MB Formula Melting Flux

Description

Using borax as a flux when melting gold often results in some gold content in your borax residue. Using MB Formula instead will yield the most gold from filings and bench sweeps while providing a brilliant melt. And it eliminates the time-consuming mess of removing hidden gold from borax residue. MB Formula is a powder, and is provided in a jar containing 7.5 ozs. of flux.
