Glass manufacturing is the process of creating glass products from raw materials like silica sand, soda ash, and limestone. These ingredients are mixed and heated in a furnace at high temperatures until they melt into a liquid form. Once melted, the glass can be shaped into various items, such as bottles, windows, and jars, using molds or blowing techniques. After shaping, the glass is cooled slowly in a process called annealing, which helps prevent cracks and ensures durability. Finally, the finished products are inspected for quality and packaged for distribution. This industry plays a vital role in everyday life, providing essential items for homes and businesses.
