Mixed Shot Steel Media
Used to burnish jewelry to give is a shiny finish. Since it does not have any abrasives in it, there is no metal removed, and cast pieces must be prepared with abrasive media first to remove scratches and sharp edges before they are burnished. Carbon steel media is more economical, but requires maintenance. It must be used with a rust inhibitor and stored in special compounds. Stainless steel media will not rust and requires little care.
