This copper specimen was likely given its form and coloration in a laboratory environment. It shows no evidence of crystal form or crystalline tendencies, and is very flat on one side of it, making me think that molten copper was dropped into a shallow basin of cooling solution. Furthermore, it appears to be coated with an oxidizing solution that gave the copper the bright green color that is normally associated with its oxidized state. A small amount opposite the flat surface of the piece has been ground away to expose fresh metal- it has the classic coppery-red coloration and metallic luster of the metal. The entire piece is coated with a thin layer of clear lacquer to prevent loss of the oxide coating and further oxidation .
