I have been using Carnauba Red Bullet Lube for flux in my pot. It is without question the most effective flux I have ever used. I mean it will take whatever slush is at the surface of the pot, which many call oxidized lead, and others call tin, and makes it go back into the melt. The slush pretty much 100% disappears. Nothing else that I have tried has done this. Now all I have tried was, first candles, second Midway flux, third saw dust and wood sticks. With all of the above, it never really did anything for the slush at the top.
Now my problem is that the Carauba Red stinks and smokes to high heaven when you burn it and I am sensitive to those things anyway, and it gets to me physically. When it is first applied it becomes an ugly slimy, oil that can actually climb the walls of the pot and is next to impossible to scoop off, and the thing to do is just apply it and leave it till it burns to an ash, when it is easily removed and no longer oily. In between, however, is a LOT of smoke.
So two questions. Have people found other things that work like the Carnauba that are less toxic, for want of a better word? Secondly, have I discovered a new miracle flux, or do others of you normally get your "oxidation", again, for want of a better word, to return to the melt so effectively?
