Bone Ash - crude


Glaze opacifier

Bone Ash-crude, is a common name given to dibasic dicalcium phospate dihydrate( CaHPO-H2O ). This material is derived from a ground ash.

  • The average chemical composition is 25%-Cacium with a phosphorus content of 18.5% at minimum.
  • Florine is an inherent impuity in natural bone ash, but it is contained to a maximum concentration of .05%. This product is grainy in nature with a mean particle size of 100 mesh & finer. Up to 22% can be  of 80 mesh particles.
  • Synthetic bone ashes are processed to a much finer particle size. However synthetically derived bone ashes used in the industry have a primary chemical composition of tricalcium phosphate which often render higher melting temperatures and do not always work in low temperature glaze applications.
