3. Application 
The primary industrial use of boric acid is in the manufacture of monofilament fiberglass usually referred to as "textile fiberglass". Textile fiberglass is used to reinforce plastics in applications that range from boats, to industrial piping to computer circuit boards. Boric acid is used in nuclear power plants to slowdown the rate at which fission is occurring. Fission chain reactions are generally driven by the amount of neutrons present (as products from previous fissions).

Boric acid is used in producing the glass faceplates of LCD flat panel displays. In electroplating, boric acid is used as part of some proprietary formulas. It is also used in the manufacturing of "remming mass", a fine silica-containing powder used for producing induction furnace linings. Borates including boric acid have been used since the time of the Greeks for cleaning, preserving food, and other activities. It is used in pyrotechnics to prevent the amide-forming reaction between aluminum and nitrates. A small amount of boric acid is added to the composition to neutralize alkaline amides that can react with the aluminum. Boric acid dissolved in methan is popularly used among fire jugglers and fire spinners to create a deep green flame. Boric acid is added to salt in the curing of cattle hides, calfskins and sheepskins. Used in that way it helps to control bacteria development and also aids in the control of insects.

Boric acid is used in the manufacture of glass (borosilicate glass), glazes and enamels, leather, paper, adhesives, and explosives. It is widely used (particularly in the USA) in detergents, and because of the ability of fused boric acid to dissolve other metal oxides it is used as a flux in brazing and welding. Because of its mild antiseptic properties it is used in the pharmaceutical industry and as a food preservative.

Boric acid is an effective preservative against yeast. It is used in concentrations of 0.01 to 1.0 percent and has fair to good antiseptic properties. It may also be used as a buffer and denaturant. Boric acid is prepared from sulfuric acid and natural borax. It can cause skin rashes and irritation if used in high concentrations. The use of boric acid in cosmetic preparations is no longer very popular.
