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 removed from iron to ensure the quality of the glass.

Glass bottle production process mainly includes:

① Pre-processing of raw materials. 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 removed from iron to ensure the quality of the glass.

② Preparation of batch materials.

③ Melting. The glass batch 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. Put the liquid glass into the mold to make the required shape of the glass products, such as flat plates, various utensils, etc.

⑤ Heat treatment. Through annealing, quenching and other processes, the internal stress, phase separation or crystallization of the glass is eliminated or generated, and the structural state of the glass is changed.
