This Sterilite™ De-Ox sterling silver casting grain delivers superior tarnish resistance—six times better than regular sterling silver—with a lower price point than Argentium® Silver. It provides excellent cast brightness and metal flow properties; the tight grain structure results in a smooth cast surface that reduces polishing time. This grain creates a bright white metal that stays bright for a long time without the need for rhodium plating. High fluidity during the casting process results in reduced porosity. Additionally, items cast with this grain have a Vickers hardness of 80 (heat-treating increases this hardness to 97).
