Glass Production Process

1. Raw material preprocessing. Crush the bulk raw materials (quartz sand, soda ash, limestone, feldspar, etc.) to dry the wet raw materials, and remove iron from the iron-containing raw materials to ensure the quality of the glass.
2. Batch preparation.
3. Melting. The glass batch materials are heated to high temperature (1550~1600 degrees) in a tank kiln or crucible kiln to form a uniform, bubble-free liquid glass that meets the molding requirements.
4. Forming. Process liquid glass into products of required shapes, such as flat plates, various utensils, etc.
5. Heat treatment. Through annealing, quenching and other processes, the stress, phase separation or crystallization inside the glass is eliminated or generated, and the structural state of the glass is changed.
