Having been a student of this thread, I have since been putting together the pieces of a conversation I had about a year or so ago with someone whom I cannot remember who, about the use of a substance called salammoniac. We were not discussing fluxing but as I recall it was centered around refining the dross that was skimmed off the pot over time and built up. I was going to make a few boat anchors with what I had accumulated but he said he would about once a year, melt his down and add about a teaspoon of this salammoniac and was able to convert the better part of his dross into useable lead for casting. I had always meant to purchase some but failed to do so. I was to get it from the company that I get my silicone mold material from, Contenti.
So having refreshed my memory of this conversation some, I went to their website and look the stuff up. I think it was $15.25 for a 25lb. pail. I am due to order some more mold material this week and may well get some of this and use it to flux with as stated on their website -

Anyone heard of this stuff? Stories to tell before I spend the money? Otherwise, I will keep you posted as I intend to give it a try. If nothing else, I have a ton of dross piled up that can now be recycled.
