# 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
