Frankford Arsenal 1 lb Tub of CleanCast Lead Flux for Case Casting for Reloading

I tried this flux for the first time recently and it works exceptionally well. I have been impressed with how much crap it pulls out of the lead compared to other fluxes. I recently recast some Oregon Trail silver alloy bullets that should have been pretty clean, considering the company's reputation. I boiled the lube off them, then washed with an industrial degreaser and plenty of scalding hot water so I know I didn't introduce anything. I still pulled about half the crap I would pull out of scrap lead with mediocre flux, very dirty by my standards. Other bullets I melted down from Speer (these were all old .45-70 bullets I don't use anymore) were even dirtier. I guess to save a buck, major manufacturers keep their lead kinda dirty. I like mine nice and clean because it makes prettier bullets. TIPS: Use about 1/8 tsp to 3-4lbs of lead. Add half, stir and let react for 15-30 seconds, let settle for 15-30 seconds then skim. Repeat. For really dirty lead, you might want to do it 3-4 times. Avoid dumping in a lot of flux at once because this is wasteful and ineffective. It's really up to you how clean you want it and keep in mind when you flux, you're removing a little bit of good lead every time you do it. If you get to the point where you are pulling off more lead than impurities, it's time to stop. IT IS VERY IMPORTANT TO WEAR A RESPIRATOR WITH 3M #60926 CARTRIDGES! I like to just spend a day making ingots from whatever lead I have to recycle (bullet core rejects from a bullet manufacturer at the moment) so I can focus on making great bullets another day. Aluminum cans with the tops cut off and the inside sprayed with Frankford Arsenal's bullet mold release make great ingot molds. It's really easy to just peel the aluminum off the ingot when done. I have and always will swear by Lee bullet molds (as well as their Factory Crimp Dies). With careful attention to detail, they cast bullets that can be used without sizing.

Cleans lead with minimal smoke. Quick acting. Good castings after cleaning.

This stuff works ready good. Awesome price too. Most times I can only get 1/2 lbs jars for $8 USD. Not too many places carry this casting flux at all so I bought a bunch of jars :)

Caused impurities to float up for skimming

I have used this for years as a final flux for my ingots once I put them in my bottom pour lead pots. I initially smelt and flux my scrap lead with candle wax before pouring into ingots. This Frankford flux still beings out an amazing amount of impurities once the ingot hits the pots again. One caveat is make sure you stir very well your alloy once you put the flux in not only to get the impurities to the surface but especially to make sure the tin and antimony are mixed back into the alloy. You can actually see it separate on top as a dull grey film. You want to keep as much of this as possible.
