I pour cold milk into hot oatmeal to cool it quickly. Cheap glass bowls crack when I do this. Could these bowls withstand that temperature shock?

If any bowl is going to hold up to that, this will. I haven't had any problems with temperature variations with these bowls. (Unlike Anchor Hocking, a supposedly high quality tempered glass product, where I've had some experiences with shattering.)

Yes. If Duralex can't take it, I don't think you'll find any bowl that would. I use mine like that often.

I microwave my oatmeal in this bowl and then pour a little bit of milk maybe 1\4 (even less) cup from the fridge and so far it has worked out well. No problems with cracking.

This would not be a problem. These are made of tempered glass, like Pyrex, and can handle quick temperature changes, in my experience. Barring a particularly faulty bowl, this would not be an issue.

I use these bowls to heat soup and other items in the microwave, I put ice cubes in the hot soup to cool it down and have not had any issues with cracking. They get very hot and do not crack or break. They seem to be very durable.I don't think you would have any cracking issues with the cold milk.

I don't recall if I've used mine at that high of a temp. I have used them under the broiler (gas) for 10 mins or so and they were fine. They are pretty thick and heavy-gauge aluminum...not your typical cheap "big box store" specials. I've had several of those that after a few minutes at a high temp you can actually hear them "pop" when they buckle. I would think these would hold up well at high temps just like most all Calphalon does. Regardless, they have a warranty from Calphalon so if they buckle, send them back. :)

I love these Tritan bowls. They are clear, tough, look great and go through the dishwasher time after time and come out looking good. However, I don't think that these are made for hot soup temperatures. I haven't tried it however, so . . . .

Mine have held up fine through many re-heats (although mine are different than this picture, the lids are hard plastic with a rubber gasket and snap on). The glass bowl certainly is microwave safe, so if you are extra-conscious about plastic in the microwave, just take the lid off.

I have not used them in the microwave but I would think so as glass is usually tempered to withstand heat. You'd re-heat soup since they're soup bowls.

We used them for ice cream. They're thin - I wouldn't try them for anything hot as it would probably melt the plastic.

They can get hot. For example I microwaved broccoli in one of the bowls with a plate set over the top yesterday for 3 minutes and I had to usepot holders to take out out. Just a typical plate of food for a minute or two doesn't get overly hot.

No. The bowls did not break. The motor broke the first time I used it. The bowls were in the freezer for a good two weeks, they are / were undamaged.

I don't know what the manufacturer has to say about the matter, but I would not put them in the microwave. I have been putting mine in the dishwasher, and I think that was a mistake. I have broken two of them because the glass seemed to be very fragile. Make no mistake, even though I don't recommend the microwave or dishwasher, they are a great buy. The double glass keeps the coffee warm for longer than regular coffee mugs!! I was so sad when mine broke. I will say, it was the gentlest bump that broke them...even so, I will be replacing them soon. I love these glasses.

I would say no. They aren't supposed to be exposed to extreme temperature changes and it seems to me a microwave would heat them too quickly.

These are pretty heavy duty glass dishes. In a lunch box, I think they'd be safe without breaking. Also, unless the glasses are held upright at all times, I would not reccommend putting anything too liquidy such as dressing or sauces. It might seep through.

I think so. They are a very thick glass. I wouldn't think twice about putting one in the microwave.

I haven't tried it but if it was something I needed to do regularly, I would risk one bowl to find out. I really think you could but can't promise. I guess I haven't put anything super hot in them, maybe cereal and hot soup. I definitely wouldn't put anything hotter than boiling water, 212 F, though.

I would say no...I was worrying about that too when I got them as I am making fruit slushes for our Cancer Support group and freezing them. I was look for a cup that had a little give to it that wasn't brittle and these are just perfect for my needs....

I put them in the microwave quite regularly and nothing has happened to them. I like drinking warm water sometimes; so I microwave a glass of water for a minute or two. These glasses are super sturdy.
1988847
Absolutely. I use mine at 450 degrees for my French Onion Soup. They are a heavy commerical grade bowl.

I want to say 'yes' as they are not lightweight but quite 'heavy.' They are very sturdy and I have used microwave to reheat coffee in them with no issues...glass stays cool. Hope that helps!
