 Bronze

 Bronze is a metal alloy or embroidery made of tin and copper. Metalworking began Copper began in 8000 BC.  It originated in the Middle East in 1800 BC.  It also comes from rocks and minerals. Then, five hundred years later, man mixed copper and tin to make bronze.  The casting was easy.  Once solidified, it hardens harder than copper. This method arrived in Europe much later.  The Iron Age is actually the Bronze Age before 1500 BC. It is the metal that man made on a large scale.  It has also been discovered that copper can be obtained from ground rocks through heat and evaporation.  However, the importance of bronze has never been and never will be denied.
