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.

The blending process is a critical step in the manufacturing, where zinc sulfide and barium sulfate are thoroughly mixed to ensure homogeneity. This is often done using specialized equipment like ball mills or attritors, which grind the particles to an ultrafine consistency, enhancing the pigment's opacity and whiteness This is often done using specialized equipment like ball mills or attritors, which grind the particles to an ultrafine consistency, enhancing the pigment's opacity and whiteness This is often done using specialized equipment like ball mills or attritors, which grind the particles to an ultrafine consistency, enhancing the pigment's opacity and whiteness This is often done using specialized equipment like ball mills or attritors, which grind the particles to an ultrafine consistency, enhancing the pigment's opacity and whitenesslithopone manufacturing process manufacturer.

Should a grade of lithopone be desired higher than the standard grade and another by-productas, for example, a forty-five*per= cent. grade of lithopone and barium chlorid the following process may be pi'acticed,\vhich, however, is quite analogous to the one already 10o described. Aqueous solutions of the ingredients are prepared as before, in these proportions: zinc sulfate, one hundred and sixty-one pounds; zinc chlorid, one hundred and thirty-six pounds, and barium sulfid, three hundred and thirty-eight pounds. Upon mixing these several solutions the lithopone will at once be precipitated in accordance with the following reaction:

In terms of market dynamics, China’s titanium dioxide industry has witnessed substantial growth over the past decade. The increasing demand from emerging sectors such as new energy sources and high-end manufacturing has propelled the industry forward. However, challenges like overcapacity and intense competition remain. To maintain a leading position, Chinese producers are focusing on improving product quality, expanding into high-value markets, and exploring international opportunities.
