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.

Caused impurities to float up for skimming

This flux really cleans up your lead when casting bullets. A must have to get impurities out.

I am new to the whole lead casting scene. My husband and I have just started our own business making fishing lures and we decided to start making our own lead fishing weights as another service that we offer. This is the first lead fluxing powder that we have used and we have been highly impressed with this lead flux powders performance. It does improve the consistency of the melted lead and it is non-smoking, and odor free just like the description says. We will definitely be repeat customers!

Works great for fluxing lead.

When I began bullet casting years ago, about all we had to flux a melt with was beeswax or alox. This did a poor job of cleaning the melt, and contributed to dross accumulations in the pot. These new white metal fluxes produce a cleaner melt and better bullets. They don't burn, and smoke production during fluxing is minimized. Vitrified dross is easy to skim off the melt. Recommended.

You don't need much of this to flux your casting lead. Works pretty well, a lot better than throwing in a too big piece of candle wax! Recommended.

I've been using Brownell's version of Frankford Arsenal flux for more than 20 years and it has been excellent for those of us who must cast indoors. Contrary to what others say, it does not rust or otherwise "crud up" casting pots or bullet moulds. However, it is hygroscopic, meaning it readily absorbs water, so if you live in a humid climate, keep the jar tightly covered (and put it in a sealed plastic bag for good measure!).

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 :)

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.

I have always used bullet lube or wax to flux lead alloys but the smoke is a pain and the idea of having a low smoke alternative appealed a lot. This product work well and it produces minimal smoke. However it is highly hydroscopic. I use a lead ladle to mix the lead and there was some of the residual material still on it when I set it aside. I came back 2 days later to do some more casting and I did not inspect the ladle before putting it into the molten lead. There was an explosion and with my PPE, there was not a problem but I have never had something like that happen before. Residual bullet lube will cause smoke but no explosive type reaction. So I would rate the material as very effective but be aware of the potential risk of water when using it. After using it more I would urge extreme caution due to it hydroscopic nature and the risk of lead splatter
