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 reuse fine silver castings, remove the oxides from the surface in a pickling solution and then tumble with burnishing compound to remove any remaining debris. We recommend a minimum 1:1 ratio of new grain to used silver.
Our fine silver is electrolytically produced in our state-of-the-art facility. The purity of the silver is a nominal 99.99%+ fine.
• 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.
