text: The following example is illustrative of the invention: 300 pounds of commercial-grade boric acid is dissolved in gallons of hot water; the solution is heated to about 93 C., and the specific gravity adjusted to about 1.04 by adding the requisite amount of commercial-grade boric acid; the solution is then filtered, and concentrated sulfuric acid is added to the filtrate until the pH thereof is 3.0 to 4.0; the solution is cooled to about 30 C. or lower, whereupon the boric acid separates in crystalline form; the crystals are separated from the mother liquor by centrifugation, and washed with cold distilled water.
