We are often asked if the Mepal Cirqula multi bowl's lid is microwave safe. It's an obvious question since the bowl itself can be used in the microwave. Unfortunately, the lid cannot.

Why can't the Cirqula lid be put in the microwave?

The multi bowl's lid is not suitable for the microwave because of the material it is made from. Temperature differences in a microwave oven can cause this material to expand or shrink, which means the lid may not form a perfect seal afterwards.
