Glass bottle production process mainly includes:

① Raw material pre-processing. The massive raw materials (quartz sand, soda ash, limestone, feldspar, etc.) are crushed, the wet raw materials are dried, and the iron-containing raw materials are treated with iron removal to ensure the quality of the glass.

② Preparation of compound materials.

③ Melting system. The glass compound is heated at high temperature (1550~1600 degrees) in the pool kiln or pool furnace to form a uniform, bubble-free liquid glass that meets the molding requirements.

④ Forming. The liquid glass is put into the mold to make the glass products of the required shape, such as plates, various utensils, etc. ⑤ Heat treatment. Through annealing, quenching and other processes, eliminate or produce the internal stress of the glass, phase separation or crystallization, and change the structural state of the glass.
