Here is my latest video on the process I use to RECOVER gold from gold filled watch cases and gold filled jewelry, then I REFINE the recovered gold to
a high purity.
Having some familiarity with the classical processes as documented by Georgius Agricola in "De Re Metallica" (and later authors), I look forward to viewing your procedures...

that was very well done, I'm glad you went to all that trouble to make it, as I found that quite interesting
