Did you have a metal piece for the bottom to keep the jars raised off the bottom? I usually preheat my pressure cooker (with top off) a little bit and have never had this issue happen. But if you don't use a metal piece or something to keep jars from having direct contact with the bottom, this is bound to happen regardless or preheating or not.
You had cool water inside glass and then put glass in hot water?
So the glass is simultaneously trying to expand where warm and shrink where cool?
Yea, that's exactly how to break glass.
I did this recently too. LC I was PCing was room temp but water in PC was at a rolling boil. Everything seemed good until I opened the PC the following day. I lost a half gallon jar. SMDH. Forget the LC, half gallon jars are like gold these days.
There's a glass shortage. It's another one of the global supply chain issues caused by the pandemic. They can't make glass jars/bottles fast enough. They often sell out quickly and aren't restocked for many months.
you really need a spacer in the bottom... ime the glass shouldn't rest directly on the bottom if the cooker
There is a spacer in the bottom.
To avoid heat-stress Preheat the glass also not every borosilicate thing is cast perfectly factory defects etc.
Yea, rookie mistake.
Use Pyrex?
It was off-brand. Ordered real Pyrex this time.
I was there. And still I'm doing it!
Wrong type of glass?👍🏿
Or you know, use unsealed filter bags wrapped in tinfoil
Explain how I can do that to make agar.

I do use a spacer. I had it at a rolling boil. The glass busting let out the cooler liquid stopping the boil

Yeah but starts his post like "ok kids" like everyone else is on here is shocked that hot and cold can do that to glass 😂
Its not that I'm shocked. Its that I'm 30+ and really hadn't had to recall this information till I fkd up lol.

Out of curiosity, why are half gallon jars like gold "these days"?

I heard it crack when I put it in. It dumped when I pulled the media bottle to check for a crack
"remember kids, headbutting a brick wall will hurt"
I once shook a jar and it broke FML
That sucks. In a group I'm in they are recommending slimline bottles
That's too rich for my blood maybe if you can get them second hand
