How can I open glass airtight jar, when it's plastic lid stuck because of air pressure?

Question

I have a glass jar(airtight). To open it I don't need to twist. All I need to do is to unlock from 4 sides and pull it up.

Last week I put this jar in microwave with its lid(plastic) on. Now this lid is stuck in the jar because of pressures.
How can I open it without any damage?

Answer

Try shirt in hand when twisting I assume your talking like an air tight mason jar that's what I always did when I couldn't open my papaws air tight garden mason jars. The shirt and making sure the jar is level and sitting it on the table helped me get it open.

Answer

Heat it until the pressure inside goes up. The lid will open easily. How you hold the hot jar is up to you.
