WebBecause copper slowly reacts with oxygen, water and carbon dioxide from atmosphere. Firstly, it forms copper (I) oxide (Cu2O, which is brick red), but for a long time it reacts also with HCO3- ion and formed Cu (OH)2CO3 which is green. It is called patina. Besides, many copper salts are colored (most often different shade of blue and green). Artists and metalworkers often deliberately add patinas as a part of the original design and decoration of art and furniture, or to simulate antiquity in newly made objects. The process is often called distressing. A wide range of chemicals, both household and commercial, can give a variety of patinas. They are often used by artists as surface embellishments either fo…
