Pewter

Malleable tin alloy with copper and antimony.

Pewter tableware has been cast since antiquity; Roman and medieval households ate from pewter plates and tankards for centuries.
Modern pewter is typically 91-98% tin hardened with antimony and copper, having abandoned the lead of historical formulations.
Its low melting point near 230 °C allows casting in silicone or plaster molds, keeping it popular for figurines, tankards, and jewelry.
