Which type of glass is superior: sodium calcium glass or high borosilicate glass?

Which type of glass is superior: sodium-calcium glass or high-borosilicate glass? In comparison, high-borosilicate glass comes out on top. Sodium-calcium glass is a common variety characterized by its thick walls and base, primarily composed of silicon, sodium, and calcium. While it offers good chemical stability, it lacks heat resistance and is not ideal for boiling liquids, making it suitable only for cold beverages or storage. So, what are the advantages of high-borosilicate glass? The details are provided below for your review.

1. The composition of high borosilicate glass is mainly silicon and boron. High borosilicate pipes and bars are a kind of special glass material with low expansion rate and high temperature resistance, with a softening point of 820℃, high thermal stability, resistance to cold and hot temperature difference of 150℃, high light transmittance, high chemical stability, high strength and high hardness.

2. High borosilicate glass can not only be made very thin and translucent, but also the body and bottom of the cup are formed in one piece, and there is no risk of cracking. It can be used as a heat-resistant glass water cup, glass tea set, etc.

3. High borosilicate glasses do not contain lead and other harmful substances. Even after being placed in water, they will not precipitate harmful substances to the human body. They are non-toxic and odorless. They are more wear-resistant and corrosion-resistant, not easy to age, easy to clean, and safe to drink.

4. When choosing a high-borosilicate glass, you should choose a high-borosilicate glass from a regular manufacturer, so that the quality of the glass will be guaranteed. At the same time, if there is a baby at home, you can also choose a high-borosilicate glass for the baby bottle.
