Chola Bronze Metallurgy
Chola Empire · 850 – 1250 CE Thanjavur
Ask AI about thisThe Cholas perfected the lost-wax (cire-perdue) casting of bronze icons, achieving alloy control and surface detail that remain unmatched, exemplified by the Nataraja.
Chola bronzes were cast in a precise copper-tin-lead alloy (often near the pancha-loha tradition) using single-pour lost-wax moulds. Metallurgical analysis of surviving icons reveals deliberate alloy tuning for both castability and the warm patina prized in temple worship — an applied materials science centuries ahead of its time.
