Low quality pewter is tin, lead and a small amount of copper. In higher quality pewter, antimony or bismuth is used instead of lead. Pewter alloyed with antimony and bismuth can be polished to a bright, tarnish free finish. The alloying metals lower the melting temperature of tin, making it possible to cast molten alloy into detailed shapes.
