Which is better, high borosilicate glass or ordinary glass? ?

         High borosilicate glass (also known as hard glass), because of the thermal expansion coefficient of (3.3 ± 0.1) × 10-7 / K, it is also called "borosilicate glass 3.3". Borosilicate heat-resistant glass is a kind of "ripe glass", which is quite expensive and fully meets international environmental protection testing standards. 

       It is a special glass material with low expansion rate, high temperature resistance, high strength, high hardness, high light transmittance and high chemical stability. Because of its excellent performance, it is widely used in solar energy, chemical industry, pharmaceutical packaging, and electric light sources. , Craft jewelry and other industries. Its good performance has been widely recognized by various circles in the world, especially in the field of solar energy, and it has been widely used in developed countries such as Germany and the United States.

The difference between high borosilicate glass and ordinary glass is that the composition of high borosilicate glass is limited, so its heat resistance and appearance are better than ordinary glass.

For daily drinking, for safety reasons, glass should be preferred:

1. The glass does not contain organic chemicals during the firing process. When people drink water or other beverages in the glass, they do not need to worry about the chemicals being in the stomach, and the glass surface is smooth and easy to clean. Bacteria and dirt are not easy to breed on the wall of the glass, so drinking water from a glass is the healthiest and safest;

2, but other glass materials have hidden dangers. Colorful ceramics, especially the inner walls are coated with glaze. When the cup is filled with boiling water or drinks with high acidity and alkalinity, the toxic heavy metal elements such as lead in these pigments are easily dissolved in the liquid, and people drink the liquid with chemicals , It will cause harm to the human body. Plasticizers are often added to plastics, which contain some toxic chemicals. When a plastic cup is filled with hot water or boiling water, the toxic chemicals are easily diluted into water, and the internal microstructure of plastic has many pores. Among them, Hidden dirt, easy to breed bacteria if not cleaned;
