Lithopone is produced by the simultaneous precipitation of zinc sulfate and barium sulfide. Lithopone was an important white pigment for painting purposes until the large-scale production of titanium white. The opacity of Lithopone is good, although slightly lower than that of Titanium White. Lithopone is not suitable for acidic materials.
