What is porcelain and how is it made?
Porcelain (/ˈpɔːrsəlɪn/) is a ceramic material made by heating materials, generally including a material like kaolin, in a kiln to temperatures between 1,200 and 1,400 °C (2,200 and 2,600 °F). Though definitions vary, porcelain can be divided into three main categories: hard-paste, soft-paste and bone china.
What makes porcelain china?
Porcelain was first made in China—in a primitive form during the Tang dynasty (618–907) and in the form best known in the West during the Yuan dynasty (1279–1368). This true, or hard-paste, porcelain was made from petuntse, or china stone (a feldspathic rock), ground to powder and mixed with kaolin (white china clay).
What is so special about porcelain?
They are hardness, whiteness and translucency. Porcelain has a high level of mechanical resistance, low porosity and high density, which, on a daily basis, provide it with durability, innocuity, soft touch and beauty.
What’s the best way to work with porcelain?
When sculpting with porcelain clay, remember that it is much harder to work with than other clays — porcelain clay should be used if you have already mastered the art of working with other forms of clay. Knead cold porcelain as you work to prevent any cracks or lines from appearing in the finished piece.
Which is the best definition of the term porcelain?
The term porcelain refers to a wide range of ceramic products that have been baked at high temperatures to achieve vitreous, or glassy, qualities such as translucence and low porosity. Among the most familiar porcelain goods are table and decorative china, chemical ware, dental crowns, and electrical insulators.
What are the raw materials used to make porcelain?
Raw Materials The primary components of porcelain are clays, feldspar or flint, and silica, all characterized by small particle size. To create different types of porcelain, craftspeople combine these raw materials in varying proportions until they obtain the desired green (unfired) and fired properties.
What was the role of porcelain in China?
In China the porcelain is simpler, in some ways less versatile than Western versions, but the Chinese artisans are building with it to make huge ware, sometimes metres high.

How did the English improve the recipe for porcelain?
Later in the eighteenth century the English further improved upon the recipe for porcelain when they invented bone china by adding ash from cattle bones to clay, feldspar, and quartz. Although bone china is fired at lower temperatures than true porcelain, the bone ash enables it to become translucent nonetheless.
