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.

  • The byproducts of FGD, such as gypsum, can often be recycled and used in products like wallboard or concrete, promoting a more sustainable approach. However, the disposal of these byproducts also requires careful management to prevent environmental impacts.
  • Finishing: All cut surfaces should be coated with resin to prevent corrosion of glass fibers. A light coating of two-part resin system or urethane spray paint is satisfactory.

  • Lightweight and easy to install, fiberglass stair treads are available in both molded and pultruded types, to match the fiberglass floor grating platforms. Fiberglass material stair tread covers are made from a molded glass and resin system that is corrosion and impact resistant, fire retardant, and non-conductive. They provide a cost effective, slip-resistant, protective surface for concrete, metal and wood steps. For more on fiberglass stair treads and stair tread covers, click here.

  • GRP cars are also known for their innovative technology. These cars are often outfitted with advanced computer systems, telemetry data recorders, and onboard cameras that allow teams to monitor and optimize performance in real-time. This data is crucial for making strategic decisions during races, such as pit stops, tire changes, and fuel management.
  • The manufacturing process of FRP rectangular tubes involves pultrusion, a technique that impregnates continuous glass fiber rovings with resin and then pulls them through a heated mold to form the desired shapefrp rectangular tube. This process ensures consistent quality, precise dimensions, and the ability to produce tubes in lengths up to several meters.
  • One of the key advantages of fiberglass tanks is their resistance to corrosion. Unlike metal tanks, which can corrode over time when exposed to certain chemicals or saltwater, fiberglass tanks maintain their integrity even in the most challenging environments. This makes them particularly useful in wastewater treatment, where acids and alkalis are common, and in marine applications where saltwater corrosion is a constant concern.
