This native copper was first used (c. 8000 bce) as a substitute for stone by Neolithic (New Stone Age) humans. Metallurgy dawned in Mesopotamia as copper was cast to shape in molds (c. 4000 bce), was reduced to metal from ores with fire and charcoal, and was intentionally alloyed with tin as bronze (c. 3500 bce).
