Using Borax Flux to Refine G Manhattan G amp; Silver

Aug 07, 20130183;32;This is because using borax as the flux reduces the melting point of all the elements in a piece of ore, including g. While out in the field, a g prospector can grind and wash a piece of ore, then mix it with borax in a plastic bag. The bag is then placed in a bowl or crucible and heated. The heating action is what triggers the borax to go to work. Once the borax melts, it lowers the melting temperatures of everything in the ore.
