Summary

Compositions surrounding the quartz-feldspar-mullite phase field eutectic were prepared with varying ratios of alkali feldspars to qualify the effects of alkali ratios on the eutectic composition and temperature. Small pyrometric cones and cylindrical pellets were fired to temperatures above the expected melting temperatures. Melting was not observed. The hindered reaction kinetics are proposed to be the result of a limited number of particle-particle contacts due to the large particle sizes of the raw materials used.
