This is the most often used Assay Flux formula -contains lead for a collector. Just add this flux to any standard type ore and fire in any fire furnace. A 25 gram lead button will be produced with most standard ores. If the lead button is smaller than 20 grams one should redo the assay and add 5 grams of whole wheat flour (standard food flour). Use 3 times as much flux formula as ore. Guaranteed silver-free. International flux contains NO litharge - lead must be obtained locally. If you have a sulfide ore and do a roast at 1350°F on the sample, you can then use this flux with 2 nails to convert any remaining sulfides to oxide. This will typically give you a better recovery.
