Tempered glass is not heat-resistant, and household kitchen utensils should be used to distinguish materials to avoid danger.
As glassmaking processes have become more sophisticated, beautiful and durable glassware has become more widely used, especially on the dining table and into the kitchen. Heat-resistant glass is widely used in baby bottles, kitchen glass containers, and experimental flasks because of its excellent temperature-change safety characteristics.
At present, the glassware that consumers often come into contact with in home life mainly includes three types of ordinary glass, tempered glass and heat-resistant glass. Most consumers know that ordinary glass cannot be used in high-temperature heating environment, but many consumers do not understand The difference between tempered glass and heat-resistant glass is that the tempered glass container is used for cooking purposes, causing an incident of tempering glassware after a burst.
The reason why tempered glass is easy to bleed is because in the process of manufacturing, it often becomes a mixture of nickel sulfide component (NiS) that cannot be found by the naked eye. This kind of nickel sulphide will cause tempered glass to occur under the change of ambient temperature and glass. A large expansion of the match results in a self-explosive flying film phenomenon.
The heat-resistant glass suitable for kitchen use contains high temperature resistant borosilicate component, can withstand a high temperature of 400 ° C, can withstand the temperature change of quenching and rapid heating at 120 ° C, and has no self-explosion danger.
