Playing a significant role in history for at least 10,000 years, copper is reddish in color and has a high electrical and thermal conductivity. Copper has many household uses including wires, doorknobs and other fixtures, plumbing, roofing, and cookware products. Most American coins are largely comprised of this element , while the Statue of Liberty contains 179,200 pounds of copper. It is also used to make several musical instruments, especially brass instruments and cymbals. Copper is essential to all higher plants and animals and is transported mainly in the bloodstream.
