Although barium sulfate is almost completely inert, zinc sulfide degrades upon exposure to UV light, leading to darkening of the pigment. The severity of this UV reaction is dependent on a combination of two factors; how much zinc sulfide makes up the pigments formulation, and its total accumulated UV exposure. Depending on these factors Lithopone B301, Lithopone B311 powder itself may vary in shade over time, ranging from pure white all the way to grey or even black. To suppress this effect, a dopant might be used, like small amount of cobalt salts, which would be added to the formulation. This process creates cobalt-doped zinc sulfide. The cobalt salts help to stabilize zinc sulfide so it will not have as severe a reaction to UV exposure.

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.
