Why did the glass suddenly explode after pouring boiling water?（one）

I saw a short video on the Internet today, a live broadcast of selling glass drinking glasses online.When demonstrating the quality of the water glass, it suddenly exploded after pouring boiling water into the glass.Although the scene was very embarrassing, including the comment area, there was a voice of questioning the quality of the water glass, but it is worth the fact that the boiling water splashed by the explosion and the glass ballast did not hurt people.This happened when the other host just introduced that glass can withstand high temperatures, and the host was also confused.Does this happen because of improper operation or poor quality of the water glass?

The glass cup is relatively brittle and fragile due to the material, which is known to everyone, but whether the glass is resistant to high temperature is not fully understood and also wanted to know.

At present, the editor of glass cups on the market has mentioned in the previous article that they are generally made of soda-lime glass and high borosilicate glass.Soda lime glass is easier to mold, but the glass texture is not tight enough to process very fine glass products, especially optical products.Usually we see soda lime glass products such as seasoning jars, airtight jars and water cups.Soda lime glass itself has poor high temperature resistance and poor temperature resistance. How to identify what is soda lime glass?

This point is also described in detail in the previous article by the editor. Friends who need to know can read the previous article by the editor.When using a soda-lime glass water cup to drink water, control the water cup below 70°C so that it will not burst suddenly.Due to the poor temperature resistance of soda lime glass, if it is stored in the refrigerator for a long time and the temperature of the water cup is below zero, it may explode if the hot water arrives immediately.You should have learned this kind of reaction in the physical chemistry class of junior high school.When using soda lime glass, try to control the temperature of the water cup and the temperature of the solution within 40 degrees, so that it will be safer when you use it.

The above are the characteristics of soda lime glass, so what are the characteristics of high borosilicate glass? We will share with you in the next article.
