Recovering the gold plating from these rings and jewelry a customer sent over for me to experiment with. These rings should have some gold plating on them and we are using some assaying and metallurgy techniques to determine the amount of gold that we can recover. We use the cupel method for determining the weight of gold in 3 rings and also melt down several rings and use an XRF gun to determine the percentages of metals in the entire alloy.
