This specification covers the barium sulfate pigments commercially known as barytes and blanc fixe. The pigment shall consist of barium sulfate (BaSO4) without any admixture of other materials in the case of blanc fixe, and without any admixture of other materials not naturally occurring in the barite ore in the case of barytes. The pigments shall be subjected to the following tests: coarse particle test, moisture test, barium sulfate test, ferric oxide test, free silica test, hydrogen ion concentration, and matter water solubility test.
