Abstract Scope Mullite forms in porcelain bodies because all porcelain bodies lie within the mullite phase field. The availability of Al2O3 dictates mullite formation and the amount of alumina available is controlled by the solubility of alumina in the glass phase. The glass formation boundary defines the alumina solubility limit. Through the analysis of 32 commercial and laboratory bodies, heat treated over a broad range of temperatures and soak times at peak temperature, mullite levels were measured using an internal standard method. The glass chemistry was obtained by subtracting the amount of mullite (and residual quartz) from the overall body composition. Analysis of the glass chemistries consistently generated alumina levels in the porcelain glass at 1.2 (0.1) moles of alumina per mole of flux. This level was independent of soak temperature and time. From these results the mullite levels in heat treated porcelains can be calculated from the overall body chemistry.
