MB Formula 7.5 Oz Melting Flux
Melts brilliantly, brings down 100% of your gold, and repairs cracked metals.
MB Formula was invented over 60 years ago by a chemist whose brother, a jeweler, wanted to recover the most possible gold from his bench sweeps (filings). His problem was that the borax left in the slack after melting, was taking some of the gold with it. We’ ve all seen those tiny balls of borax with gold stuck to them. The tedious task of cracking each one with pliers to recover the gold is antiquated. Sadly, today the process for melting gold is exactly the same, so MB Formula was mass produced and marketed. MB Formula has successfully revolutionized the method!
