recommended procedure
WAXING: 6-10 gauge sprues, direct casting for single units and indirect method for multiple units.
INVESTING: : Any carbon free high heat Investment is recommended. Use not-asbestos ring finer. Bench set 1 1/2 hours. Place in cold furnace and gradually bring u p to 1650° F. Hold for 1 1/2 hours.
CASTING: High Heat quartz crucibles are recomŽmended, along with a multi-orifice torch, using a gas/oxygen mixture or in an electric Induction casting machine. When the ingots completely slump the alloy is then ready to be cast After the casting, bench cool to room temperature.
FINISHING: Grind the metal with non-contaminated aluminum oxide stones. After grinding, blast with non-recycles 50 micron aluminum oxide, and dean let distilled' Water i n ultrasonic cleaner for tea minutes.
OPAQUE: No degassing or conditioner necessary. Apply opaque wash and bake. Then full opaque coat and bake.
