Can I use these to microwave?

Direct from corning - you have to leave a sufficiently large gap for steam to easily escape or they WILL warp. I ran into this when leaving a small gap to keep the lid from popping off, and had two warp on me.They did end replacements though.

I just discovered that the lids for the Corningware® Colours™ Pop-Ins® 20 Ounce Mug w/ Lid fits these 2 cup round Pyrex. That lid has a vent. Works great. But either way, works good in the microwave. Being glass, they do get hotter than plastic, which is good for speed, bad for fingers.

Well if you do canning you know these are boiled at high temperatures to preserve food, and I've heated up foods in the microwave in the past, I wouldn't try cooking with them in the microwave but do believe them to be safe for reheating foods.... Just keep in mind it is thin glass

I think so. See post below. You can also heat them in the microwave and put them in a basket of rolls to keep them warm.

Not a good idea. They do not say "oven safe" on them. I have used them in the microwave, but they get VERY hot so I stopped doing that.

I've never tried that, but I'm leery at the prospect. I think they are meant to be used in the microwave, and could melt on a grill, but that's just my thoughts.

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

I am not sure but they would get very hot and I wouldn't chance it. Maybe go directly to their website for confirmation? They do heat up in the microwave.

No. It's not stated anywhere that they're microwave-safe, so I would definitely not try it.

I have not tried to microwave them to date. You could prob do it for a few seconds as I often will microwave my butter container to melt it & that is plastic as well. Good luck!

No they are not microwave safe and they are not labeled microwave safe. In general heating plastic releases carcinogens. Microwaving with a glass pyrex measuring cup and pouring in the contents does the job well.

Yes they are microwave safe. Don't try to cook in them but fine for quick heating.

Yes - I microwave mine all the time but do not put them in the oven they will melt.. Though I called customer service when it melted in the oven and they sent me a replacement

I'm sorry, I haven't used them in the microwave. I tend to use glass in the microwave.They are holding up very nice though in the dishwasher.

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.

Yes, they are microwaveable. I have not had them ever get hot, except where the food itself heats the plate.

Don't know. Never used them for anything other than the oven, which is what they are intended for. I have never heard of them being used in the microwave.
