The physical mechanisms that determine the retained strength of ceramics after thermal shock are studied by measuring experimentally and statistically the density and depth of cracks produced in the interior of the ceramics. The analysis indicates that the key factor controlling the retained strength is the maximum depth of cracks rather than the density of cracks in the ceramics. The result presented here forms a basis to further understand the thermal shock behavior of ceramic
