This article discusses the discovery of phosphorescent lithopone on watercolor drawings by American artist John La Farge dated between 1890 and 1905 and the history of lithopone in the pigment industry in the late 19th and early 20th centuries. Despite having many desirable qualities for use in white watercolor or oil paints, the development of lithopone as an artists' pigment was hampered by its tendency to darken in sunlight. Its availability to, and adoption by, artists remain unclear, as colormen's trade catalogs were generally not explicit in describing white pigments as containing lithopone. Further, lithopone may be mistaken for lead white during visual examination and its short-lived phosphorescence can be easily missed by the uninformed observer. Phosphorescent lithopone has been documented on only one other work-to-date: a watercolor by Van Gogh. In addition to the history of lithopone's manufacture, the article details the mechanism for its phosphorescence and its identification aided by Raman spectroscopy and spectrofluorimetry.

Another approach utilizes titrimetry, where a standard solution of a titrant, such as lead perchlorate or barium perchlorate, is used to react with the sulfate ions. The endpoint of the titration is determined either by a color change indicator or more sophisticated instrumentation like a potentiometric titrator The endpoint of the titration is determined either by a color change indicator or more sophisticated instrumentation like a potentiometric titrator The endpoint of the titration is determined either by a color change indicator or more sophisticated instrumentation like a potentiometric titrator The endpoint of the titration is determined either by a color change indicator or more sophisticated instrumentation like a potentiometric titratordetermination of sulphate as tio2. The volume of titrant used corresponds to the concentration of sulfate in the sample. Again, a stoichiometric calculation converts this to TiO2 content.
