Sterilite™ De-Ox Sterling Silver Casting Grain
Save polishing time and get superior tarnish resistance with Sterilite™ De-Ox sterling silver casting grain. The tight grain structure delivers a smooth cast surface, reducing polishing time. The resulting bright white metal resists tarnish six times better than regular sterling silver. Your casts will stay bright for a long time, without the need for rhodium plating. Cast items have a Vickers hardness of 80 (heat-treating increases this hardness to 97). 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.
