Exactly. American jewelry junkies see that oxidation and say 'greenies', but it's not a term I'd expect a Dutch speaker to know.

 

Well, I know it from your use of it over the years, but that doesn't mean I will start using it. We all have our specific expressions and terms, sometimes generally accepted terms, other times idiosyncracies.
I don't think anyone else on the forum has ever used "the greenies", American or otherwise. So maybe a very local thing, in your area?

On the more important question: Why you tried to correct me by saying the same thing I did. That is still a mystery, but I am fine with leaving it one of the forum's mysteries.

 

It's in use among resellers and collectors; I learned it from people who live a thousand miles (1500KM+) away, so not local to me. I only posted it because the pin also had chipped green paint on some leaves with the oxidation on their edges. I wasn't sure if the two had been confused or not.

 

A colloquial terms are OK in a limited setting, but an official term (technical/physics) is generally accepted and recognized worldwide. It was that way when I grew up with my metallurgist father, and it was that way when I started my bricks and mortar shop in 1982. When reading literature or speaking to other collectors or sellers it is still that way.

So the use of the term verdigris is clear to everyone, whereas a term like "the greenies" is vague and open to interpretation. In fact, when you google "the greenies", it is not suggested as an alternative for verdigris/copper oxidation.
Some examples that do appear have nothing to do with metal whatsoever:

So please don't "correct" me when I use an official and generally accepted term that is absolutely correct in that particular instance. Manners aside, it could lead people to think the correct term is incorrect.

 

Like my pet peeve, "rainbow moonstone"....yeeeargh! It would be fine if there was no real stone called moonstone, but every time I see someone thinking they bought moonstones it's enough to make me want to yell "Labradorite!" I have no problem calling copper oxide copper oxide; I was raised by a metallurgist too.
