Pewter is a metal alloy, traditionally between 85 and 99 percent tin, with the remainder commonly consisting of copper, antimony and lead. Copper and antimony act as hardeners while lead is common in the lower grades of pewter

Pewter is cast like most metals, but at a lower temperature.

Modern pewters must contain at least 90% tin to be considered a pewter. They also no longer contain appreciable amounts of lead, which has been replaced by copper, antimony and bismuth
