Glass bending is a process used to shape glass into various forms by applying heat. This technique involves heating the glass to a temperature where it becomes pliable, allowing it to be molded into curves or angles. The bending can be done using different methods, such as using a bending furnace or a mold, depending on the desired shape and thickness of the glass. Once the glass is heated and shaped, it is gradually cooled to prevent stress and ensure durability. This process is commonly used in the production of items like glass doors, windows, and decorative pieces, making it an essential technique in the glass manufacturing industry.
