Borax Technical Grade in a 1 Pound Bag, this is Borax Pentahydrate in the Granular form. Borax has a wide variety of uses, a component of many products. It can be used to glaze ceramic crucibles, as a flux in casting and soldering.
Borax when used in melting of Gold and Silver helps to dissolve Oxides and other impurities and produce a fluid borate slag that collects on the surface of the molten metal. This slag is periodically removed, by use of a carbon-graphite or clay rod.
