1、What is the function of double wall glasses?

Double layer glass mug use the principle of double-layer structure, which enhances the comfort of the glass and also improves the heat preservation function of the glass. In addition to the humanized design, double wall glass also has a good aesthetic value. The transparent material combined with the two-layer structure almost sublimates tea drinking into a dynamic artistic act.

Many glass manufacturers produce double-layer ice buckets. Vacuum double-glazed glasses are usually hand-blown. The double-layered glass provides thermal insulation and can also store ice. During the blowing process, if the middle layer is not a vacuum, the outer layer of the glass has a vent hole. This is to vent the gas out of the glass to prevent it from deforming and exploding. After the production is finished, the hole is sealed. So there is gas in the middle of the two layers

2、Advantages of double wall glasses

1）It is not easy to absorb other flavors.

In the process of making a double wall glass mug, due to the special fineness of the material, the adsorption ability of other flavors is not strong. Drinking light tea also can not smell the taste of the previous strong tea, even if you just drank a strong tea.

2) Durable

In the process of making the double-layer glass mug, the special double-layer mug can resist friction due to the high hardness of the material. For those who have a dishwasher at home, the dishwasher can also be cleaned directly.  

3）Good high borosilicate material

Double-layer glasses are stronger than ordinary glasses. The material used in double-layer glass is stronger, the cup is not easy to hang water during use, and it is easy to clean.  

4) Not easy to crack

Double-layer glass has higher technical requirements than double-layer glass. Due to the higher technological requirements, double-layer glass is not as prone to cracking as single-layer glass.

5）Unique appearance - high-end, elegant

In the process of making double-layer glass, there is a layer of glass inside and a layer outside, so it looks better than single-layer glass in terms of appearance and has a wider aesthetic value than single-layer glass.

6) Heat or cold resistant

They are made of high borosilicate glass, and the applicable temperature is -20°C~150°C.   

If you want to buy a glass for yourself, it is recommended to buy a double-layer glass. If there is boiling water inside the glass, the double-layer glass will not be hot if there is water. But a single-layer glass is easy to scald if the temperature is too high.

The double glass design greatly reduces the thermal conductivity of the cup, which can effectively play the role of insulation and anti-scaling when used. Insulated cups can keep cold drinks cold and hot drinks hot, while the outer surface always feels comfortable to the touch.

7) Food safety

Double-walled glass is food-grade standard, can hold hot water, tea, carbonic acid, fruit acid and other drinks, acid corrosion resistance.
