  • Refreshes old gold during the melting process

I finally tried it! Followed the tip given to me

I finally tried it! Followed the tip given to me by an old jeweler friend. Melted half my filings using my regular way, and the other half using MB Formula. The MB yielded higher gold collection. Wish i had done it sooner.
