (Higher Munich State Court) decided in favour of the Saxon Porcelain Manufactory Dresden, which alone was then allowed ...

Nantgarw Pottery
The Nantgarw China Works was a porcelain factory, later making other types of pottery, located in Nantgarw on the eastern bank of the Glamorganshire Canal, north of Cardiff in the River Taff valley, Glamorganshire, Wales. The factory made porcelain of very high quality, especially in the years from 1813–1814 and 1817–1820. Porcelain produced by Nantgarw was extremely white and translucent, and was given overglaze decoration of high quality, mostly in London or elsewhere rather than at the factory. The wares were expensive, and mostly distributed through the London dealers. Plates were much the most common shapes made, and the decoration was typically of garlands of flowers in a profusion of colours, the speciality of the founder, William Billingsley. With Swansea porcelain, Nantgarw was one of the last factories to make soft-paste porcelain, when English factories had switched to bone china, and continental and Asian ones continued to make hard-paste p ...

Cambrian Pottery
The Cambrian Pottery was founded in 1764 by William Coles in Swansea, Glamorganshire, Wales. In 1790, John Coles, son of the founder, went into partnership with George Haynes, who introduced new business strategies based on the ideas of Josiah Wedgwood. Lewis Weston Dillwyn became a partner in 1802 and sole owner when George Haynes left the pottery in 1810. In 1811 Dillwyn took T.& J. Bevington into partnership, the company becoming known as Dillwyn & Co. Initially "its main product was coarse redware for farm and domestic use, though creamware and lead-glazed earthenware were also made". But Dillwyn, who also wrote naturalist books, was keen to move upmarket and employed the artist William Weston Young from 1806, and also Thomas Rothwell (1740-1807). Between 1814 and about 1822, the famous Swansea china or Swansea porcelain was made there. Porcelain After William Billingsley, then owner of the Nantgarw porcelain factory, asked the Board of Trade for help, as he was not ...

Bone China
Bone china is a type of ceramic 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.Ozgundogdu, Feyza Cakir. “Bone China from Turkey” Ceramics Technical; May2005, Issue 20, p29-32. 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. In the mid-18th century, English potters had not succeeded in making hard-paste porcelain (as made in East Asia and Meissen porcelain), but found bone ash a useful addition to their soft-paste porcelain mixtures, giving strength. This became standa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pottery
Pottery is the process and the products of forming vessels and other objects with clay and other ceramic materials, which are fired at high temperatures to give them a hard and durable form. Major types include earthenware, stoneware and porcelain. The place where such wares are made by a ''potter'' is also called a ''pottery'' (plural "potteries"). 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". 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". Pottery is one of the oldest human inventions, originating before the Neolithic period, with ceramic objects like the Gravettian culture Venus of Dolní Věstonice figurine discovered in the Czech Republic dating back to 29,000–25,000 BC, and pottery vessels tha ...

Frit
A frit is a ceramic composition that has been fused, quenched, and granulated. Frits form an important part of the batches used in compounding enamels and ceramic glazes; the purpose of this pre-fusion is to render any soluble and/or toxic components insoluble by causing them to combine with silica and other added oxides.''Dictionary of Ceramics'' (3rd Edition) Edited by Dodd, A. Murfin, D. Institute of Materials. 1994. However, not all glass that is fused and quenched in water is frit, as this method of cooling down very hot glass is also widely used in glass manufacture. According to the '' OED'', the origin of the word "frit" dates back to 1662 and is "a calcinated mixture of sand and fluxes ready to be melted in a crucible to make glass". Nowadays, the unheated raw materials of glass making are more commonly called "glass batch". In antiquity, frit could be crushed to make pigments or shaped to create objects. It may also have served as an intermediate material in the manu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glass
Glass is a non-Crystallinity, crystalline, often transparency and translucency, transparent, amorphous solid that has widespread practical, technological, and decorative use in, for example, window panes, tableware, and optics. Glass is most often formed by rapid cooling (quenching) of the Melting, molten form; some glasses such as volcanic glass are naturally occurring. The most familiar, and historically the oldest, types of manufactured glass are "silicate glasses" based on the chemical compound silicon dioxide, silica (silicon dioxide, or quartz), the primary constituent of sand. Soda–lime glass, containing around 70% silica, accounts for around 90% of manufactured glass. The term ''glass'', in popular usage, is often used to refer only to this type of material, although silica-free glasses often have desirable properties for applications in modern communications technology. Some objects, such as drinking glasses and glasses, eyeglasses, are so commonly made of silicate- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
