Get professional, repeatable results with our best-selling, .925 sterling silver shot casting grain. We start with the best raw materials, so that you get a smooth cast. Our manufacturing team has honed special processes to keep our silver casting grain oxygen- and gas-free. You enjoy consistent quality and composition over time, with a bright-white, lustrous finished metal. Applications 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. Re-Using If you plan to re-use sterling silver 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 silver. All re-used silver should be clean and free of debris. Composition The copper used in alloying our sterling silver is 99.9% pure and oxygen-free. Each batch of casting grain is assayed to ensure product that contains 92.5% silver. All ingredients are kept in an oxygen-reduced atmosphere during the melting and pouring process to ensure optimum deoxidation.
