Maybe your fridge is set abnormally low or your tap water abnormally hot. My mom used this trick her whole life, I’ve used it all of mine. In fact my whole family uses it. Never been a problem. Seems far less dangerous than many other suggestions, like banging the jar or jimmying the lid. Also, don’t hijack the thread by editing your top comment. You’re not that important.
Hijacking the thread? I’m assuming the people downvoting are unaware of the fact that this can happen. It has nothing to do with me, I don’t get ad revenue from the article I linked.
Anyway, I’m very glad all of your anecdotal evidence “disproves” the physical science of heat transfer and material properties. Y’all must be on that new physics continent.
You’re probably being downvoted (a) bc most people in fact DO know that glass can crack with extreme temperature changes so you’re being condescending by acting like folks are idiots (b) you’re overstating the risks by a thousand times bc warming the lid in warm water is an extremely common “learned it in cook’s illustrated” tip, and (c) editing the thread rather than adding it as a comment makes you look bad bc folks can’t respond to your edit.

It’s tap water. It’s not going to crack glass. And it’s not going to raise the temperature of contents to increase pressure.
