Quite obviously mixtures of grades different from the above may be prepared by adding varying quantities of the ingredients named or of certain other ingredients in addition, such as kaolin, and then subjecting the whole to a mixing process, the higher grades of the lithopone containing the higher percentages of zinc sulfid. This has up to the present time been the actual method pursued in making commercial lithopone of different grades, although one not eminently satisfactory.
The reaction liquid is filtered through plate and frame pressure to obtain lithopone in the form of a filter cake with a moisture content of no more than 45%. It is then roasted in a drying furnace to change the crystal form of lithopone, and is then pickled with sulfuric acid at a temperature of 80°C. Finally, it is washed with water, reinforced with colorants, filtered, dried and ground into powder.
