Although Glasslock's products have some strength, its crisper boxes are made of tempered glass, but they are claimed to be tempered heat-resistant glass. Tempered glass is essentially ordinary soda-lime glass, but the mechanical strength has been improved, the impact resistance is strong, and it is not easy to break and damage, however, this kind of glass is not heat-resistant, and the heating is uneven on the same glass plane, and there is a risk of bursting in the case of high heating temperature or large temperature difference, which is not suitable for putting it in the oven, even if it needs to be put into the microwave oven, it is necessary to pay attention to limiting the use time.
