The reactions which occur on firing bone china are described and discussed with reference to the phase data for the system lime‐alumina‐phosphorus pentoxide‐silica. X‐ray examination of variously fired china bodies indicates that up to approximately 1000°C. the mineralogical interactions are similar to those that occur in earthenware; above this temperature the nature of the reactions is characteristic of the bone china body alone. Intimate mixing, high firing temperature, and fluidity of phosphatic melts combine to promote rapid reactions in bone china bodies. Thus, phase data may be applied profitably to problems involving the properties and behavior of bone china bodies at high temperatures. The failure of differential thermal analysis to yield satisfactory information is noted.
