Thermal endurance in the field zircon‐calcium zirconium silicate‐clay was evaluated together with those physical properties that should contribute most to this characteristic. The coefficient of thermal expansion was similar throughout the field, resulting in an area of high thermal endurance which coincided quite closely with that of high transverse strength. The best compositions did not fail until the 500 °F. quenching cycle (one cycle at each temperature) and withstood 30 cycles from 400°F. Petrographic analysis revealed that good thermal endurance could be attained over a wide range of compositions.
