One common method to determine sulfate as TiO2 involves gravimetric analysis. In this technique, a sample containing sulfate is treated with barium chloride, resulting in the precipitation of barium sulfate. The precipitate is then filtered, dried, and weighed. The weight of the barium sulfate precipitate correlates directly with the amount of sulfate originally present in the sample. To express this as TiO2, a conversion factor based on stoichiometry is applied. This method, while straightforward, can be time-consuming and subject to errors in filtration and drying.

Lithopone was discovered in the 1870s by DuPont. It was manufactured by Krebs Pigments and Chemical Company and other companies.[2] The material came in different seals, which varied in the content of zinc sulfide. Gold seal and Bronze seals contain 40-50% zinc sulfide, offering more hiding power and strength.[3] Although its popularity peaked around 1920, approximately 223,352 tons were produced in 1990. It is mainly used in paints, putty, and in plastics.[1]
