I store lots of food in canning jars in the freezer. They should be just fine. (Note if you store liquids in them make sure you have at least 2 inches of head room or they will break.)

Ditto what bbh said. I freeze foodin them all the time, just make sure there is adequate space for expansion.

I like the wide mouth variety for freezing

My empty jars are stored in an unheated shed same as mom, grandma, and great grandma did. Never had any break. Just don't take a frozen jar and put it in hot water, or vice versa. Sudden temperature changes can break glass.

We store alot of jars in MILs basement. Oh yea it gets cold in there. But none have cracked.

I do not put glass in my freezer. I did it before and had some breaks so now I shy clear of it. Just me.


and edited to say:

I bought a couple of boxes of new jars this year, and was surprised to see that they now ship with the rings and lids on top of the jars, as opposed to separate like back when I had bought jars in the past. It gets really cold here, and I'm sure they don't heat the trucks they ship that kind of thing on, so they survive into the -40s around here with no problems--with the lids on. I've left boxes of jars (without lids on) out in my unheated garage through all 4 seasons, so they've baked and frozen alternately--sometimes in the same week around here!

Mason jars are built tough to withstand the high heat of water bath and pressure canning, and also freezer temps, so I can't see a problem with where you store them

Big Brown House may just know what he is talking about. Water on average expands10% by volume. A quart jar will expand from 32 ounces to 35 ounces thus breaking or numbing the jar. Leaving a 10% head space is good sense but will not always work as water can also freeze in thermocline plugs long before the whole container will freeze and can also break a jar even being half full.
