Tin processing - Tin processing - Pewter: Another traditional use for tin that has been revolutionized by modern developments is pewter ware. The composition of this alloy has changed greatly, particularly with the elimination of the lead found in Roman and medieval alloys. Modern pewter ware is a high-tin alloy, containing from 90 to 97 percent tin and small additions of antimony and copper
