Glass lids on cookware are just another form of planned obsolescence, aren't they
@xahteiwi I've got some that must be getting 15+ years or more, so I don't think so ...?
@larsmb Have you never dropped it?
@xahteiwi Apparently not.

@xahteiwi But the glass lids for my bowls have silicon seals.

Those need replacing because that does age, and also sometimes irreversibly absorbs horrible smells and thus flavors.
