[TheForge] Welding flux?

[Jerry Frost]

Have you tried forge welding with them? Have any around, wanna give it a 
shot?

The commercial forge welding fluxes work much better than what I mix up 
but they're pretty darned expensive not counting shipping. My standard 
home brew is 1pt boric acid to 3pts. borax and I like it better than 
straight borax. I'd sure like an alternative that works better I can 
afford. Ah, another of life's quandries.

The can says it's for brazing, bronzing, etc. cast iron, steel, SS; torch welding, brass, bronze, etc. It's a dry powder flux and the claim is it melts low temp, works on greasy, rusty and dirty, it cleans, deoxidizes and floats scale off and is no more toxic than hot borax. The usual, don't get it in your eyes, breath it or eat it, may be a skin irritant. It's boric acid, borax and iron.
