The design of double-layer glass cups not only prevents scalding, but also has a certain insulation effect, which is one of the reasons why double-layer glass cups are now widely used. So why do double-layer glass cups have scalding and insulation characteristics? Let's take a look together!

Firstly, the double-layer glass cup is heat-resistant and insulated because it adopts vacuum insulation technology. Under vacuum conditions, it can prevent heat from transferring to the outside, thereby achieving the effect of preventing scalding and insulation. However, the insulation effect of double-layer glass cups is different from that of real insulated cups, because the mouth of double-layer glass cups will dissipate heat.

Secondly, the sealing performance of double-layer glass cups also affects their insulation effect. Double layered glass cups with good sealing have better natural insulation effect. To test its sealing, first twist off the cup lid to see if it fits perfectly with the cup body. Then add boiling water to the cup and invert it for two to three minutes to see if water seeps out. If the glass does not leak water, it indicates good sealing.

The anti scalding and insulation effect of double-layer glass cups is very practical, as it can ensure the temperature of the tea without being unable to be taken down like insulated cups. Of course, the market prospects for double-layer glass cups are very promising, not only for these two reasons, but also for many other characteristics that have contributed to the important position of double-layer glass cups in the daily necessities industry.
