1. Will this glass explode when filled with boiling water? Some reviews say the glass is thin, so is it easy to break?

Answer: Thermally resistant borosilicate glass, compared to traditional sodium calcium glass (thick walled European crystal glasses), has a more compact molecular structure, and it only needs

A thinner thickness can achieve better strength, generally about 1.1mm, with a light and portable feel, yet still durable and strong. High boron.

Silicon glass has superior heat resistance and corrosion resistance compared to traditional glass, but it also has a higher production cost. It can withstand instantaneous temperature differences of -20℃ to 150℃, and can be placed in boiling water after freezing for 12 hours without any problem. Please rest assured to purchase.

Why does the cup mouth (the opening of the pot) always have a small protrusion?

这个疙瘩，在生产专业用语上称为"玻滴”，工艺行话叫做"爆口”。爆口处的节点是一个类似

The protrusions or small indentations on the glass nodules are the finishing parts of the hand-blown glass products, where excess glass solution is cut away after the complete molding process. This is a characteristic of handcrafted glass. By observing this point, you can tell whether the product you are purchasing is made by the hand-blowing technique. At the same time, the remaining mouth can also prevent the adhesion between the various glass accessories. Because the heat-resistant glass tea set"

It is often heated. If the components are absorbed after the heating process, the high pressure in the pot cannot be released.

The possibility of danger is high when the pressure difference between inside and outside reaches a certain extent.

3. When you look at the cup from the side with light, you can see a faint pattern of circles. When you knock on it, it feels different from ordinary glass. Why is that?

Answer: High-borosilicate glass, as a more advanced glass material, is widely used in various devices, as well as in Europe and the United States.the meal

Cookware production. The texture is slightly different from traditional sodium calcium glass. For the uniformity of the molding, the master craftsman uses a technique called "cold pressing" to create each piece.Blow molding

During the process, it is necessary to continuously rotate the glass embryo to form the pattern, which is a normal craft phenomenon characteristic of hand-made glass products.

Why is there a small dot at the bottom of a double-layer cup?

This process is similar to the inner lining of a thermos bottle, which is the point of closure. It is here that air can be discharged between the double-layer glass during the manufacturing process.

In addition, our company also spent more human, financial, and technical resources to create a hole-free double-layer cup, which does not have a bottom.

The one with the "receiving hole" is what we call a vacuum cup. This type of cup is made using a special technique that creates a vacuum inside the cup.

Air is sucked out, making the space between the double-layer glass a vacuum, thus preventing the occurrence of high-temperature and high-pressure expansion explosions! This type of cup has good insulation.

The effect and insulation performance of this cup are much better than that of ordinary double-layer cups. Its more powerful uses and special craftsmanship make this cup superior to ordinary double-layer cups.

The cost of the cup is much higher!

5. What kind of drinks can this cup hold?

This product is a household drinking vessel suitable for daily use as a beverage cup. It has double-layer insulation and keeps warm, making it highly decorative.
