The Element of Copper
The chemical element of atomic number 29. A common reddish metallic element that is ductile and malleable and is one of the best conductors of heat and electricity.
Besides the beauty of natural copper and the various natural patina, it is also known for some of its health benefits. Copper has been recognized as being naturally antibacterial killing many germs and bacteria. Ionized copper was once used by ancient Egypt to purify water. Furthermore, positive and negative magnetic fields created by copper help energy flow through the body.
Patina is a thin layer that variously forms on the surface of copper, bronze, and similar metals; tarnish produced by oxidation or other chemical processes or any similar acquired change of a surface through age and exposure.
