	There were items tried that would still leave oil residue in the alloy and a real bitch to burn off before perfect bullets could then return to being the norm. So I just no longer flux same as Jack Hughes has pointed out and I only get the dirty trash on the top. JLous

	I take it that some of you don't burn off the lube because you cast indoors somewhere. I cast out of doors and flux with paraffin or lube leavings. I ignite it if it doesn't touch off by itself. I cast pretty hot compared to most. I do believe that that removes the residue, leaving only a small amount of ash. If I do it twice there is so little ash that it's hard to remove without taking metal out beyond my wishes when I skim. So, only flux once, if ya know what I mean. Plenty of ways to flux.

	Many ways to skin a cat and what ever works out best for each is indeed the best way. JLouis

	When I am alloying up a 75 pound batch I use sawdust for fluxing and do it a couple of times. I use a cast iron kettle, a turkey fryer flame source of heat for the bottom of the pot and a weed burner flame on the scrap lead in the cast iron kettle. When I first start up the Lyman 20 pound pot I skim off any sludge looking stuff if there is any present in the melt. Then I put a sort of aluminum cap on the lead in the pot and drop the sprues onto the aluminum as I cast. No fluxing when I cast bullets.

	Corn meal stirred carefully into the mix. I discovered this when I ran out of kitty litter to coat the top surface and the only thing in the kitchen was corn meal. The cornmeal carbonized. When I lifted the mess off the top, there was dross stuck to it. I experimented with corn meal as a flux and it cleans to shiny alloy. There are some definite steps since corn meal is hygroscopic. 1. Light sprinkle on top and let it simmer to assure any water (moisture) is gone, then stir. 2. The corn meal will smoke and start to turn brown, that is the time to stir. 3. Stir 4. This will smoke, I light the mixture to get rid of the smoke. 5. Skim the residue off the top and dispose. The Marvelux I have was free. I only use Marvelux when processing 100 pound batches of wheel-weights or scrap lead. It sticks to the side of the pot and will only come off with vigorous scraping.

	I am another one that gave up using a flux. I scrap off the trash as soon as the pot melts since the impurities melt at a higher temperature and you can scoop it off just after your alloy melts at a much lower temperature.

Are you had dipping or bottom pouring?
