The benefits of copper tools over stone, bone, and wooden instruments have been rapidly apparent to early humans, and native copper was most likely used from near the beginning of Neolithic times . Native copper doesn't naturally happen in giant amounts, however copper ores are fairly frequent and a few of them produce metallic simply when burned in wooden or charcoal fires. Eventually, the working of metals led to the discovery of alloys similar to bronze and brass . The first uses of iron alloys corresponding to metal dates to round 1800 BCE.
