Some food products will include titanium dioxide on their nutrition label. But again, it can be hard to tell for those who don't list the ingredient. 

The market for anatase titanium dioxide has expanded significantly over the years, driven by growing demand from various sectors. Manufacturers are now focusing on optimizing the production processes to enhance the quality and performance of anatase TiO2. This includes advancements in synthesis methods to produce nanoparticles with improved dispersion and stability. Companies are investing in research and development to innovate new applications, particularly in the fields of renewable energy and sustainable materials.

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.
