This investigation represents a first attempt to interpret the thermal behavior and constitution of bone china by means of a phase diagram of an idealized system. A consideration of the Tricalcium phosphate‐alumina‐sica phase diagram in relation to the quaternary system lime‐alumina‐phosphorus pentoxide‐silica indicates that the composition of a normally tired commercial bone china body is β‐tricalcium phosphate and anorthite in a siliceous glassy matrix. X‐ray examinations of many such bodies confirm this interpretation. This preliminary investigation indicates the most profitable fields for further research.
