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.

  • Emulsifiers are substances that help stabilize mixtures of oil and water by reducing the surface tension at the interface of the two phases. Carrageenan serves this purpose effectively due to its ability to interact with both hydrophilic (water-attracting) and hydrophobic (water-repelling) molecules. When added to emulsions, carrageenan enhances the physical stability of oil-in-water or water-in-oil systems by forming a protective layer around dispersed droplets, preventing coalescence and separation. This functionality is particularly crucial in food products where texture and consistency are key to consumer acceptance.


  • Flavour Enhancer 635 is a compound that combines disodium guanylate (E627) and disodium inosinate (E631). Both components are naturally occurring nucleotides that intensify the umami flavor in food, which is often described as savory. Commonly found in a variety of processed foods such as snacks, sauces, and ready meals, E635 is favored by manufacturers because it enhances flavors without the need for excessive salt or sugars.

This pushback has led many food manufacturers to explore alternatives to E621, such as yeast extracts or natural umami sources like mushrooms and tomatoes.


  • On the flip side, the reliance on artificial preservatives has raised concerns among consumers who prefer natural alternatives. The movement towards clean label products has prompted some manufacturers to seek alternatives to preservatives like sodium sorbate. This shift is driven by consumer demand for transparency and a desire to avoid synthetic additives. As a result, there are now more options available that utilize natural preservatives, such as vinegar and essential oils, which offer similar benefits without the contentious nature of artificial chemicals.


  • Crops such as tomatoes, potatoes, carrots, and various fruits benefit significantly from potassium, leading to improved quality and shelf life. Insufficient potassium can result in symptoms such as yellowing of leaf edges, poor fruit quality, and increased susceptibility to diseases. Therefore, ensuring a balanced potassium supply through fertilizers like potassium sulphate is crucial for optimal crop performance.
