On the basis of this study the following conclusions may be made: (1) A strong linear relationship exists between the thermal shock resistance and compatibility index values of the systems studied. (2) Compatibility index analysis and thermal shock testing are promising approaches for evaluation of porcelain-metal compatibility. (3) Further refinements of the model are necessary to account for the effects of stress relaxation, thermal diffusivity, thermal history, elastic modulus, porcelain tensile strength, and geometry on the predicted stress state of porcelain-metal systems.
