Pharmacologia. New York: W. E. Dean. The rust of the spear of Telephus, mentioned in Homer as a cure for the wounds which that weapon inflicted, was probably Verdegris, and led to the discovery of its use as a surgical application While blue copper is not found in nature, aged and antique copper can occur naturally with cycles of damp and dry to create the browns. With this technique, it’s not so bad if the surface is a bit rough, because the paint will cover it, and the patina process always adds a lot of texture anyway. a b Solomon, Sally D.; Rutkowsky, Susan A.; Mahon, Megan L.; Halpern, Erica M.

I didn’t show a few more recipes that they discuss above, like one with boiled eggs and a couple with ammonia.

One other verdigris copper salt is the light green anarakite (CuZn 2) 2(OH) 3Cl) named after the Anarak province in Iran.
