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 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.
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.
• 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.

•IMPORTANT: Sterling silver is an alloy containing metals that react with chemicals found in air and produce tarnish; high moisture levels, exposure to sunlight and contaminants such as salt water increase this reaction. Take steps to protect your sterling silver by keeping it in airtight packages, use tarnish-resistant products (such as tarnish tabs or strips) that absorb harmful chemicals, and store metals in a cool, dry place. Most tarnish is easily removed by polishing with a mild abrasive or soaking in an anti-tarnish solution.
