Boric acid in gypsum slurry promotes the formation of large bulky crystals as opposed to long needle-like ones. The bulky gypsum crystals impart a more rigid character to the board and in the presence of the effect of boric acid is to increase paper bond, through interaction with the starch. This prevents the formation of brittle edges.
