[QUOTE="the cradler, post: 59772, member: 2523"] Listen to thedigger. This happened to me and a mate several years ago with a couple of grams of fine gold and flakes we sluiced at Nundle. I went to Chemical world and bought some nitric acid. I put the gold in about 30mls of the acid and in about 10 seconds the gold was returned to original lustre. Do it outside and stay upwind, hold your breathe if you want because it will not take long, dilute the acid with water before retrieving gold, and you will probably get more mercury from the fish you eat for dinner that night than the amount of mercury you are handling.
