Can A Universal Glass Lid Break From The Heat?

A universal glass lid can break for thermal shock when it is heated. If the glass material gets different temperatures for different surfaces, the thermal inflation causes stress from one side to the other of the glass material.

When the stress overtakes the yield stability of the glass material, it leads to cracks. As it’s fragile, slowly it shatters into pieces from its first crack.

Compressive stresses may be the cause of glass breakage. When the strengthened piece of glass heats up over the tempering point, it will break. The main point is that any glass material will break when the temperature reaches above its maximum temperature.

Different types of glass including Borosilicate glassware, Tempered glass, toughened glass, and bulletproof glass have different temperatures to break the glass.

Lid Quality

Slow Cooker lids are made with formal glass. Regular glass can be easily broken down by small mishandling. So, you should use a high-end material based lid such as Pyrex. Because it assures higher quality along with lower possibilities of breakage.


If you don’t want to use a regular glass lid or even pyrex material, you can try plastic lids. Because they have lower risk of breaking or shattering.

Similarly, thermal glass is made with a mixture of two various glass kinds. So, it is unable to mix with different glass kind proportions. As a result, the change can cause uneven construction. And also increase the chance of breakage.


To reduce the shattering of the slow cooker lid, you must be sure that the lid doesn’t clamp down. Because clamping is the main reason for the slow cooker into pressure cooker transformation. As a pressure cooker develops heavy pressure. And the slow cooker can’t handle such pressure. So, be careful.
