Germanium-based Sterling Silver Casting Grain Announced

United Precious Metal Refining has introduced its latest Germanium-based sterling silver casting grain, Sterlium. It is a patented formulation specifically created for the demands of the silver industry for premium tarnish resistance and a snow-white colour. This casting grain provides excellent metal fluidity, greater surface hardness for luster and high metal re-usability. It also helps secure gemstones firmly in place and enhances its brightness due to contrast. It is recommended to be used in automated or enclosed casting machines.
