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.

Anatase titanium dioxide, a crystalline form of titanium dioxide, is widely recognized for its unique properties and diverse applications. Produced by specialized manufacturers around the globe, anatase titanium dioxide plays a crucial role in numerous industries, including paints, cosmetics, photocatalysts, and solar cells. Its significance stems from its high refractive index, strong ultraviolet absorption capacity, and excellent stability.The European Commission banned titanium dioxide as a food additive in the EU in 2022 after the European Food Safety Authority (EFSA) conducted an updated safety assessment of E171 and concluded the panel could not eliminate concerns about its genotoxicity.
Another notable supplier is Company B, who specializes in customized solutionsWe use titanium dioxide as a colourant in some home care products, including in laundry detergents, dishwasher tablets and toilet blocks.
No. EFSA’s role was limited to evaluating the risks linked to titanium dioxide as a food additive. This included an assessment of relevant scientific information on TiO2, its potential toxicity, and estimates of human dietary exposure. Any legislative or regulatory decisions on the authorisations of food additives are the responsibility of the risk managers (i.e. European Commission and Member States).
Innovative automation and digitalization technologies are also transforming the white titanium dioxide industry. Smart factories equipped with IoT devices, sensors, and AI algorithms optimize production processes, enhance quality control, and ensure consistent product quality. These advancements not only boost productivity but also create safer working environments for employees. Titanium dioxide, also known as TiO2, is a widely used pigment and catalyst in various industries. It's renowned for its exceptional brightness, high refractive index, and excellent chemical stability. Due to these properties, TiO2 has found extensive applications in paints, plastics, papers, inks, food colorants, sunscreens, and more. As demand for this versatile material grows, understanding the landscape of TiO2 manufacturers becomes increasingly important. In conclusion, cheap barium sulfate superfine is not just an economical choice; it is a strategic material that optimizes performance while minimizing costs. Its versatility and broad range of applications demonstrate its value in today's industries. It underscores the importance of balancing affordability with functionality, highlighting the potential of seemingly 'cheap' materials to make a big impact in various sectors. With continued advancements in processing technologies, the role of cheap barium sulfate superfine is likely to expand even further, solidifying its position as a reliable and cost-effective industrial staple.Kronos Worldwide, an expert in titanium dioxide production, offers value-added services and innovative solutions to their clientele. Their range of products includes those designed for environmental and sustainability concerns.
In addition to Skittles, other candies that contain titanium dioxide include Nice! mints, Trolli sour gummies and Ring Pops, according to Environmental Working Group.
In the paint industry, titanium dioxide is extensively used as a pigment due to its high refractive index, which provides excellent hiding power and brightness. It is also known for its weather resistance and stability under various environmental conditions, making it suitable for both interior and exterior applications It is also known for its weather resistance and stability under various environmental conditions, making it suitable for both interior and exterior applications
