Bone china

Bone china is a kind of porcelain body originally used in the UK in which calcined ox bone, bone ash, is an essential ingredient. It is characterised by brilliant whiteness, translucency and strength. 222 dinnerware fifth may be an example of this process.

The first use of bone ash in ceramics is assigned 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 eighteenth century, Josiah Spode undertook further developments, and duly made it popular, by mixing it with China stone, kaolin and china clay to compete against the imported Oriental porcelain.

The initial elemental recipe 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 commonly involves a two stage firing process where the initial "biscuit" is fired without a glaze at 1280
