Bone china

Bone china is a kind of porcelain body originally developed in the United Kingdom in which calcined ox bone, bone ash, is an important ingredient. It is differentiated by high whiteness, translucency and strength. moonlight rose open sugar 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 type of soft-paste porcelain. In As the 18th century drew to a close, Josiah Spode carried on with further developments, and consequently popularized it, by mixing it with kaolin, china clay and China stone to compete with the imported Oriental porcelain.

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

The manufacture of bone china routinely makes use of a 2 stage firing process where the first "biscuit" is fired without a glaze at 1280
