Bone Ash

A secondary flux in glazes and occasionally used as an opacifier. The essential constituent used to produce translucency in bone china bodies. Typically made from ground, calcined animal bones, bone ash is a source of calcium phosphate.

This is a natural product. Our supplier states: "The material that we supply is a naturally occurring crystalline mineral powder, in the form of Hydroxyapatite (HYA), Ca10(PO4)6(OH)2, that is classified by UK and EU Customs as a ‘ground natural calcium phosphate'"
