Porcelain is a ceramic material made by heating raw materials, generally including clay in the form of kaolin, in a kiln to temperatures between 1,200 °C (2,192 °F) and 1,400 °C (2,552 °F). The toughness, strength, and translucence of porcelain arise mainly from the formation of glass and the mineral mullite within the fired body at these high temperatures.
Porcelain derives its present name from old Italian porcellana (cowrie shell) because of its resemblance to the translucent surface of the shell. Porcelain can informally be referred to as "china" in some English-speaking countries, as China was the birthplace of porcelain making. Properties associated with porcelain include low permeability and elasticity; considerable strength, hardness, glassiness, brittleness, whiteness, translucence, and resonance; and a high resistance to chemical attack and thermal shock.
For the purposes of trade, the Combined Nomenclature of the European Communities defines porcelain as being "completely vitrified, hard, impermeable (even before glazing), white or artificially coloured, translucent (except when of considerable thickness) and resonant." However, the term porcelain lacks a universal definition and has "been applied in a very unsystematic fashion to substances of diverse kinds which have only certain surface-qualities in common" (Burton 1906).

Scope, materials and methods
The most common uses of porcelain are for utilitarian wares and artistic objects. It can be difficult to distinguish between stoneware and porcelain because this depends upon how the terms are defined. A useful working definition of porcelain might include a broad range of ceramic wares, including some that could be classified as a stoneware. Porcelain is used to make household wares, decorative items, and objects of fine art amongst other things.
Kaolin clay is the primary material from which porcelain is made, even though clay minerals might account for only a small proportion of the whole. The word "paste" is an old term for both the unfired and fired material. A more common terminology these days for the unfired material is "body", for example, when buying materials a potter might order an amount of porcelain body from a vendor.
The composition of porcelain is highly variable, but the clay mineral kaolinite is a significant component. Other materials can include feldspar, ball clay, glass, bone ash, steatite, quartz, petuntse and alabaster.
The clays used are often described as being long or short, depending on their plasticity. Long clays are cohesive (sticky) and have high plasticity; short clays are less cohesive and have lower plasticity. In soil mechanics, plasticity is determined by measuring the increase in content of water required to change a clay from a solid state bordering on the plastic, to a plastic state bordering on the liquid, though the term is also used less formally to describe the facility with which a clay may be worked. Clays used for porcelain are generally of lower plasticity and are shorter than many other pottery clays. They wet very quickly, meaning that small changes in the content of water can produce large changes in workability. Thus, the range of water content within which these clays can be worked is very narrow and the loss or gain of water during storage and throwing or forming must be carefully controlled to keep the clay from becoming too wet or too dry to manipulate.
The following section provides background information on the methods used to form, decorate, finish, glaze, and fire ceramic wares.
Glazing: Unlike their lower-fired counterparts, porcelain wares do not need glazing to render them impermeable to liquids and for the most part are glazed for decorative purposes and to make them resistant to dirt and staining. Great detail is given in the glaze article. Many types of glaze, such as the iron-containing glaze used on the celadon wares of Longquan, were designed specifically for their striking effects on porcelain.
Decoration: Porcelain wares may be decorated under the glaze using pigments that include cobalt and copper or over the glaze using coloured enamels. Like many earlier wares, modern porcelains are often bisque-fired at around 1,000 degrees Celsius, coated with glaze and then sent for a second glaze-firing at a temperature of about 1,300 degrees Celsius or greater. Another early method is once-fired where the glaze is applied to the unfired body and the two fired together in a single operation.
Firing: In this process, green (unfired) ceramic wares are heated to high temperatures in a kiln to permanently set their shapes. Porcelain is fired at a higher temperature than earthenware so that the body can vitrify and become non-porous.
Porcelain originated in China. Although proto-porcelain wares exist dating from the Shang Dynasty (1600–1046 BCE), by the Eastern Han Dynasty period (196–220) high firing glazed ceramic wares had developed into porcelain. Porcelain manufactured during the Tang Dynasty (618–906) was exported to the Islamic world, where it was highly prized. Early porcelain of this type includes the tri-color glazed porcelain, or sancai wares. The exact dividing line between proto-porcelain and porcelain wares is not a clear one to date. Porcelain items in the restrictive sense that we know them today could be found in the Tang Dynasty, and archaeological finds has pushed the dates back to as early as the Han Dynasty (206 BCE – 220 CE). By the Sui Dynasty (581–618) and Tang Dynasty (618–907), porcelain had become widely produced.
Eventually, porcelain and the expertise required to create it began to spread into other areas of East Asia. During the Song Dynasty (960–1279), artistry and production had reached new heights. The manufacture of porcelain became higly organized and the kiln sites, those excavated from this period, could fire as many as 25,000 wares. By the Ming Dynasty (1368–1644), porcelain art was being exported to Europe. Some of the most well-known Chinese porcelain art styles arrived in Europe during this era, such as the coveted blue-and-white wares. The Ming Dynasty controlled much of the porcelain trade, which were further expanded to all over Asia, Africa and Europe through the Silk Road. Later, Portuguese merchants began direct trade over the sea route with the Ming Dynasty in 1517 and were followed by Dutch merchants in 1598.
These exported Chinese porcelains were held in such great esteem in Europe that in the English language china became a commonly–used synonym for the Franco-Italian term porcelain. Apart from copying Chinese porclelain in faience (tin glazed earthenware), the soft-paste Medici porcelain in 16th-century Florence was the first real European attempt to reproduce it, with little success.
Early 16th century, the Portuguese brought back samples of kaolin clay, which they discovered in China to be essential in the production of porcelain wares, but the Chinese techniques and composition to manufacture porcelain was not yet fully understood. Countless of experiments to produce porcelain had unpredictable results and would meet with failure. In the German state of Saxony, the search concluded with an eventual discovery in 1708 by Ehrenfried Walther von Tschirnhaus that produced a hard, white, translucent type of porcelain specimen with a combination of ingredients, including kaolin clay and alabaster, mined from a Saxon mine in Colditz. It was closely guarded as a trade secret by the Saxon enterpise.
In 1712, many of the elaborate Chinese manufacturing secrets for porcelain were revealed throughout Europe by the French Jesuit father Francois Xavier d'Entrecolles and soon published in the Lettres édifiantes et curieuses de Chine par des missionnaires jésuites. The secrets of porcelain manufacturing, which d'Entrecolles read about and witnessed in China, were now known and began being used in Europe.
Von Tschirnhaus and Böttger were employed by Augustus the Strong and worked at Dresden and Meissen in the German state of Saxony. Tschirnhaus had a wide knowledge of European science and had been involved in the European quest to perfect porcelain manufacture when in 1705 Böttger was appointed to assist him in this task. Böttger had originally been trained as a pharmacist; after he turned to alchemical research, it was his claim that he knew the secret of transmuting dross into gold that attracted the attention of Augustus. Imprisoned by Augustus as an incentive to hasten his research, Böttger was obliged to work with other alchemists in the futile search for transmutation and was eventually assigned to assist Tschirnhaus. One of the first results of the collaboration between the two was the development of a red stoneware that resembled the red stoneware of Yixing.
A workshop note records that the first specimen of hard, white, and vitrified European porcelain was produced in 1708. At the time, the research was still being supervised by Tschirnhaus; however, he died in October of that year. It was left to Böttger to report to Augustus in March 1709 that he could make porcelain. For this reason, credit for the European discovery of porcelain is traditionally ascribed to him rather than Tschirnhaus.
The Meissen factory was established in 1710 after the development of a kiln and a glaze suitable for use with Böttger's porcelain, which required firing at temperatures up to 1,400 °C (2,552 °F) to achieve translucence. Meissen porcelain was once-fired, or green-fired. It was noted for its great resistance to thermal shock; a visitor to the factory in Böttger's time reported having seen a white-hot teapot being removed from the kiln and dropped into cold water without damage. Evidence to support this widely disbelieved story was given in the 1980s when the procedure was repeated in an experiment at the Massachusetts Institute of Technology.
Soft paste porcelain
The pastes produced by combining clay and powdered glass (frit) were called Frittenporzellan in Germany and frita in Spain. In France they were known as pâte tendre and in England as "soft-paste". They appear to have been given this name because they do not easily retain their shape in the wet state, or because they tend to slump in the kiln under high temperature, or because the body and the glaze can be easily scratched.
Experiments at Rouen produced the earliest soft-paste in France, but the first important French soft-paste porcelain was made at the Saint-Cloud factory before 1702. Soft-paste factories were established with the Chantilly manufactory in 1730 and at Mennecy in 1750. The Vincennes porcelain factory was established in 1740, moving to larger premises at Sèvres in 1756. Vincennes soft-paste was whiter and freer of imperfections than any of its French rivals, which put Vincennes/Sèvres porcelain in the leading position in France and throughout the whole of Europe in the second half of the 18th century.
The first soft-paste in England was demonstrated by Thomas Briand to the Royal Society in 1742 and is believed to have been based on the Saint-Cloud formula. In 1749, Thomas Frye took out a patent on a porcelain containing bone ash. This was the first bone china, subsequently perfected by Josiah Spode.
In the fifteen years after Briand's demonstration, half a dozen factories were founded in England to make soft-paste table-wares and figures:
- Chelsea (1743)
- Bow (1745)
- St James's (1748)
- Bristol porcelain (1748)
- Longton Hall (1750)
- Derby (1757)
- Lowestoft porcelain (1757)
William Cookworthy discovered deposits of kaolin clay in Cornwall, making a considerable contribution to the development of porcelain and other whiteware ceramics in the United Kingdom. Cookworthy's factory at Plymouth, established in 1768, used kaolin clay and china stone to make porcelain with a body composition similar to that of the Chinese porcelains of the early eighteenth century.
Categories of porcelain
Porcelain can be divided into the three main categories: hard-paste, soft-paste, and bone, depending on the composition of the paste, the material used to form the body of a porcelain object.
These porcelain that came from East Asia, especially China, were some of the finest quality porcelain wares. Hard-paste porcelain can sometimes be called "true porcelain", although this is an outdated term which is not recognised by any authority. The earliest European porcelains were produced at the Meissen factory in the early 18th century; they were formed from a paste composed of kaolin and alabaster and fired at temperatures up to 1,400 °C (2,552 °F) in a wood-fied kiln, producing a porcelain of great hardness, translucency, and strength. Later, the composition of the Meissen hard paste was changed and the alabaster was replaced by feldspar and quartz, allowing the pieces to be fired at lower temperatures. Kaolinite, feldspar and quartz (or other forms of silica) continue to provide the basic ingredients for most continental European hard-paste porcelains.
Soft-paste porcelains date back from the early attempts by European potters to replicate Chinese porcelain by using mixtures of clay and ground-up glass (frit) to produce soft-paste porcelain or, as these can be citation needed] called, "artificial porcelains". Soapstone and lime were known to have been included in these compositions. These wares were not yet actual porcelain wares as they were not hard and vitrified by firing kaolin clay at high temperatures. As these early formulations suffered from high pyroplastic deformation, or slumping in the kiln at raised temperature, they were uneconomic to produce and of low quality. Formulations were later developed based on kaolin clay with quartz, feldspars, nepheline syenite or other feldspathic rocks. These were technically superior and continue in production. Soft-paste porcelains are fired at lower temperatures than hard-paste porcelain, therefore these are in general less hard than hard-paste porcelains.[
Although originally developed in England since 1748 to compete with imported porcelain, bone china is now made worldwide. The English had read the letters, which describes in detail the Chinese porcelain manufacture secrets, given by Jesuit missionary Francois Xavier d'Entrecolles with avidity and it was said that a misunderstanding of the text was responsible for the first attempts to use bone-ash as an ingredient of English porcelain. In China, kaolin clay was sometimes described as forming the bones of the paste, while the flesh was provided by the refined rocks suitable for the porcelain body. For whatever reason, when it was first tried it was found that adding bone-ash to the paste produced a white, strong, translucent soft-paste porcelain. Traditionally English bone china was made from two parts of bone-ash, one part of kaolin clay and one part china stone (a feldspathic rock), although this has largely been replaced by feldspars from non-UK sources.
Electric insulating material
Porcelain is an excellent insulator for use at high voltage, especially in outdoor applications. Examples are: terminals for high voltage cables, bushings of power transformers, insulation of high frequency antennas and many other cases.
Porcelain can be used as a building material, usually in the form of tiles or large rectangular panels. Modern porcelain tiles are generally produced to a number of recognised international standards and definitions. Manufacturers are found across the world with Italy being the global leader, producing over 380 million square metres in 2006. Historic examples of rooms decorated entirely in porcelain tiles can be found in several European palaces including ones at Capodimonte, Naples, the Royal Palace of Madrid and the nearby Royal Palace of Aranjuez. and the Porcelain Tower of Nanjing in China. More recent noteworthy examples include The Dakin Building in Brisbane, California and the Gulf Building in Houston, Texas which, when constructed in 1929, had a 70-foot-long (21 m) porcelain logo on its exterior. A more detailed description of the history, manufacture and properties of porcelain tiles is given in the article “Porcelain Tile: The Revolution Is Only Beginning.”
