Bone china

Bone china is a type of porcelain body first developed in the United Kingdom in which calcined ox bone, bone ash, is a major part. It is distinguish by extremely high whiteness, translucency and strength. boch dinnerware villeroy may be an example of this process.

The initial use of bone ash in ceramics is attributed to Thomas Frye in seventeen-forty-eight in which he used it to develop a kind of soft-paste porcelain. In As the eighteenth century drew to a close, Josiah Spode continued with further developments, and subsequently popularised it, by combining it with china clay, China stone and kaolin to compete with the imported Oriental porcelain.

The initial elemental formula of three and a half parts china clay, four parts china stone, and six parts bone ash is still the standard English body.

The manufacture of bone china consistently involves a two stage firing process where the first "biscuit" is fired without a glaze at 1280
