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. Eliminate or produce stress, phase separation or crystallization within the glass, and change the structural state of the glass by annealing, quenching and other processes.

The main features are: non-toxic, tasteless; transparent, beautiful, glass bottle

Good barrier, airtight, rich and common raw materials, low price, and can be used for many times. And it has the advantages of heat resistance, pressure resistance and cleaning resistance, which can be sterilized at high temperature and stored at low temperature.
