How is glass made?
Glass is a material widely used in construction, home furnishings, technology and other fields, but many people do not know its manufacturing process. This article will introduce the production method of glass in detail, and combine the hot topics and hot content in the past 10 days to present you with a structured data report.
1. Basic glass manufacturing process
The manufacturing of glass is mainly divided into the following steps:
| steps | Description |
|---|---|
| Raw material preparation | The main raw materials are quartz sand (silica), soda ash (sodium carbonate) and limestone (calcium carbonate), accounting for approximately 70%, 15% and 10%. |
| melt | The raw materials are melted at high temperature (about 1500°C) to form a uniform glass liquid. |
| Forming | Molten glass is formed into flat glass or vessels through floatation, blowing, calendering, etc. |
| Annealing | Cool slowly to eliminate internal stress and improve the strength and stability of the glass. |
| processing | Carry out subsequent processing such as cutting, edge grinding, and coating as required. |
