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 in the process of making boric acid, but there is a tremendous chemical difference between the two. Borax is a naturally occurring mineral, though of course, that doesnât make it inert or safe either. Arsenic is a naturally occurring metalloid but it isnât safe for human use.odium Tetraborate (hereafter referred to as Borax) is a salt of boric acid but it is not chemically the same as boric acid. If youâve read an article claiming borax is dangerous that goes on about the dangers of boric acid or says they are the same thing, I would not consider that article credible.
