A highly concentrated source of boric oxide for glazes. Anhydrous borax is made by burning or fusing hydrated borax. It thus contains little or no water of crystallization (conversation ratio of .53 compared to hydrated decahydrate borax) and does not rehydrate under normal storage conditions. Anhydrous borax is water soluble, but considerably less so than raw borax (in aqueous solution it can provide slow release of boron).
Borax (sodium tetraborate hexahydrate or sodium borate) is a naturally-occurring mineral composed of sodium, boron, oxygen and water. It has been used as a remedy for over 4000 years.Most commercially-produced borax is mined from deposits produced by the repeated evaporation of seasonal lakes.n some countries such as Australia, New Zealand and the USA, you can buy borax in the laundry and cleaning section of your supermarket.
