Heat resistant glass can withstand sudden changes in temperature, why do some ruptures occur? Huang Dapeng explained that if glassware is subjected to vibration during normal use, tiny cracks that cannot be seen by the naked eye may occur inside, affecting the stability of the structure. When subjected to external forces, it may break. Therefore, in daily use, in order to prevent rupture and other problems, the following precautions should be taken:

1. When used in the freezer compartment of the refrigerator, the storage volume should not exceed two-thirds of the container; Glassware in a closed or semi closed state shall be prevented from containing liquid such as juice, broth, milk, Congee, etc. Because the volume of frozen food expands and increases, it can also cause product damage.

   
   

When heating in the microwave, be sure to open the lid. Although the box cover is made of PP material (cold/heat resistant temperature B20 ℃ -120 ℃) and the sealing strip is a silicone pad (cold/heat resistant temperature B40 ℃ -200 ℃), it is affected by thermal expansion and contraction, which may cause the box cover to be unable to open or deform, affecting the product's sealing performance.

3. Use steaming pots with caution, such as steaming fish, steaming egg custard, etc. The pressure of the steaming pot can easily react with the heat-resistant glass, causing slight cracks in the glassware.

4. Avoid using steel wire balls during cleaning to prevent scratches. Avoid using hard objects such as steel spoons to strike and prevent damage.
