Comment

Pewter is a malleable metal alloy composed of 85–99% tin, mixed with approximately 5–10% antimony (in earlier times lead), 2% copper, bismuth, and sometimes silver. Copper and antimony act as hardeners but may be replaced with lead in lower grades of pewter, imparting a bluish tint. Pewter 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 term for zinc alloys (originally a colloquial name for zinc).
