The author thanks Marco Leona, Scientist-in-Charge of the Department of Scientific Research at the Metropolitan Museum of Art for conducting fluorescence spectrometry on Wheel of Fortune and a valuable discussion of the research, as well as Silvia Centeno, Research Scientist at the Metropolitan Museum of Art, who performed Raman analysis on the watercolors and also contributed her insight. The phenomenon of the phosphorescing lithopone was originally discovered during the author's fellowship in the Sherman Fairchild Center for the Conservation of Works on Paper, funded by the Andrew W. Mellon Foundation. The author thanks all her colleagues for their ideas and support during the research of this paper, and special thanks to Rachel Mustalish for her assistance in editing this work.

  • Subsequently, barium sulfate, another crucial ingredient, is derived from barite, a naturally occurring mineral rich in barium. The barium sulfate is then mixed with the synthesized zinc sulfide in precise proportions to create the desired lithopone pigment. The mixture undergoes a series of processes, including grinding and classification, to achieve the required particle size distribution and enhance its performance characteristics.
  • In the cosmetics industry, titanium dioxide is used as a sunscreen agent to protect skin from harmful UV rays. It is also used in makeup products such as foundations and powders to provide a natural-looking coverage and a radiant finish. The micronized form of titanium dioxide is particularly effective at absorbing UV light, making it a popular choice among consumers who are concerned about sun protection.
