glass jars for the freezer?
I have some quantity of leftover chicken and beef stock and am out of 'normal' freezer containers.
How do old peanut butter or jelly or other glass containers stand up to freezing (of course allowing space for liquid expansion)?

I have frozen my stocks in mason jars for years. Only a couple have cracked - before I learned that the fill level must be a minimum of one inch below the shoulder of the jar. Also, they sell plastic lids for mason jars - I use those and love them.
Use the same lids and jars to store whole grains in the freezer.

I use mason jars for freezing all my liquids. Plastic container have always squeaked me out, the way the stain and hold onto oil no matter how you wash them. But I am weirdo.

I wouldn't do it, unless the glass containers are specifically made for freezing. I make a lot of bone broths and soups in the winter. A process that takes 3 days to do right. In the past year I've had 5 large mason jars crack on me in the freezer. The first time, I guess I overfilled, so the second time I left a very large (or so I thought) space for expansion, and left them to freeze without lids, and chilled them first in the fridge, but they STILL ended up breaking! I like using glass, as opposed to plastic, but this is a huge pain in the butt. After all the time I put into making these soups, and then they were either ruined or had to be very, VERY carefully salvaged. No one wants to eat glass shards. I probably should have thrown it all in the trash, but I couldn't bear it.
I'm wondering if maybe the slightly smaller mouths of these jars may have forced the pressure of the expanding liquid to push outward as well as upward. But honestly I don't care to test this again. I'm over it. I'm never freezing in random glass containers ever again.

Well, I've always used spaghetti sauce jars before, too, but this time one of them didn't work! I had lots of leftover homemade pasta sauce. Got out my empty pasta jars, filled two of them, and stuck them in the freezer last week. Went to get them out this morning and one of the jars was cracked/broken all the way around in several places. The second jar was fine. I filled them both the same (probably two full as I now read this thread) and let them cool off before freezing. This is the first time I've had one break. I think I'll probably do it again, but this time I will only fill them 3/4 full and will not tighten the lid until it has frozen. Thanks for the tips!

i have used mason jars in the freezer usually with no problem. Occasionally upon thawing they will crack, not sure why. Love to freeze home made soup this way. I have thawed them in the microwave on the defrost level, again with no problem, but i let the jar rest for a few minutes between zaps until it is thawed enough to pour the contents out.

Do you have zip lock bags? I'd do that before glass, but admit I've never attempted glass.
