Fiberglass, often referred to as fibreglass or glass fiber, is a composite material made from very fine fibers of glass. It is not a polymer by itself but is typically combined with a polymer matrix to create a composite material. The glass fibers are made from various types of glass depending upon the fiberglass use. These fibers are used to reinforce polymer products, leading to a material that is lightweight, extremely strong, and durable. The polymer, often a type of resin, acts as a glue that holds the glass fibers together and helps transfer stress between the fibers, enhancing the strength and flexibility of the composite material. Therefore, while fiberglass itself is not a polymer, it is an essential component in many polymer-based composite materials, providing structural reinforcement.

Reactive dyes are a class of highly colored organic substances, primarily used for tinting textiles. They directly bond with the fabric fibers through a chemical reaction, making the dye part of the fiber. This results in brilliant colors that are more resistant to washing and sunlight. Unlike other dyes that merely adhere to the fabric and can wash out over time, reactive dyes form covalent bonds with the material, ensuring the colors remain vibrant for longer. Introduced in the 1950s, they have become popular for dyeing cotton, wool, and other cellulose-based fabrics due to their excellent colorfastness. Their application varies from dip-dyeing, batik, to machine dyeing, providing versatility for different design needs. However, the dyeing process requires careful control of conditions such as temperature and pH to achieve the desired outcomes. The environmental impact is a consideration as well, with advances in dye formulation and treatment technologies improving their sustainability profile.
Ferric iron oxide powder, or Fe2O3, is commonly used in pigments, coatings, and various industrial processes. It is available from chemical suppliers, online marketplaces like Amazon and eBay, and specialized retailers in scientific supplies. When purchasing, consider purity levels, particle size, and whether you need it for a specific application such as ceramics or paint production. Some well-known chemical supply companies include Sigma-Aldrich, Fisher Scientific, and VWR. Additionally, local art supply stores might carry it in smaller quantities for pigment purposes. Always ensure you're buying from a reputable supplier to guarantee the quality and safety of the chemical.
