In summary, the Food Directorate's position is that there is no conclusive scientific evidence that the food additive TiO2 is a concern for human health. This is based on a review of the available scientific data relevant to food uses of TiO2. However, we will continue to monitor the emerging science on the safety of TiO2 as a food additive and may revisit our position if new scientific information becomes available.
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.

Float glass itself, invented in the mid-20th century, involves a process where molten glass is floated on molten tin to create a smooth, uniform sheet. The addition of colorants to this process transforms the ordinary into the extraordinary. Colorants, derived from metal oxides, are infused into the molten glass, producing a multitude of hues. Common colorants include cobalt for blue, chromium for green, and manganese for violet. The beauty of coloured float glass lies not only in its vivid colors but also in its ability to interact with light, creating dynamic visual effects that vary throughout the day.
