first melt

Melted down 12 salad forks today.  Yield was 465 grams of sterling silver nuggets...enough to make 32 half ounce coins.  I chop up the flatware and melt it like this to burn off any residual grime.  The nuggets soak in a warm acid "pickle" for a couple of hours to clean off the firescale.  Dry sodium hydrogen sulfate is mixed with water releasing a mild sulfuric acid.  Firescale is cupric oxide - stains left by the copper that is in sterling silver as it reacts with oxygen at high temperature.  79,85,51,0,W
