Bone china is a type of porcelain body first developed in Britainin which calcined cattle bone (bone ash) is a major component. It is characterised by high whiteness, translucency and strength. Production usually involves a two stage firing where the first, bisque, is without a glaze at1280 °C(2336 °F), which gives a translucent product and then glaze, or glost, fired at a lower temperature below1080 °C(1976 °F).
