[QUOTE="LONEWOLF, post: 348061, member: 6309"] Hi Wishfull, I would say with-out touching and feeling, Manganese or if Really Heavy, a Silver/Lead/Zinc type of Ore.....try a good soak in water with some washing powder/detergent for a few days. Then use a scrubbing brush.... DO NOT use Oxalic acid... This will send Most metallic things Black. :( .. And very hard to 'Reverse', so to speak... Not too sure about 'other' acids as I don't use them.... Sometimes a week or two of soaking in water, removes a lot of stuff of the rock.... You could try a drop of Hydrochloric on it and see what reaction you get... or if you want the metallic look, chip away the crap and you will be left with a nice Specimen of 'Something'. ;) .. LW...
