I bought a lb of Frankford Arsenal flux to try it. I have always used sawdust and beeswax when melting into ingots then beeswax only in Lee pots. I put a small amount of the Frankford in one of my Lee pots and it did some bubbling and there was a small bit of crap came to the top. I’m sure if I would have used beeswax the same would have happened.
I did notice that the pot and stirring spoon have a weird coating to them now. Is this normal? I keep my pots clean and every few pot fills I empty them, take out valve assembly, use a wire brush on a drill and clean them out as I’m always using different alloys.
I have some wheel weights and other dirty lead that I’m going to smelt into ingots and will try the Frankford in the cast iron pot I use for smelting.
I’ve read so many posts about how bad the Frankford or Marvelflux are and then some that it’s the second coming. I just don’t want to make a mess of the Lee pots if it’s not going to work any better than what I’m using.
I don’t want to hear about all other kinds of flux just how is the Frankford flux working.
