  Technology - Wikipedia, the free encyclopedia
The advantages of copper tools over stone, bone, and wooden tools were quickly apparent to early humans, and native copper was probably used from near the beginning of Neolithic times (about 8000 BCE).
Native copper does not naturally occur in large amounts, but copper ores are quite common and some of them produce metal easily when burned in wood or charcoal fires.
Eventually, the working of metals led to the discovery of alloys such as bronze and brass (about 4000 BCE).
