High borosilicate glass is made by using the properties of glass to conduct electricity at high temperatures, and by heating inside the glass to achieve glass melting, and processed by advanced production technology. It is a special glass material with low expansion rate, high temperature resistance, high strength, high hardness, high light transmittance and high chemical stability. It is harmless to the human body. It is used for our common microwave oven special glass turntables, heat-resistant Teapot and cup, double layer high borosilicate glass cup, etc.

Many double layer high borosilicate glass cups on the market are made of high borosilicate glass, which is more resistant to high and low temperatures than traditional glass, and is recognized as a safer glass material. Let's take a look at the characteristics of double layer high borosilicate glass cup.

1. In terms of materials, the double layer high borosilicate glass cup is made of high-quality high borosilicate glass tube, which is extremely transparent, wear-resistant, smooth surface, easy to clean, healthy and hygienic.

2. In terms of structure, the double layer high borosilicate glass cup is designed with double-layer heat insulation, which not only maintains the temperature of the tea soup, but also makes it easier to drink. This is a significant feature that is different from single-layer glass cups.

3. In terms of technology, the double layer high borosilicate glass cup is fired at 600°C. It has strong adaptability to temperature changes and is not easy to burst. Even if you drink boiling water at 100°, it is not a problem.
