F_2_06 — Tin Sources and the Bronze Age Mystery

The Bronze Age (c. 3300–1200 BCE) depended fundamentally on tin — the scarce metal alloyed with copper to produce bronze (typically 88–92% copper, 8–12% tin). While copper was widely available across the Mediterranean, N

F_3_04 — Spread of Metallurgy: Copper, Bronze, Iron Across the Ancient World

Metallurgy developed independently in multiple regions, beginning with native copper use by ~9000 BCE and smelting by ~7000 BCE in Anatolia. The transition from copper to arsenical bronze and then tin bronze reshaped anc
