The investment material compositions have the property of sufficiently decreasing in strength after cooling to facilitate the removal of the mold material by the removal solution. Two particular investment material compositions that possesses these properties are describe which contains powdered silica quartz, beta-hemi-hydrate calcium sulfate (gypsum), a hardening agent of potassium sulfate, and water. A mold removal solution composition is described that is composed of hydrogen peroxide solution in water.
