Description

This Prestige Optima investment delivers an ultra smooth casting surface and captures even the most delicate details. It works great with RP resins and 3D models. The investment is forgiving and user friendly; break out is good. This premium quality investment forms a strong, permeable mold that enables full-fill castings on gold, silver, brass and other non-ferrous metals that melt at less than 2,000°F (1,093°C) when casting using centrifugal or vacuum casting methods.
