1. Will this kind of glass be fried with boiling water? After reading the comments, some people say that the glass is thin, is it easy to break?

Answer: Compared with traditional soda lime glass (thick-walled European crystal glasses), heat-resistant borosilicate glass has a closer molecular structure. Only

A smaller thickness can achieve better strength. Generally, the thickness is about 1.1mm, which is light and durable. High Boron

the heat resistance and corrosion resistance of silica glass are incomparable to traditional glass, and the production cost is also higher. The instantaneous temperature difference is-20 ℃-150 ℃, and there is no problem to put boiling water after 12 hours of freezing. Please rest assured to buy.

2. Why does the cup mouth (kettle mouth) have a bulge?

This pimple is called "glass drops" in the professional language of production, and the jargon of craft is called "seam slippage". The node at seam slippage is similar

the bulge or small notch of glass bumps is the finishing part of the excess glass solution cut off after the handmade glass products are completely formed. It is a feature of handmade glass. Through this point, you can distinguish whether the purchased product is a manual blowing process. At the same time, leaving the closing port in the kettle mouth (cup mouth) can also prevent the absolute suction between the glass accessories. Because heat-resistant glass tea set

it is often heated. If the high air pressure in the kettle cannot be released during the heating process after the parts are absolutely absorbed,

danger is likely to occur after the pressure difference between internal and external air reaches the degree.

3. The cup body looks at the light, and there is a faint circle of texture. It doesn't feel like ordinary glass when knocked. Why?

Answer: High Borosilicate Glass, as a more advanced glass material, is widely used in chemical medical equipment, as well as Europe and America. Meal

kitchen tools. The texture is slightly different from the traditional soda lime glass. Handmade glassware, in order to form evenly, the master blowing

during the process, it is necessary to continuously rotate the glass embryo to form a stretch pattern, which is a unique normal process phenomenon of handmade glass products.

4. Why is there a small dot at the bottom of double-layer Cup?

This process is similar to the inner container of the thermos bottle, which is the closing point. Here, the air between the double-layer glass can be discharged during the manufacturing process. Another

besides, our company also spent higher manpower and financial resources and technology to make non-porous double-layer Cup, which is not available at the bottom of the Cup.

Closed hole, this is what we call vacuum cup. This kind of cup uses a special process to empty the Cup during the production process.

If the gas is extracted and the double glass becomes a vacuum, there will be no high temperature and high pressure expansion explosion! Insulation of this kind of cup

the effect and heat preservation effect are much better than the ordinary double-layer Cup. More powerful use and special craftsmanship make this Cup better than ordinary double layer

the cost of the Cup is much higher!

5. What is this cup suitable for drinking?

This product belongs to daily household drinkware and is suitable for daily drinking and beverage cups. It is double-layer heat insulation and heat preservation, which is very ornamental.
