Copper

Copper is a metal that occurs naturally.  Its earliest use is dated to aroud 9000BC.  The beginnings of copper work required hammering copper ore, then applying heat.  Once copper could be melted, other elements were added creating alloys.  Copper can be hammered, or cast and is  reddish-orange to bluish-green in color.  Chemical testing is needed to distinguish between Copper alloys, pure copper, and bronze.
