Firescoff® is a revolutionary heat activated ceramic spray coating. Firescoff® combines a fire scale preventer, a heat shield, a high performance non-fluorinated soldering flux (for both hard and soft solder) and the convenience of easy removal in warm water, all-in-one. Leading Jewelers and Jewelry Manufacturers have switched from using boric acid, paste soldering flux, and pickle solution to Firescoff® because Firescoff® is faster, offers more protection for gemstones, and features a no-acid, warm water cleanup. Firescoff is provided in a 1 oz. or 4 oz. spray bottle. Made in USA
"Additional tests of the fire scale-prevention aspect of the product proved it to be every bit as good as the literature claims. Pieces of sterling silver coated with Firescoff Flux showed no fire scale after being heated to near-fusion temperatures." — Art Jewelry Magazine
