The melting point of gold is 1063 c, which is a higher temperature than can be obtained by cheap torches and burners.By adding borax to the heavy mineral concentrate, the melting point temperature decreases, allowing people to melt gold out of their concentrate and salvage.By using borax, no mercury flour is produced, and gold recovery.
Nothing fancy here, just lots of grunting and groaning.Often the use of a knife, scraper or pick in the hands of a skilled technician is the most controlled technique for removing solder mask from areas where you dont want it.No special setup is needed but operator fatigue can be a drawback on large projects.
