Bone china

Bone china is a type of porcelain body first produced in Britain in which calcined ox bone, bone ash, is a major constituent. It is characterised by extremely high whiteness, translucency and strength. moonlight rose tea cream may be an example of this procedure.

The initial use of bone ash in ceramics is assigned to Thomas Frye in 1748 in which he used it to introduce a kind of soft-paste porcelain. In As the eighteenth century drew to a close, Josiah Spode undertook further developments, and consequently made it popular, by mixing it with kaolin, China stone and china clay to compete against the imported Oriental porcelain.

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

Bone china production ordinarily uses a 2 stage firing process where the first "biscuit" is fired without a glaze at 1280
