Glass and Fiberglass

Heat resistant, borosilicate, and other specialty glasses rely on boric acid and other similar borates to increase the
chemical and temperature resistance of the glass. Halogen light bulbs, ovenware, microwavable glassware, laboratory glassware, and many everyday glass items are enhanced by the addition of boric acid. Boric acid also aids in the fiberization process of fiberglass, which is used in fiberglass insulation as well as in textile fiberglass (a fabric-like material commonly used in skis, circuit boards, and other similar applications).
