ABSTRACT OF THE DISCLOSURE A bone ash for the manufacture of bone china comprises calcined bone on which has been incorporated by calcination a source of B2O3. The incorporation of the B2O3 in the bone ash facilitates the manufacture of bone china, particularly promoting the formation of the micro- crystalline phase which is characteristic of bone china, thereby making it possible for bone china to be made with a wider firing temperature range, in a shorter time and if desired, lower temperatures than normal.
