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. @t[~3300 BCE..1200 BCE]
- Composition: ~88% copper, ~12% tin (tin-bronze); earlier arsenical bronze used arsenic instead of tin @t[~3300 BCE..1200 BCE]
- Earliest tin-bronze: Mesopotamia and the Caucasus, ~3300 BCE @t[~3300 BCE]
- Spread to: Egypt, Indus Valley, China, Europe
## Development
- Copper smelting preceded bronze by ~2,000 years (Chalcolithic period)
- Copper smelting preceded bronze by ~2,000 years (Chalcolithic period)@t[~5300 BCE..3300 BCE]
- Arsenical bronze (copper + arsenic) preceded tin-bronze and was used widely in the early Bronze Age; tin-bronze eventually replaced it due to superior strength and non-toxic production [^3]
- Tin was scarce; long-distance trade networks developed to source it (Cornwall, Afghanistan, Southeast Asia) [^1]
- Lost-wax casting (cire perdue) technique enabled complex shapes; earliest known examples date to ~4500 BCE (Varna Necropolis, Bulgaria), with widespread bronze use from ~3500 BCE in Mesopotamia @t[~4500 BCE] [^4]
- Chinese bronze casting (Shang dynasty, ~1600 BCE) achieved exceptional sophistication, producing large ritual vessels via piece-mold casting rather than lost-wax@t[~1600 BCE..1046 BCE] [^2]
- Disruption of tin trade routes is considered a contributing factor to the Bronze Age Collapse (~1200 BCE), accelerating the transition to iron [^5]
## Impact
- Superior weapons: Swords, spearheads, armor
- Agricultural tools: Plows, sickles
- Monumental art: Statuary, ritual vessels
- Drove long-distance trade networks for tin and copper
- Superior weapons: Swords, spearheads, armor@t[~3300 BCE..1200 BCE]
