Get professional, repeatable results and a rich gold color with this 22-karat gold casting grain.

Special additives reduce firescale and promote good flow and fill, resulting in a smooth cast surface.

Formulated with deoxidants so you can mix 50% casting scrap with new casting grain and still get good results.

Sold by the pennyweight (dwt.), minimum purchase is 0.2 dwt.

Any casting method.

Casting and Cleaning
In general, your casting temperature should be 100˚F (37.7˚C) above the liquidus point (somewhat hotter if the castings are intricate). Use a small amount of high-quality flux when melting with an open flame. We recommend Matt’s Casting Flux™. For further cleaning, mechanical means are recommended.

If you plan to re-use gold castings, remove the copper oxides from the surface in a pickling solution or by mechanical means. We recommend a minimum 1:1 ratio of new grain to used gold. All re-used gold should be clean and free of debris.

• Due to the manufacturing process of casting grain, the grain will vary in shape and size. If you need perfectly round, consistently-sized spheres please see our granule products. • We strive to measure quantities ordered as closely as possible; however, due to manufacturing tolerances at the mill, please allow for a ±10% variance when ordering.
