A mixture of borax and ammonium chloride is used as a
flux when welding iron and steel It lowers the melting
point of the unwanted iron oxide, allowing it to run
off. Borax is also used mixed with water as a flux when
soldering jewelry metals such as gold or sliver . It
allows the molten solder to flow evenly over the joint
in question. Borax is also a good flux for "pre-
tinning" tungsten with zinc – making the tungsten soft-
solderable. Borax is often used as a flux for forge
welding
