You may be taking a second look at your favorite candy after hearing this week's news about titanium dioxide. Recently, a lawsuit was filed against Mars, Inc. based on claims that the manufacturer's popular Skittles candy is unfit for human consumption. The class-action lawsuit, filed in U.S. District Court for the Northern District of California in mid-July, alleged that the candy contained heightened levels of a known toxin called titanium dioxide — a food additive that the company previously pledged to phase out from their products in 2016, according to the Center for Food Safety.

  • 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.

  • What is Galvanized Rope?


  • Shijiazhuang Iron and Steel A Pillar of Industrial Growth


  • When it comes to securing roofs with unwavering strength and resilience, one essential tool that stands out in the realm of construction and roofing is the BWG9X2.5% rubber washer roofing nail. This specialized fastener not only ensures a firm grip but also adds an extra layer of protection against weather elements.
  • The 1% 201% 4% fiberglass rods are also lauded for their versatility. They come in various grades and thicknesses, enabling tailor-made solutions for specific applications. For instance, in the construction realm, they can be used as reinforcements in concrete, providing the necessary structural support while keeping the overall weight down. In the sports industry, their lightweight nature and flexibility make them perfect for applications such as tent poles and sporting goods where both strength and portability are required.


  • Iron wire mesh fences have become an increasingly popular choice for both residential and commercial properties due to their durability, versatility, and aesthetic appeal. This type of fencing is made from high-quality iron wire that is woven to create a strong, interlocking design, making it an ideal solution for various fencing needs. In this article, we will explore the benefits of iron wire mesh fences, their applications, and why they are a worthy investment for property owners.


  • Rod structures comprising 3% fiberglass content are typically lighter and more flexible compared to their 4% counterparts. This flexibility makes them ideal for applications where some degree of bendability is required, such as in the manufacturing of fishing rods or lightweight frameworks in various engineering projects. The increased flexibility also reduces the risk of breakage under stress, making them suitable for temporary or dynamic applications.


  • Once the welding is complete, the mesh is subjected to stringent quality control measures. This includes examining the weld integrity, checking for sharpness and ensuring that the dimensions meet industry standards. After passing these tests, the welded razor mesh is coated with a protective layer, further enhancing its resistance to environmental factors.

  • The installation of a 750-gallon fiberglass septic tank should always be carried out by a licensed professional. The process begins with careful site assessment to determine the best location for the tank, taking into consideration factors like soil type, distance from water sources, and the local building codes. Once the site is determined, excavation is performed to create a space for the tank.

  • Cost is another consideration in the nail versus screw debate. Typically, nails are less expensive than screws, making them a budget-friendly choice for large quantities. However, the ultimate cost can depend on specific projects, prices varying by materials and project size.


  • Purchasing Considerations


  • The manufacturing process of this wire mesh begins with selecting high-quality wire, typically made from stainless steel or galvanized iron to resist corrosion. These wires are then woven in a crisscross pattern and welded at each cross point to ensure structural integrity. Unlike other types of mesh that may use knots or twists, the welding technique provides an exceptionally strong bond that can withstand heavy loads and harsh environments.
  • Another advantage of China wood screws is their corrosion resistance. These screws are often coated with a protective layer that helps prevent rust and corrosion, ensuring that they remain strong and reliable over time. This makes them ideal for outdoor or high-moisture environments where other types of screws may fail.
