Can the glass be boiling water?

In life, glass is the same utensils that people often use. For example, it must not be missing when drinking water. So, do you know that the glass can be boiled with water? Let’s take a look at it together!

1. Can the glass be boiled with water?

Yes, but if it is heated in inside and outside, it will be installed, otherwise there is a risk of rupture.

The glass is not a hot conductor. It encounters the local heat expansion of the hot water, and the part of the water without water is cold. The cold glass cannot withstand the expansion of the high temperature of the high temperature at the moment of high temperature, which will cause the cup to crack. Suddenly cold and heat causes inconsistency and contraction of the outer wall of the glass. Ordinary glass should be used to pour hot water with warm water or hot water as much as possible.

2. How to open water with a glass

1. Don’t pretend to be hot water directly

Although the glass can be equipped with hot water, it is best not to put the hot water just boiled, otherwise it will cause the glass to burst. Due to the slightly worse thermal conductivity of this material cup, after boiling water, it will cause uneven heating inside and outside, and there will be pressure outside. When the pressure of the cup is greater than the cup, the cup will burst. You can pour the appropriate amount of hot water first, and then shake the cup to keep the cup preheated in advance, and then add boiling water.

2. Use a thin glass of the cup wall

The thermal conductivity of this material cup is slightly worse. The use of a cup with a thin cup wall can reduce the heat transfer time. The cup can be quickly heated and balanced. The cup with a thick cup has a long heat conducting time. After the water is installed with boiling water, it is very easy to have a very different pressure in the glass inside and outside, so it is easy to burst.

3. Use heat -resistant glass

The glass with good heat resistance can withstand very hot and cold changes, which is more suitable for blooming water.
