1、 What is a double glass cup?

There are many types of glasses, generally divided into single-layer glasses, double-layer glasses, crystal glasses, glass office cups, glass mouth cups, etc. Double layer glass, Gu Mingsi, is a glass that is divided into two layers during production, which can provide insulation and prevent scalding during use. Its raw material is high borosilicate glass, food grade catering grade glass, which is fired at a high temperature of over. 600 degrees Celsius. It is usually made of high-precision silicon glass cup tubes, and the inner and outer tubes of different sizes are baked by technicians in a sealing machine

2、 Is the double-layer glass insulated?

Double layer glass cups mainly have insulation and insulation functions. At the same time, ice cubes can also be stored, and many glass cups produced by Guangjia have double layer ice bucket settings. The interlayer vacuum double layer cup is usually manually blown, and the middle layer is not vacuum at all. There is an air outlet at the outer bottom of the cup to discharge gas during the blowing process and prevent the cup from deforming and bursting. Seal the holes after production is completed. There is gas in the middle, and if it is a vacuum, the cup will make a loud noise when broken, and it will blow up glass fragments, causing injuries to people.

3、 What are the advantages of double-layer glass cups

1. Not easy to absorb other odors

During the production process of double-layer glass water cups, due to the special density of the materials, their ability to absorb and absorb other flavors is not strong. Therefore, even if you want to drink light water after brewing strong tea, you cannot smell the taste of brewing strong tea before drinking lighter water.

2. Friction resistance

During the production process of double-layer glass water cups, due to the high hardness of the material, the double-layer water cups produced are particularly resistant to friction. For those who have a dishwasher at home, the dishwasher can also directly clean the double-layer glass water cup

3. Good material

Compared to ordinary glass water cups, double-layer glass water cups use more sturdy materials, and the material of double-layer glass water cups is also relatively fine. The cup is less prone to water stains during use and is more convenient to clean.

4. Not easily cracked

Compared to single-layer glasses, double-layer glasses require higher craftsmanship. Due to the higher craftsmanship requirements, double-layer glasses are not as prone to cracking as single-layer glasses.

5. More unique appearance

In the process of making a double-layer glass water cup, there is a layer of glass inside and a layer of glass outside, so from the appearance, it looks better than single-layer glass, and its aesthetic value is more extensive than single-layer glass

6. Good insulation effect

Compared to single-layer glass water cups, double-layer glass water cups also undergo high-temperature melting during production. When hot water is added to the double-layer glass water cup, the insulation effect is much better than that of single-layer glass water cups

7. Preventing burns

If you want to buy yourself a glass water cup, it is recommended to buy a double-layer glass water cup. Compared to a single-layer glass water cup, a double-layer glass water cup will not burn hands if there is boiling water inside the water cup. If the water temperature is relatively high, a single-layer glass water cup is easy to burn hands.

4、 The difference between double-layer glass cups and single-layer glass cups

In a simple sentence, a double-layer glass cup has a vacuum between the two layers of glass, which can be insulated and not too hot to hold. Single layer glass does not have a vacuum layer in the middle, and the heat dissipates quickly. Pouring hot water can feel hot to the hands

Insulation time after covering: Double layer glass cup>Single layer glass cup

Suggestion: If you enjoy drinking warm water and always have a cold water cup, you can use a single layer of glass.
