Glass – Composition & Industrial Production

The chapter discusses glass as a composition, a production, and industrial use, and its flexibility as well as significance in the construction industry, electronics, and the everyday use of glass. Glass is a clear, non-crystalline solid that is mainly made of silica (SiO2) and other additives such as soda, lime, boron, and alumina to alter such characteristics as thermal expansion, permanence, and transparency. The chapter outlines the production processes in the industries such as batch preparation, melting, forming (float, blow, and pressing) and annealing that provide uniformity and minimize internal stresses. The various categories of glass including soda-lime glass, borosilicate, and safety glass are discussed together with their characteristics, composition, and use in the construction industry, laboratory equipments, electronics, and in the automobile sector. Another issue that is discussed in the chapter is the problem of quality control, minimization of flaws, energy and environmental involvement in large-scale production processes. Combining the knowledge gained through the theory with the practical manufacturing processes, the students acquire knowledge of glass chemistry, material properties, and industrial optimization, which will make them ready to work in the sphere of materials science, chemical engineering, industrial production, and product design. The chapter highlights the importance of glass to the contemporary technology, structural use and sustainable industrial processes.
