Pewter is a malleable metal alloy, traditionally 85–99% tin, with the remainder consisting of copper, antimony, bismuth and lead. Copper and antimony act as hardeners while lead is common in the lower grades of pewter, which have a bluish tint. It has a low melting point, around 170–230 °C (338–446°F), depending on the exact mixture of metals. The word pewter is probably a variation of the word spelter, a colloquial name for zinc.
