replies: text: 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.Plantsurfer (talk) 17:37, 2 April 2008 (UTC)

message: 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 (talk • contribs) 17:06, 2 April 2008 (UTC)

message: Greetings! "Grünspan" is the german equivalent of Verdigris, but the german article https://de.wikipedia.org/wiki/Gr%C3%BCnspan is a disambiguation to Kupfer-(II)-Acetat https://de.wikipedia.org/wiki/Kupfer%28II%29-acetat, which is itself linked to Copper Acetate https://en.wikipedia.org/wiki/Copper%28II%29_acetate - I think it would make sense to have the german article linked to the Verdigris article. 143.50.241.35 (talk) 16:58, 15 December 2015 (UTC)

message: Assuming that the Statue of Liberty is mentioned here, we should use American English. However, I see uses of British English in the article. Which English do we use? PeterPrettyCool (talk) 18:46, 2 March 2021 (UTC)
replies: text: The guideline that applies here is , (along with  as this is a chemistry related article). Typically, whichever variant is predominantly used in the article is the one used throughout and going forward. Sometimes people will go with whichever variant was used first when the article was created. This article should be designated as British English, for both those reasons.There are some exceptions, such as "strong national ties to a topic" , but I don't believe that applies here, just because there is an image of the Statue of Liberty (imho).Hope this helps. - wolf 05:49, 1 May 2022 (UTC)
