Will hot water in a glass fry? The crystal double-layer glass keeps you safe!
Some glasses will explode when poured with hot water, which can easily burn family members. What is the reason? What kind of glass is safe?
First of all, there are two reasons why a glass of hot water will fry，glass cookware .
1. Glass material problem
Ordinary glasses are made of soda-lime glass. In addition to the main component of silica, there are more calcium oxide and sodium oxide. The sodium oxide in it increases the thermal expansion coefficient of the glass while also reducing the heat of the glass. Due to its stability, chemical stability and mechanical strength, soda-lime glass glasses can only hold liquids below 70°C, and the manufacturer will advise customers not to hold warm water above 60°C in the instructions.
2, glass workmanship issues
In addition to the material problem, the manufacturing process and quality of the glass are also factors that affect whether the glass will explode when it is filled with hot water. In terms of thickness, the thickness of the glass cup is too large, and the thickness is uneven, which will reduce the quality of the glass cup. In addition, due to the accuracy of the grinding tools, there will be burrs and blisters on the edges of inferior glasses. Similarly, when the raw materials are impure and the glass contains impurities, although it is difficult to see with the naked eye, there is also a risk of "self-explosion" upon collision and sudden temperature changes.
So, what kind of glass is safer for hot water?
If you want to hold hot water above 100°C, you need a glass made of borosilicate glass. Gaopeng silica glass has a high thermal conductivity and a low thermal expansion coefficient. The glass cups made can withstand high temperatures above 200°C. The safest thing is the double-layer glass made of Gaopeng silica glass. It can not only hold boiling hot water, but because it is double-layered, it also has a thermal insulation function. It is not necessary when holding the glass. Hot.
Therefore, to prevent the glass from exploding, you must look for the material of the glass when purchasing the glass. It is safer to
