Gentlemen and Ladies: I am aware of the use of Pb as a collector in a cupel; as well as the use of Ag and Au. I have used both of the these, with mixed results. Somewhere I read of using Bismuth. Anybody out there have any ideas? I leach primary with Chlorine/Acid/chlorox and seconday with Iodine/Acid. Good results. Looks great under the mike.
Appreciate any advice or practical knowledge. Oxy/acetelyne is my heat source. evo-au
