[QUOTE="22shells, post: 145122, member: 3817"] Before I give it a soak and a tap, just for fun I thought I'd try and get an idea of how much gold is in it. Using the formula (wet weight x 3.1)-(dry weight x 1.9) = gold weight. Came up with 3.36 grams. A different method gave 4.17 grams. Obviously there are a few variables such as the specific gravity of quartz and if there are any impurities in it, so it's only an estimate. [/QUOTE]
