Copper: An Ancient Metal - Dartmouth Toxic Metals ...

Native copper was likely used first, as it did not require any process to purify it. It could have been hammered into shapes although it would have been very brittle. Annealing was the first step toward true metallurgy, when people discovered that copper became more flexible and easy to work with when it was heated before hammering.
