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.

One of the main applications of titanium dioxide in paper is in the production of high-quality coated papers. Titanium dioxide is often added to the coating formulations to enhance the whiteness and brightness of the paper surface. This helps to improve the print quality of the paper, as it provides a smooth and even surface for ink to adhere to. The high opacity of titanium dioxide also helps to prevent show-through, making the printed text or images more vibrant and legible.

  • Threaded drill rods are essentially high-strength steel tubes with male and female threads at each end, allowing them to be screwed together to form a continuous drill string. The thread design varies, but typically includes API connections like box and pin threads, ensuring a secure and reliable connection during drilling operations. These threads not only facilitate assembly and disassembly but also transmit torque from the surface down to the, enabling rotation and drilling action.
  • The 'hex shank' refers to the shape of the bit's shaft, which is hexagonal rather than cylindrical. This design was primarily introduced to address the common issue of drill bits slipping in the drill chuck. The hex shank provides a more secure grip, reducing slippage and ensuring better control during drilling operations. It also allows for quick and easy changes without requiring a key, saving valuable time on the job.
  • Additionally, fiberglass stair treads are easy to clean and maintainfiberglass

  • Fiberglass grating is a kind of plate-shaped material with many spaces, which is made of glass fiber as a reinforcing material, unsaturated polyester resin as the matrix, and a special processing compound. It can be used as a structural material and used as a corrosive material. Environmental floors, trench covers, platforms, ship decks, stairs, plank roads, etc. It has the characteristics of corrosion-resistant, flame-retardant, non-magnetic insulation, bright colors, and a variety of styles.

  • One of the key advantages of FRP vessels is their high strength-to-weight ratio.
