Silver is a remarkable medium for artistic expression. It takes well to engraving, sculpting, casting, and fine detail while also having sufficient strength (especially in alloys) to insure the durability of art objects formed from this metal. Unfortunately, silver tarnishes when exposed to moist air, and removing layers of tarnish can damage the fine detail of artistic treasures. A new method for preventing the ravages of silver tarnish is now being developed by researchers in Maryland.
