Do you know what bronze is? It is an alloy or mixture of tin and copper, which is harder and more durable than pure copper or tin.

The Bronze Age primarily took place between 3500 B.C., and 1,200 B.C., and is traditionally divided into the Early Bronze Age, Middle Bronze Age and Late Bronze Age. It began in the present-day areas of Turkey, Iran, and Iraq, which was also the cradle of human civilization.
