history of copper
Copper has been an essential material to man since prehistoric times. In fact, one of the major 'ages' or stages of human history is named after a copper alloy: bronze. Copper was the first metal used by man in any quantity. The earliest workers in copper soon found that it could be easily hammered into sheets and the sheets in turn worked into shapes which became more complex as their skill increased.
It was the copper metals which were used when a combination of strength and durability was required. The ability to resist corrosion ensured that copper, bronze and brass remained as both functional and decorative materials during the Middle Ages and the successive centuries through the Industrial Revolution and on to the present day.
Copper is man's oldest metal, dating back more than 10,000 years. A copper pendant discovered in what is now in northern Iraq. The Egyptians used the ankh symbol to denote copper in their system of hieroglyphs. It also represented eternal life. Copper axes were manufactured by casting in the Balkans in the 4th millennium BC. The ancient Romans extracted copper ores on Cyprus.
