I want to freeze water in these, will they hold up until the water freezes or will they saturate before then?

I said no at first--but saw other people saying "most likely" so I filled one up with water and left it over night, on the counter - IT WORKS! I guess this means soup can also go in, just not hot as I am sure that would melt the wax coating.

I use these to do the final freeze on ice cream which is thicker that water. I also use them to freeze ice cream liquid mix which is about like milk and they do not saturate before it freezes. They are quite sturdy - I'd say give it a shot and see what happens - allow a little room for expansion.

Have not attempted this, but I feel confident that they would hold up for a single use if they went immediately into the freezer. I am equally confident that they would NOT hold up for more than a single use and/or if the water were significantly hot when put into the container. Hope that helps.

You should be fine, they are wax coated, I use mine for homemade ice cream haven't had a problem with them.

I've frozen very liquidy ice cream before with no problem. The cartons seem to have a light wax coating on the outside that should protect the paper from saturation.

I have never tried to freeze water in them so I don't really know. they are wonderful for icecream though.

Yes, they can. If you intent to keep them permanently in your freezer, make sure that automatic defrosting system is working well.

I have not tried to put them in the freezer. I am writing this to you as I sit next to the pile of used ones that need to be heated again to make them liquid, they become solid after use. That pile has been there for several weeks. Really not worth the money. I would not buy these again, they are a total pain. If after you heat them if there is even one crystal left, this can be very hard to see, they will just reheat when you take them out of the hot water and you are stuck heating them again to reset. They do not stay warm for nearly long enough to make them worth it. I would strongly urge you to skip these and go with an old fashioned water bottle. Sometimes an oldie is a goodie.

These mugs can stay in the freezer until you are ready to use them. I put mine in the freezer and take them out as I need one and then put it right back in. They are great.

put them into water then put them into the freezer for about an hour and you will have frosted glasses

I have had no issue using them in the freezer for short periods of time. The seal is pretty tight. Long term like with any type container frost builds up.

I make sure that the 2 halves are together and fill through the hole at the top. I leave about a 1/2 inch free at the top for expansion. I let them freeze for approx. 4-6 hours.

They don't require freezing...they're dry. I'd be afraid of them cracking into pieces. I store the unused in a large Ziploc. They don't go bad. Place 1 flat in lukewarm water for 10-15 seconds and as you arrange your filling for rolling, it gets more and more pliable. They're quite lovely.

They will turn solid when frozen and slowly thaw. If you keep them in a good insulated cooler they should stay frozen for the flight

I think they would hold a cup of water. They work very well. They are a little on the thin side but they do hold up overnight.

I don't think they will break if frozen because they seem to be substantial and pliable enough to withstand freeze, but I have not tested them. I have been very pleased with how well they are holding up after several dishwasher cycles. Still look and feel brand new.

Yes, I use them all the time in the freezer. Two things to be careful with, do not fill all the way to the top because any water in the food or liquid will expand while freezing, and do not put into hot water right away, let it thaw. Glass breaks when it goes through sudden temperature change. I have not had a single problem. To me the extra steps with glass is worth it, because it doesn't absorb odors and it doesn't permeate into the food like plastic.

Absolutely, I have filled mine about have way and frozen it then filled up with water, cool water for a while.

Never tried freezing anything in them but a quick dip in hot water might be enough to release the ice without bending the cup... Good luck

Each square is filled with water(?) and when you put them in the freezer you have lots of little ice cubes which will melt, but they won't turn to liquid and spoil anything. You will just have liquid again in the little squares. If you put them in an ice chest with the lid closed, they will keep food cold for a day is my guess, but I think it would depend on how much you open the chest and how hot it is. I wouldn't expect them to stay frozen for more than a day.

We have used 100's of these and they hold up well in the deep freeze. They stayed sealed and do not crack.

I have not tried to freeze them. And I don't think it would work very well. If the expanding liquid didn't break them, the extreme cold would probably make them more prone to crack
