Copper Age (1 jan 6000 ano antes da era comum – 1 jan 1200 ano antes da era comum)

Descrição:

chemists in this age were only interested in materials that had a value to humans. this included metals like gold because it didn't tarnish from its attractive colour, and was soft enough to be made into wire. copper was also majorly used as well during this time because it could be used to make pots, tools, jewellery, coins and was strong enough to produce weapons.
