Chinese porcelain brush washer bowl

Porcelain material made by heating materials, generally including kaolin, in a kiln to temperatures between 1,200 and 1,400 °C (2,200 and 2,600 °F). The toughness, strength, and translucence of porcelain, relative to other types of pottery, arise mainly from verification and the formation of the mineral mullite within the body at these high temperatures.
