This is the same formula we've been using for 35 years for non-roasted sulfide ores. This is important - one must use four 8 penny nails with each assay in addition to this flux. Bend the nails in a U-shape in order for them to sit completely into the flux and drop them into the crucible. The iron will unite with the sulfur and other impurities and reduce the litharge to lead. Always check to see if some portion of the nails are still present when you finish the assay. If all the nails are gone, you didn't use enough nails so you must redo the assay using more nails. Use 3 times as much formula as ore. Silver-free.
