This hand specimen consists of a chunk of amorphous raw copper. I do not call it "native copper", because even though it started out as such, it has been melted and then poured into a mold made out of wet straw. Thus, its form is not natural, nor is its green coating, which is made up of copper oxide mixed with a lacquer and other chemicals. The piece was completely covered with this coating and then partly ground to expose a few spots of fresh copper, which were then polished. Finally, it was completely coated with a clear lacquer to prevent further oxidation of the fresh copper surfaces.
