Copper is an essential mineral found in plant life and in the human body and it is also a metal alloy with a reddish-orange color. The use of copper dates back over 10,000 years. Pure copper is very soft and malleable and is combined with other metals, such as brass and bronze, for use in jewelry and other uses. Copper is used in currency (the U.S. penny), and is used as a heat conductor, in medical instruments, and has been used as a decorative coating of famous gates, such as the Temple of Jerusalem, sculptures, and statues, most notably, The Statue of Liberty, the largest copper statue in the world.
Since 100% of copper can be recycled without any loss of its original mined quality, it is the third most recycled metal. Over 80% of the copper mined since it was discovered thousands of years ago is still in use today. When copper tarnishes, a beautiful green patina covers the piece.
