The Effects of Oxidation on Copper Sciencing

Copper's element symbol --- Cu --- is derived from the Latin "cuprum," which translates to "metal of Cyprus," indicating where it was mined in ancient times. In fact, copper has been used by humans for about 10,000 years. Today, copper appears in products from cookware, electrical wires and plumbing to jewelry and sculpture. Under certain conditions, these copper items can be affected by ...

Copper(I) oxide - Wikipedia

Cuprous oxide is commonly used as a pigment, a fungicide, and an antifouling agent for marine paints. Rectifier diodes based on this material have been used industrially as early as 1924, long before silicon became the standard. Copper(I) oxide is also responsible for the pink color in a positive Benedict's test.
