How to judge the material of the glass is high borosilicate?

There are two common materials for glass cups, one is ordinary glass and the other is high borosilicate glass. These two materials are also often used in our lives. As we all know, in terms of performance, high borosilicate glass material is better than ordinary glass material. So how should I judge whether the purchased glass cup is high borosilicate glass or ordinary glass?

Ordinary glass is also called soda lime glass, and there is a big gap between soda lime glass and high borosilicate glass. The advantages and disadvantages of the glass water cup can be clearly seen from the comparison of these two materials. Soda-lime glass cups are relatively inflexible, which is obvious to all. It is specifically manifested in that it is easy to burst when exposed to extreme ice or extreme heat, and the soda-lime glass cup will appear a little rough.

High borosilicate glass cups will not have this phenomenon. Even in extremely cold and extremely hot conditions, high borosilicate glass cups can withstand this temperature difference well, and the transparency of high borosilicate glass is also Better than soda lime glass

Therefore, to judge whether the glass water cup is made of high borosilicate glass, we only need to introduce ice water or boiling water into the cup, or pour the two alternately, and then observe the situation of the cup. If there is no reaction, it can be concluded as high borosilicate glass. Of course, you can also observe other things, such as the clarity, refinement, and roughness of the cup.
