Should a grade of lithopone be desired higher than the standard grade and another by-productas, for example, a forty-five*per= cent. grade of lithopone and barium chlorid the following process may be pi'acticed,\vhich, however, is quite analogous to the one already 10o described. Aqueous solutions of the ingredients are prepared as before, in these proportions: zinc sulfate, one hundred and sixty-one pounds; zinc chlorid, one hundred and thirty-six pounds, and barium sulfid, three hundred and thirty-eight pounds. Upon mixing these several solutions the lithopone will at once be precipitated in accordance with the following reaction:
