in metal refining, a flux is sort of like a cleaning agent because it helps remove impurities from a sample. with some borax, heat, and a little know-how, it’s possible to extract pure gold from a sample of ore. this is because using borax as the flux reduces the melting point of all the elements in a piece of ore, including gold.
