Verdigris can be found in some piano actions forming especially in the center pin-bushing cloth area. Its effects can be purely cosmetic forming a greenish waxy substance, or more severe, with the action becoming sticky causing friction in moving parts. Piano technicians can remedy this problem (sometimes only temporarily) by cleaning with and alcohol mixture or by using a centerpin lubricant. In extreme cases it may be necessary to re-pin the part after replacing the bushing cloth. —Preceding unsigned comment added by Emmery (talkcontribs) 17:06, 2 April 2008 (UTC)

Verdigris Cu(CH3COO)2·[Cu(OH)2]3·2H2O ) > Copper(II) acetate is formed with acid whereas patina is a mixture of alcaline copper compounds. The two are often mixed up and use isn't consistent. Verdigris is toxic. (talk) 00:44, 8 December 2008 (UTC)


"... it was required by artists in Greece." what is meant by this? The etymology here does not seem well explained. — Preceding unsigned comment added by (talk) 18:53, 17 April 2012 (UTC)

German Version[edit]

Greetings! "Grünspan" is the german equivalent of Verdigris, but the german article is a disambiguation to Kupfer-(II)-Acetat, which is itself linked to Copper Acetate - I think it would make sense to have the german article linked to the Verdigris article. (talk) 16:58, 15 December 2015 (UTC)
