The determination of sulfate in various matrices is a critical task for environmental monitoring, industrial process control, and quality assurance in chemical production. When present in high concentrations, sulfates can pose health risks and impact the ecosystem. However, the analytical challenge often lies not just in detecting the presence of sulfates but also in accurately quantifying them, especially when they are to be determined as titanium dioxide (TiO2). This article delves into the methodologies used to determine sulfate as TiO2, highlighting the complexities and nuances involved in such an analysis.

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.
