Résumé–Cet article traite de la découverte de lithopone phosphorescent sur des dessins à l'aquarelle, datés entre 1890 et 1905, de l'artiste Américain John La Farge et de l'histoire du lithopone dans l'industrie des pigments à la fin du 19e et au début du 20e siècle. Malgré de nombreuses qualités souhaitables pour une utilisation en tant que blanc dans les aquarelles et les peintures à l'huile, le développement du lithopone comme pigment pour artistes a été compliqué de par sa tendance à noircir lorsqu'il est exposé au soleil. Sa disponibilité et son usage par les artistes demeurent incertains parce que les catalogues des marchands de couleurs n'étaient généralement pas explicites à indiquer si les pigments blancs contenaient du lithopone. De plus, lors d'un examen visuel, le lithopone peut être confondu avec le blanc de plomb et sa phosphorescence de courte durée peut facilement être ignorée par l'observateur non averti. À ce jour, le lithopone phosphorescent a seulement été documenté sur une autre œuvre: une aquarelle de Van Gogh. En plus de l'histoire de la fabrication du lithopone, cet article décrit le mécanisme de sa phosphorescence et son identification à l'aide de la spectroscopie Raman et de la spectrofluorimétrie.

  • A gully grid, often referred to as a drain cover or drain grate, is designed to cover stormwater drainage pits. Its primary purpose is to allow rainwater and surface runoff to enter the drainage system while preventing larger debris from clogging the pipes. Gully grids can be made from various materials such as plastic, concrete, or metal, with the latter being favored for its strength and longevity.


  • Maintenance is also simplified with recessed covers. Cleaning urban infrastructure is necessary to maintain public health and aesthetic standards. With recessed designs, dirt and debris tend to accumulate less around the cover, making it easier for maintenance crews to perform their duties without extensive cleaning.


  • One of the primary reasons for the prevalence of round recessed manhole covers is their functional design. The round shape eliminates the possibility of the cover falling into the manhole, a risk associated with square or rectangular covers. Regardless of the orientation, a round cover cannot be accidentally dropped into the opening, thereby promoting safety for pedestrians and vehicles alike.


  • Manholes are usually round, primarily because roundness is the best shape to resist the compression of the earth; covers are round because they are easier to manufacture than square or rectangular shapes, they are easier to move by rolling, and they can't fall into the opening.[5] But in the United Kingdom they are nearly always square, or rectangular, in shape, at least at street level. Manholes can also be found in a triangular shape (e.g. in Cambridge, and surrounding villages).[6]
