(1) The existence of a linear relationship between the peak area in the differential thermograph, A, and the heat of reaction, ΔH, was discussed, and it was deduced that the ratio, A/ΔH, should change little with temperature. (2) This deduction was confirmed by the measurement of the heat of inversion for several salts, and it was noted that the correction term due to the difference in heat capacity could be large. (3) The differential thermograph for titania-opacified enamel was explained quantitatively by this theory. The heat of precipitation of titanium oxide in the frit was estimated to be about 11 kal/M, and also it was numerically confired that the broad peak found between 550° and 800°C was due to an apparent endothermic reaction accompanying the change in packing of the specimen.
