What does the quality of glass depend on

The key to the quality of glassware is the material. According to different materials, kitchen glassware can be divided into ordinary glass, tempered glass and heat-resistant glass three types. Ordinary glass has a fragile weakness, and tempered glass is more used in car glass, bath partition, telephone booth and other fields, but when the temperature of the surrounding environment changes suddenly, it is likely to break, so it is not suitable for use in the kitchen that often needs to be heated. Compared with tempered glass, heat-resistant glass containers, although slightly weaker impact resistance, have superior heat resistance, and will not release harmful substances, and are safer and more secure to use.
