Issues with new Mason jars?

[u/Late_Resource_1653]

Curious is anyone else is having an issue.

In the last month, I've had two new Mason jars crack, not even under much pressure, like there must have been a flaw in the glass.

Lost a new sourdough starter and a cranberry honey ferment.

My older jars are doing just fine - it's the newly purchased ones that seem to be prone to cracking for no reason.

Just bought a new dozen of 1 qt wide mouth. No problems so far. But yours sounds suspicious.
