I cannot explain it any better than this this does,
The Simple Act Of Fluxing
I have used both sawdust and paraffin as flux along with the lube from bullets that managed to make it all the way to the lube before getting culled.
What I have found that works for me is to flux with sawdust in my bigger smelting pot twice, and then just before I am ready to pour my ingots I will flux once more with paraffin more or less to get any remaining crumbs or whatever out of the alloy before I began to pour ingots.
When I load my Lee 4-20, I only use paraffin in this stage as I usually don't have the alloy in there for very long. I also try my best to pour my bullets at the lowest temp I can to try and avoid the tin oxidizing out as well. I reflux the pot after I add more ingots, and usually after dumping in a can of cut sprues. This give me a good clean pot and clean alloy when I pour.
