When was bronze discovered?

The discovery of bronze is marked as a step forward in human progress. Tools and weapons made out of bronze have been discovered in the Egyptian pyramids of 2500 BC. But it has been proved that this metal was in use at least a thousand years earlier. Bronze is an alloy made of two or more metals being fused together. For many centuries, the early man had been using copper in its pure form. It is believed that it was by accident that copper and tin probably got fused together accidentally and man discovered the better and harder alloy called bronze. The first bronze objects were cast in open moulds. The shapes of the objects were chipped in flat stones, and the heated metal was poured into it and left to cool.
