The solution of orthoboric acid and borax in 4:5 ratio is used as a fire retarding agent of wood by impregnation. [38] It is also used in the manufacturing of ramming mass, a fine silica-containing powder used for producing induction furnace linings and ceramics. Boric acid is added to borax for use as welding flux by blacksmiths. [39]
Fire-retardant materials should not be confused with fire-resistant materials. A fire resistant material is one which is designed to resist burning and withstand heat. An example of a fire-resistant material is one which is used in bunker gear worn by firefighters to protect them from the flames of a burning building.
The fireproofing of wood utilizes a fire retardant chemical that remains stable in high temperature environments. The fire retardant is applied under pressure at a wood treating plant like the preservatives described above, or applied as a surface coating. In both cases, treatment provides a physical barrier to flame spread.

Borax is also mixed with water as a flux when soldering jewelry metals such as gold or silver, where it allows the molten solder to wet the metal and flow evenly into the joint. [ citation needed ] Borax is also a good flux for "pre-tinning" tungsten with zinc , making the tungsten soft-solderable. [ 31 ]
