    • n baryta Barium oxid, BaO: also called heavy earth, because it is the heaviest of the earths, its specific gravity being 4.7. It is a gray powder having a sharp, caustic, alkaline taste, and a strong affinity for water, with which it combines to form barium hydrate. It forms salts with the acids, all of which are poisonous, except the sulphate, which is quite insoluble in the juices of the stomach. The carbonate of baryta is much used in the preparation of beet-root sugar, and in the manufacture of plate-glass and of colors. Formerly called baria.
