The Statue of Liberty, showing advanced patination; verdigris is responsible for the statue's iconic green colour.. Verdigris (/ ˈ v ɜːr d ɪ ɡ r iː (s)/) [1] is a common name for any of a variety of somewhat toxic [2] [3] [4] copper salts of acetic acid, which range in colour from green to a bluish-green depending on their chemical composition.
Patina is also found on slip rings and commutators. This type of patina is formed by corrosion, what elements the air might hold, residue from the wear of the carbon brush, and moisture; thus, the patina needs special conditions to work as intended. Patinas can also be found in woks or other metal baking dishes.

According to the disambiguation page, verdigris is a type of patina. — Tajik24 03:37, 20 July 2007 (UTC) I think I am right in saying that verdigris is the green patina found on copper alloys. Other patina colours such as red, blue or black can also be achieved on copper alloys, and on other metals.
