[QUOTE="Rex, post: 307521, member: 9399"] I would be surprised if it does not prove to be Malachite (Copper,Cu) Test: Scrape off a bit of the green, crush it into a powder and add it to a teaspoon filled with vinegar and a sprinkle of salt. Put the bowl of the spoon over a flame & boil it dry. If it is copper there should be a copper coating on the spoon. You have also ruined a spoon, but now you know if it is copper or not :-) Avoid the fumes while you boil it, because no matter what it is, it might contain arsenic. [/QUOTE]
