Bone china

Bone china is a kind of porcelain body originally used in Britain in which calcined ox bone, bone ash, is an important ingredient. It is characterised by extreme whiteness, translucency and strength. dinnerware set may be an example of this process.

The initial use of bone ash in ceramics is credited to Thomas Frye in in the late 1740s in which he used it to introduce a type of soft-paste porcelain. In At the close of the 18th century, Josiah Spode undertook further developments, and subsequently popularised it, by combining it with china clay, China stone and kaolin to compete against the imported Oriental porcelain.

The original elementary recipe of three and a half parts china clay, four parts china stone, and six parts bone ash remains the standard English body.
