# Bronze Working # Bronze Working ## Overview Bronze working — the alloying of copper with tin — defined the Bronze Age (~3300–1200 BCE) and enabled advances in weaponry, tools, and art across Eurasia. ## Key Facts - Period: ~3300–1200 BCE (Bronze Age) - Composition: ~88% copper, ~12% tin - Earliest bronze: Mesopotamia and the Caucasus, ~3300 BCE - Spread to: Egypt, Indus Valley, China, Europe ## Development - Copper smelting preceded bronze by ~2,000 years (Chalcolithic period) - Tin was scarce; long-distance trade networks developed to source it (Cornwall, Afghanistan, Southeast Asia) [^1] - Lost-wax casting technique enabled complex shapes - Chinese bronze casting (Shang dynasty, ~1600 BCE) achieved exceptional sophistication [^2] ## Impact - Superior weapons: Swords, spearheads, armor - Agricultural tools: Plows, sickles - Monumental art: Statuary, ritual vessels - Drove long-distance trade networks for tin and copper --- [^1]: Muhly, J.D.
