Bone china is a type of porcelain body first developed in Britain in which calcined ox bone (bone ash) is a major constituent. It is characterised by high whiteness, translucency and strength. Production usually involves a two stage firing where the first, bisque, is without a glaze at 1280 °C (2336 °F), which gives a translucent product and then glaze, or glost, fired at a lower temperature below 1080 °C (1976 °F).

English manufacturers were keen to produce porcelain of the quality to be found in Chinese imports, but they had to go down a different route. The first use of bone ash in ceramics is attributed to Thomas Frye in 1748 to make a type of soft-paste porcelain, at his Bow China Works[2]. In the late 18th century, Josiah Spode undertook further developments, and subsequently popularised it, by mixing it with kaolin and China stone to compete with the imported Oriental porcelain.
