Anhydrous Borax is a white crystalline powder that does not contain any water molecules and does not readily absorb moisture under normal atmospheric conditions. Its an excellent flux for Gold and noble metal casting. Anhydrous borax is an excellent glass former since its boron content is so high.This material is used as a source of B2O3 in the manufacture of many different types of borosilicate glass, including heat and chemical resistant glasses, illumination glasses, optical lenses, medical and cosmetic containers, hollow microspheres and glass beads. It has a higher bulk density and melts more rapidly than raw forms of borax.
