High borosilicate glass is a special glass material with low expansion rate, high temperature resistance, high hardness, high strength, high light transmittance and chemical stability, so high borosilicate glass cups are also very popular, but people don't know how to distinguish high borosilicate glass cups

Let me introduce it to you.
1. You can put the cup in the refrigerator for 24 hours, take it out and pour 100-degree hot water on it. If it bursts, it is definitely not high borosilicate glass.
2. High borosilicate glass cups have better transparency, more delicate cup body, and smoother feel. High temperature resistance and resistance to sudden cold and heat are the biggest characteristics of high borosilicate glass products.
3. Glass cups are cups made of glass raw materials. Usually the raw material is high borosilicate glass, which is fired at a high temperature of more than 600 degrees. It is a new type of environmentally friendly tea cup, which is increasingly favored by people.
