recommended procedure

SPRUNG: Use direct spruing with reservoir 6-8 gauge for single units, for bridges, use indirect spruing.

INVESTING: Use a high-heat phosphate bonded investment. Do not use investment that contains carbon. Do not use investment that contains carbon.

BURNOUT: Place a ring in cold burnout furnace and gradually bring up to 1500°F (816°C) After reaching burnout temperature, heat-soak rings for one hour.

CASTING: : Use Multi-orifice tip and oxygen (appr. 15 psi) with natural or propane gas. Preheat the crucible. Do not use crucibles that contain carbon. Place ingots in the crucible. Carefully heat the ingots in a slow circular motion. Maintain even heating. When the ingots being to slump, then cast the alloy. Do not overheat the metal.

FINISHING: After casting, bench cool to room temperature. Sandblast and finish using normal gold crown & bridge finishing technique.
