Abstract
Compression and distortion on a wax pattern during curing are eliminated by employing a thermochromatic dye which changes color when investment material sets. By monitoring the dye, the set investment material can be removed from the assembly before curing, eliminating compression forces on the wax pattern from the exothermic curing process expanding the investment material against the constraints of the assembly.
