Property: 
Boric acid, also called boracic acid or orthoboric acid or acidum boricum, is a weak acid often used as an antiseptic, insecticide, flame retardant and a precursor of other chemical compounds. White powder of scaled crystal, feeling greasy, odorless and tasteless, soluble in water, alcohol, glycerol ether and volatile oil, the water solution indicating weak acidity. when heating to 70-100ºC, hydro-extracting gently to change into meta-boric acid; 150-160ºC, as pyro-boric acid:300ºC, as boric anhydride(B2O3).

Uses:
ceramics, insecticides, heat-resistant glass (borosilicate glass), glass fibers, porcelain enamels, boron chemicals, welding fluxes, flame retardants, fungus control, eyewash solutions, and electroplating, Taxidermy (preserving).

For hardening steel. as a tooling life extender, as a mix in flux, fireproofing fabrics (if you stick or mig weld it will stop those annoying little holes) and weatherproofing wood; as a preservative; manufacture of cements, crockery, porcelain, enamels, glass, borates, leather, carpets, hats, soaps, artificial gems; in nickeling baths; cosmetics; printing and dyeing, painting; photography; for impregnating wicks; electric condensers.

In the health area it is used as an eyewash, an astringent, as an antifungal where it gets rid of yeast infections and an antiviral, against cold sores.

Pest Control, it is one of the safest! It works by dehydrating the little bastards. No heavy toxins. It works against ants, silverfish, termites, roaches, earwigs and fleas, among others. You still have to keep it away from little children though , and specially babies...if they should eat it, it could kill them by the dehydration and system
