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!
Q: Do I mix MB Formula with borax?
A: No. It is not necessary to use borax or anything else with it. MB Formula replaces borax.
Q: I don’t melt my bench sweeps; I just send it to the refiner.
A: With gold valued over $1200 per ounce, it is advantageous to have a better understanding of how much you are giving to the refiner. A melted ingot will give you a much better idea of the collected value than a jar of gold dust. Therefore, melting your bench sweeps before giving it to the refiner will help you to better estimate the outcome.
Q: Is MB Formula a refining process?
A: No. MB Formula is not a refining process. It facilitates the melting process. Whatever metals you work with that fall into your bench sweeps, is what your ingot will contain.
Q: How does MB Formula repair gold that cracks while I’m rolling it out?
A: While MB Formula was made for the purpose of facilitating melting, it was discovered that it can also repair gold that cracked while rolling wire or plate. The reason why gold may crack while rolling it is because the gold contains impurities, such as lead or iron. These impurities do not fuse with the gold, so it causes a separation which creates the crack. When the gold is re-melted with the same amount as its weight of MB Formula, the MB Formula cleans up these impurities by attaching them to it and taking them up to the slack that is left on top of the melted gold. The cleaned gold is weighed down to the bottom of the ingot mold
