Titanium dioxide's unique characteristics stem from its crystal structure, which gives it a remarkable ability to scatter light effectively. As a result, it is a primary component in the paint and coatings industry, where it imparts whiteness, opacity, and gloss to paints, coatings, and inks. Its UV resistance also makes it ideal for outdoor applications, protecting surfaces from fading and degradation caused by sunlight exposure.

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.

Although barium sulfate is almost completely inert, zinc sulfide degrades upon exposure to UV light, leading to darkening of the pigment. The severity of this UV reaction is dependent on a combination of two factors; how much zinc sulfide makes up the pigments formulation, and its total accumulated UV exposure. Depending on these factors the pigment itself can vary in shade over time, ranging from pure white all the way to grey or even black. To suppress this effect, a dopant may be used, such as a small amount of cobalt salts, which would be added to the formulation. This process creates cobalt-doped zinc sulfide. The cobalt salts help to stabilize zinc sulfide so it will not have as severe a reaction to UV exposure.

  • Another significant advantage of ceiling mineral fiber is its ease of installation. These tiles are lightweight and can often be suspended using a grid system, which simplifies the installation process. Additionally, they are easy to maintain. Most mineral fiber ceiling tiles can be cleaned with a damp cloth or vacuumed to remove dust and dirt, ensuring that they remain in good condition with minimal effort.

  • While the benefits of drop down ceiling tiles are numerous, potential buyers should consider a few factors before making a decision. For instance, the height of the room can impact the choice of tiles; lower ceilings may require slimmer tiles to maintain a spacious feel. Additionally, while drop down ceilings are versatile, they may not be suitable for every environment, especially in places where high moisture levels are a concern, as some tile materials may not hold up well under such conditions.
