The production process of glass bottles mainly includes: ① Raw material pre-processing. Crush the bulk raw materials (quartz sand, soda ash, limestone, feldspar, etc.) to dry the wet raw materials, and remove the iron-containing raw materials to ensure the quality of glass. ② Preparation of batch materials. ③ Melting. The glass batch material is heated at a high temperature (1550 ~ 1600 degrees) in the pool kiln or furnace to make it form a uniform, non-bubble, and liquid glass that meets the molding requirements. ④Forming. Put the liquid glass into the mold to make the glass products of the required shape, such as flat plates and various utensils. ⑤ Heat treatment. Through annealing, quenching and other processes, the stress, phase separation or crystallization inside the glass is eliminated or generated, and the structural state of the glass is changed.
