PostForum: What is it? - Where is it from?   Posted: Jul 23, 2021 07:27   Subject: Re: Black, metallic, yellow oxide?
My first guess was a pseudomorph of ferberite or hubnerite after scheelite from Trumbull, CT. Ron Januzzi had a big collection of these at his old rock shop near Brewster, NY, back in the 1980s.

Have you cleaned it at all yet? I would say start with soap and water and a plastic scrub brush. I would not use a copper cleaner on it, since that will remove the naturally weathered patina.

The bonsai are magnificent. Did the labels give the information of how many years old they are? I know some of them can successfully grow for decades.

Iron Out will remove a lot of the iron oxide stains, or you could use muriatic acid. If part of the matrix is marble/calcite, then the acid will attack it, resulting (maybe) in several smaller specim ...
