 ## 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. @t[3300 BCE..1200 BCE]
+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]
 
 ## Key Facts
-- Period: ~3300–1200 BCE (Bronze Age) @t[3300 BCE..1200 BCE]
+- Period: ~3300–1200 BCE (Bronze Age) @t[~3300 BCE..1200 BCE]
-- Composition: ~88% copper, ~12% tin
+- Composition: ~88% copper, ~12% tin (tin-bronze); earlier arsenical bronze used arsenic instead of tin @t[~3300 BCE..1200 BCE]
-- Earliest bronze: Mesopotamia and the Caucasus, ~3300 BCE @t[~3300 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 technique enabled complex shapes
+- 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 @t[~1600 BCE] [^2]
+- 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
+- Superior weapons: Swords, spearheads, armor @t[~3300 BCE..1200 BCE]
-- Agricultural tools: Plows, sickles
+- Agricultural tools: Plows, sickles @t[~3300 BCE..1200 BCE]
-- Monumental art: Statuary, ritual vessels
+- Monumental art: Statuary, ritual vessels @t[~3300 BCE..1200 BCE]
-- Drove long-distance trade networks for tin and copper
+- Drove long-distance trade networks for tin and copper @t[~3300 BCE..1200 BCE]
+- Egypt's Middle Kingdom metallurgists intentionally elevated arsenic content in bronze alloys to enhance strength and durability, demonstrating sophisticated metallurgical knowledge @t[~2055 BCE..1650 BCE] [^6]
