Abstract
In making light-proof lithopone, the zinc salt solution, the baryta lye, and the water used in the process, are purified and clarified by producing small quantities of a purifying medium in the liquids. For example, a small quantity of an iron or aluminium salt is added, and precipitation is effected by adding a slight excess of a carbonate, phosphate or hydrate, the liquids being then boiled and filtered. The barium sulphide solution is obtained by treatment of a baryta lye, purified as described above, with sulphuretted hydrogen.
