WebCoating Flux. After pickling the item, coat/dip it first in a boric acid flux that protects the entire piece from oxidation and fire scale (heavy oxidation that forms on the jewelry from copper in the metal). Fire scale is very difficult to remove. 60% boric acid and 40% denatured alcohol yields an excellent and inexpensive flux. Add the boric acid to the alcohol until it … WebFlux is a chemical cleaning agent containing an acid activator and sometimes a wetting agent to prepare surfaces for metal joining. These are blended or dissolved into a chemical carrier which can be a solvent, water or a thickening agent. Without flux the molten solder will not "wet" or flow into the surface of the parts being joined or coated.
