Copper?

https://wiki.openstreetmap.org/w/index.php?title=Tag:material%3Dcopper&diff=prev&oldid=2948298 As person who has copper things at my house, I am sure about. (Copper oxide has specific appearance and colour) Something B (talk) 10:07, 27 January 2026 (UTC)

@Something B: It looks like, but it would be good to have an image where this can be confirmed by some reference. Even so, sometimes it is surprising what they find when checking material in the lab.

Maybe an image of unoxidated copper is the better default. --99 tabazan (talk) 10:19, 27 January 2026 (UTC)

You may find better image, in meantime I will restore previous one. Something B (talk) 11:01, 27 January 2026 (UTC)
