Question

which is the most main invention of copper age

Answer 1

Answer:

chalcolithic

Explanation:

In the Chalcolithic period, copper predominated in metalworking technology. Hence it was the period before it was discovered that adding tin to copper formed bronze (a harder and stronger metal). The archaeological site of Belovode, on Rudnik mountain in Serbia, has the oldest securely-dated evidence of copper smelting, from 7000 BP (c. 5000 BC).[3][4]

The Copper Age in the Ancient Near East began in the late 5th millennium BC and lasted for about a millennium before it gave rise to the Early Bronze Age. The transition from the European Copper Age to Bronze Age Europe occurs about the same time, between the late 5th and the late 3rd millennia BC
