Fine Pewter is basically Tin and a small amount of Antomony. Most
all Pewter sold in the US these days is “fine” (containing NO lead).
Much of the pewter being imported into the US as small sculpture
forms and jewelry often does contain lead. Other uses for pewter are
buttons, service ware (plates and the like), all sorts of decorative
items (lamps, bowls, candle sticks, drawer pulls, belt buckles, etc).
There are many alloy formulas for pewter, each developed for specific
casting needs and use needs.
