When it comes to glass, the first key word you think of is “fragile”. Yes, this is one of its characteristics, but you may not know its more advantages. With the development of science and technology, people give full play to the value of this transparent and fragile material, make up for its shortcomings by adjusting its properties, and make it into various shapes, And making glasses and double-layer glasses that adults have been using.
This paper will introduce how the glass is produced. Before that, we will first introduce the production technology of double-layer glass.

1、 Double glass process
The double-layer glass is mainly used for heat preservation and heat insulation. At the same time, it can also save ice. We produce double-layer ice buckets. The lattice vacuum double-layer cup is generally blown manually. The middle lattice is not vacuum at all. There is an air outlet at the bottom of the outer layer of the cup in order to exhaust gas during the blowing process and prevent the cup from deformation and cracking. Seal the hole after production. There is gas in the middle. If it is a vacuum, the broken cup will make a big noise and blow up glass fragments, which is easy to hurt people. When you buy double-layer products, there will be sealing holes under them. The sealing hole of the double-layer pot is usually under the handle.
The production is relatively complex. Generally, 5 to 9 people can produce normally.

2、 How are glasses made
The glass is usually made of high borosilicate glass and fired at a high temperature of more than 600 degrees.
There are manual blowing, machine blowing and machine pressing; Blowing steps are as follows
1: Support wire;
2: Blow the ball;
3: Skin opening;
4: Liner opening back sealing;
5: Interface;
6: Back cover;
7: Labeling;
8: Annealing.
