Is high borosilicate glass safe to drink water?
People often ask whether drinking water with high borosilicate glass can be toxic? In fact, this is a misunderstanding that everyone is not familiar with high borosilicate glass. High borosilicate glass (also known as hard glass), is the use of glass at high temperature conductive characteristics, by heating inside the glass to achieve glass melting, through advanced production technology processing.
It is a special glass material with low expansion rate, high temperature resistance, high strength, high hardness, high light transmittance and high chemical stability, which is not harmful to the human body, and is used for our common microwave oven special glass turntable, heat-resistant teapot cups and so on. Many 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.
Why is high borosilicate glass safer? Because high-borosilicate glass has a very low coefficient of thermal expansion, about one-third of that of ordinary glass. This feature better reduces the impact of temperature gradient stress, resulting in stronger fracture resistance. Because its shape deviation is very small, this also makes it an essential material in telescopes and mirrors. Although its thermal shock resistance is strong, it does not mean that it will not be broken due to rapid changes in temperature, normal glass breakage is comminuted, and the cracks of high borosilicate glass are often larger, which also makes the damage coefficient smaller to a certain extent.
The main process of high borosilicate heat-resistant glass is artificial blowing and semi-automatic assembly line, etc., relatively higher cost, and high borosilicate glass is more transparent than ordinary glass, feel more smooth. Even the bottle for the baby to drink milk has a high borosilicate glass material, you can imagine its safety.
