To make up the batch of lithopone the solution containing the original 1050 pounds of barium sulphide and 856 pounds of titanium acid cake is added to sufiicient zinc sulphate solution of approximately 35 Baum at 60 Centigrade to completely precipitate all the BaS as zinc sulphide and barium sulphate so that the final precipitate contains a suspen-. sion of co-p'recipitated zinc sulphide barium sulphate intimately mixed with a suspension of titanium oxide. On the completion of the reaction, shown by the complete absence of either soluble zinc or barium in a filtered por-.

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 the pigment itself can vary in shade over time, ranging from pure white all the way to grey or even black. To suppress this effect, a dopant may be used, such as a 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.

  • When asked about the recent Skittles lawsuit, the FDA said the agency does not comment on pending litigation.

  • The brands of lithopone of the normal class, that of chemical manufacture, are marketed under such names as Ponolith, Beckton White, Jersey Lily White, Oleum White, Zinc Sulphide White, all of these being of domestic manufacture, and their composition is of the 30 per cent. zinc sulphide type. The German manufacturers and exporters of lithopone make use of fancy names for their brands and here are a few examples of these and the composition of the pigment:-
