How to Verify Whether the Glass Cup is High Borosilicate Heat-Resistant Glass
High Borosilicate Heat-Resistant Glass is a type of glass that contains boron trioxide which allows for a very low coefficient of thermal expansion. This means it will not crack under extreme temperature changes like regular glass. Its durability and thermal resistance make it particularly suited for applications that involve rapid temperature changes or where high heat resistance is required, such as in laboratory glassware, cookware, and even in some consumer glass products like teapots and coffee cups.
