Glass bottle production process include: 

① raw material pre-processing. The massive raw materials (quartz sand, soda ash, limestone, feldspar, etc.) crushed, the wet raw material is dried iron-containing raw materials for iron treatment to ensure the quality of the glass. 

② with the preparation of materials. 

③ melting. The glass batch material is heated at a high temperature (1550-1600 ° C) in a pool kiln or a pool furnace to form a liquid glass that is uniform, bubble-free, and complies with forming requirements. ④ forming. The liquid glass into the mold to make the desired shape of glass products, such as flat, all kinds of utensils. 

⑤ heat treatment. Through annealing, quenching and other processes, to eliminate or produce the internal glass stress, phase or crystallization, and change the structural state of the glass.
