Where anhydrous boric acid is not available, the recipe must be modified to 43% sodium nitrate, 39% silica and 18% boric acid. The major innovations with respect to conventional wisdom is the avoidance of soda ash, fluorspar and pyrolusite, and the use of fused borax (anhydrous boric acid B203, also known as borax glass) rather than borax ...
