glassware production process
Glassware production process include:
① pre-processing of raw materials. The raw materials (quartz sand, soda ash, limestone, feldspar, etc.) are pulverized to dry the damp raw materials, and the iron-containing raw materials are iron-treated to ensure the quality of the glass.

② with the material preparation.
③ melting. Glass batch in the pool or pool furnace for high temperature (1550 ~ 1600 degrees) heating, so that the formation of uniform, no bubbles, and meet the requirements of the liquid glass molding.
④ molding. The liquid glass is put into a mold to form a glass article of a desired shape, such as a plate, a variety of vessels, and the like.

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