Discovery of copper

8th millennium BCE

Copper was the first metal that people learned to work. Lumps of native copper, found pure in the ground, were hammered into beads, pins and small tools in the Near East, with some of the earliest worked pieces coming from sites in Anatolia such as Cayonu. Smelting copper from its ores, which allowed far greater production, developed several thousand years later, with early evidence in the Balkans and the Near East from around the fifth millennium BCE. The metal gave its name to the Copper Age, or Chalcolithic, that bridged the Stone Age and the Bronze Age. Once copper was alloyed with tin to make bronze, around the fourth millennium BCE, it became the basis of tools, weapons and trade across much of Eurasia, and it remains vital today for electrical wiring.
