The production process of glass bottles mainly includes: ① pre processing of raw materials. Crush blocky raw materials (quartz sand, soda ash, limestone, feldspar, etc.) to dry wet raw materials, and remove iron from iron containing raw materials to ensure the quality of glass. ② Batch preparation. ③ Melting. The glass batch is heated at high temperatures (1550-1600 degrees Celsius) in a tank or furnace to form a uniform, bubble free liquid glass that meets the molding requirements Forming. Put liquid glass into the mold to make the required shape of glass products, such as flat plates, various utensils, etc. ⑤ Heat treatment. By annealing, quenching, and other processes, stress, phase separation, or crystallization inside the glass can be eliminated or generated, as well as the structural state of the glass can be changed.
