In this video I show the process of refining sterling silver using nitric acid to dissolve the sterling. Then, I use the lye and sugar method to precipitate out at least 99.67% pure silver. I also use XRF testing to demonstrate the purity difference between refined silver using the lye and sugar method and a US minted walking liberty coin.
