The resistance of a canasite glass‐ceramic to the initiation of thermal stress fracture due to a water quench was found to be higher than for the original glass, due to higher values of strength and thermal conductivity which offset increases in thermal expansion and Young's modulus. Relative strength retention behavior of the glass‐ceramic was also higher than for the glass, attributed to its crack‐size‐dependent fracture toughness.
