How is glass made?

The main raw materials for glass production are glass forming agents, glass modifiers and glass intermediates, and the rest are auxiliary raw materials. The main raw materials are oxides, intermediate oxides and out-of-network oxides introduced into glass to form a network; Auxiliary raw materials include clarifier, flux, opacifier, colorant, decolorant, oxidant and reducing agent.

The glass production process mainly includes: ① raw material pretreatment. Bulk raw materials are crushed, wet raw materials are dried, and iron-containing raw materials are removed to ensure the quality of glass. (2) Batch preparation. (3) melting. The glass batch is heated at high temperature in the tank kiln or crucible kiln to form uniform and bubble-free liquid glass that meets the molding requirements. ④ molding. Processing liquid glass into products with required shapes, such as flat plates and various utensils. ⑤ Heat treatment. Through annealing, quenching and other processes, the internal stress, phase separation or crystallization of glass are eliminated or produced, and the structural state of glass is changed.
