Is High Borosilicate Glass Water Bottle Safe To Drink Water?

People often ask if drinking water with a high borosilicate glass water bottle is poisonous? In fact, this is a misunderstanding that we are not familiar with high borosilicate glass. High borosilicate glass (also known as hard glass) is made by using the conductive characteristics of glass in the high temperature state, melting the glass through heating inside the glass, and processing by advanced production process. It is a kind of special glass material with low expansion rate, high temperature resistance, high strength, high hardness, high light transmittance and high chemical stability, which is harmless to human body. It is used in our common special glass turntable for microwave oven, heat-resistant teapot and teacup, etc. Nowadays, many glass water bottles are made of high borosilicate glass. Compared with traditional glass, this kind of water bottle is more resistant to high temperature and low temperature, and is recognized as a safer glass material.

 

Why is it said that high borosilicate glass water bottle is safer? Because the high borosilicate glass water bottle has a very low coefficient of thermal expansion, about one third of the ordinary glass. This feature can reduce the influence caused by temperature gradient stress, so it has stronger fracture resistance. Because its shape deviation is very small, it also makes it an indispensable material in telescopes and mirrors. Although it has a strong thermal shock resistance, it does not mean that it will not crack due to the rapid change of temperature. The normal glass fracture is comminuted. The cracks of high borosilicate glass water bottle are often larger, which also makes the damage coefficient smaller to some extent.

 

So in life, how can we distinguish whether it is made of high borosilicate glass water bottle? Do you remember the test tubes commonly used in junior high school when doing chemical experiments? It is made of high borosilicate glass, because the test tube of high borosilicate glass has very high chemical stability and can be heated directly under high temperature. The common high borosilicate glass water bottle we buy everyday has high transparency, light weight and thin bottom. Generally, the glass water bottle with thick bottom is not made of high borosilicate; most of the double-layer glass water bottles we often see are made of high borosilicate heat-resistant glass. The main process of high borosilicate heat-resistant glass water bottle is manual blowing and semi-automatic assembly line, which costs more than ordinary glass. Moreover, high borosilicate glass water bottle has higher transparency and smoother hand feel than ordinary glass. Even the baby's milk bottle is made of high borosilicate glass, so we can imagine its safety. Now, do you still ask that drinking water from high borosilicate glass water bottle will be toxic?
