WAXING: 10 gauge sprues, direct casting for single units and indirect method for multiple units.

INVESTING: : Any carbon free high heat investment is recommended. Use non?asbestos ring liner. Bench set 1 1/2 Hrs. Place in cold furnace and gradually bring up to 1650°F Hold for 1 1/2 hrs.

CASTING: High heat quartz crucibles are recommended along with a multi?orifice torch, using a gas/oxygen mixture or in an electric induction casting machine. When the ingots completely slump and begin to coalesce, the alloy is then ready to be cast. After casting, bench cool to room temperature and then quench.

PREPARATION: After case is fitted, sandblast with aluminous oxide compound 50-60 microns. Put in ultrasonic unit with distilled water for 10 minutes. Remove and dry.

OPAQUE: De-gas at 1750°F under vacuum for 10 minutes. Bench cool, apply a thin wash of opaque, then full opaque. Follow your normal porcelain technique. Compatible with major porcelains, including Vita.
