Chinese manufacturers adhere to strict quality control standards, ensuring that their anatase TiO2 meets international specifications. The 99.6% purity level is achieved through sophisticated purification techniques, including leaching, precipitation, and calcination processes. These methods remove impurities such as iron, sulfur, and organic compounds, resulting in a product with exceptional whiteness, brightness, and dispersion properties.

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.

Rutile titanium dioxide, identified by its unique crystal structure, is renowned for its exceptional brightness and high refractive index. These properties are further enhanced in the R-906 grade, which is meticulously processed to provide superior performance in printing inks. The R-906 pigment boasts a uniform particle size distribution, ensuring optimal coverage and consistent color reproduction. Its fine particles seamlessly blend with the ink's binder system, resulting in a smooth, homogeneous mixture that yields crisp, vivid prints.
