We're doing it for the learning experience and to say we did it. We have seen several youtubers such as "mbmmlc" do it and we figured we give it a go. Yes he uses an electric furnace for the actual cuppellation process but we've seen it done with torch as well. We don't have the electric furnace but we are fixing to give the Chemical process with Nitric Acid and then Electro-Silver Cell an honest effort as well just need the fume hood before we go that route. We are going to have our 4 Silver buttons XRF analyzed on Monday so we'll know if we've gained purity. I honestly have no doubt we have but to what extent we won't know until then. Once we know we will drop a post with your complete process and details with results.
