Double Wall Glass Cup


What is a double wall glass cup

 

There are many kinds of glasses, generally divided into single wall glass, double wall glass, crystal glass, etc. Double layer glass is divided into two layers when the glass is made, which can play the role of heat insulation and scald prevention when used. Its raw material is high borosilicate glass, food grade glass, after more than 600 degrees of high temperature firing. It is usually made of high borosilicate glass tube. The inner and outer tubes are baked by technicians under the sealing machine.

 

Is double glass insulated?

 

Double glass is mainly used for heat preservation and insulation. The interlayer vacuum double-layer cup is usually blown by hand. The lattice layer in the middle layer is not vacuum at all. There is an air outlet at the bottom of the outer layer of the cup, so as to exhaust gas during the blowing process and prevent the cup from deformation and cracking. Seal the hole after production. There's gas in the middle. If it's vacuum, the broken cup will make a big noise, and it will blow up the glass pieces, which is easy to hurt people.


Characteristics of double glass

 

1. Materials: made of high-quality high borosilicate crystal glass pipe, with high transparency, wear resistance, smooth surface, easy cleaning, health and hygiene.

 

2. Structure: double layer heat insulation design, keep the temperature of tea soup, not hot, more convenient to drink.

3. Process: made by firing at a high temperature of more than 600 degrees, has strong adaptability to temperature change, not easy to burst.

 

4. Hygiene: food grade standard, can hold hot water, tea and other drinks with high temperature of 100 ℃, no peculiar smell and no smell.

 

5. Leakproof: the cup cover and sealing ring meet the medical level safety standards, which can effectively leak proof.

 

6. Suitable for tea drinking: green tea, black tea, Pu'er tea, flower tea, fruit tea, etc.

 

The difference between double glass and single glass

 

A simple sentence is: the middle of double wall glass cup is vacuum, which can be heat insulated and not hot. There is no vacuum layer in the middle of the single-layer glass, so the heat is dissipated quickly. Pouring hot water will burn your hands.

 

Heat preservation time after capping: double glass > single glass

 

Suggestion: if you like warm water and always have a cold water cup, you can use a single layer glass.

 

If the above conditions are not met, double wall glass cup is recommended. Can prevent burns!
