Borax glass (Na2B4O7) is frequently used with gold alloys because of its affinity for copper oxides. An often-cited soldering flux formula'-' is borax glass (55 parts), boric acid (35 parts), and silica (10 parts). These ingredients are fused together and then ground into a powder. Fluxes are available in powder, liquid, or paste form.
