Real World Context
Porcelain is a ceramic material made by heating materials, generally including a material like kaolinite (Al2Si2O5(OH)4), in a kiln to temperatures between 1,200 and 1,400 °C (2,200 and 2,600 °F). The strength, and translucence of porcelain, relative to other types of pottery, arises mainly from vitrification and the 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.
Its manufacturing process is more demanding than that for earthenware and stoneware, the two other main types of pottery, and it has usually been regarded as the most prestigious type of pottery for its delicacy, strength, and its white color. It combines well with both glazes and paint, and can be modeled very well, allowing a huge range of decorative treatments in tablewares, vessels and figurines.
Porcelain is also referred to as china or fine china in some English-speaking countries, as it was first seen in imports from China. Properties associated with porcelain include low permeability and elasticity; considerable strength, hardness, whiteness, translucency and resonance; and a high resistance to chemical attack and thermal shock. Porcelain has been described as being "completely vitrified [i.e. turned to glass], hard, impermeable (even before glazing), white or artificially colored, translucent (except when of considerable thickness), and resonant".
