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 is used frequently in homemade laundry soap, dishwashing powders, and personal care products. The question often arises: Is borax safe to use? Borax, also known as sodium borate, sodium tetraborate, or disodium tetraborate, is a naturally occurring mineral composed of sodium, boron, oxygen, and water.(The scientific name for borax is sodium tetraborate decahydrate.) It is a white powder consisting of soft, colorless crystals that dissolve quickly in water.orax, also known as sodium borate, sodium tetraborate, or disodium tetraborate, is a naturally occurring mineral composed of sodium, boron, oxygen, and water.
