Goldstar XXX

It is an ideal investment powder for casting Silver, all Yellow Gold, and can withstand the demands of White Gold alloy up to 18k and can be used for casting both by the centrifugal or vacuum assisted methods.

Gold Star XXX is a robust investment yet still produces excellent quality castings with superb surface finish and fineness of detail. When mixed, XXX wets up readily, producing a slurry which has greater flow characteristics and allows for the finest of detail of the wax pattern to be faithfully reproduced; XXX also cleans off the mould very easily.

Gold Star Powders are the only investment manufacturer in the world to produce their own highest grade unmineralised cristobalite and silica at our calcining and milling facility. This economy of scale allows us to produce top quality investment powders at competitive prices without compromising quality.
