Are these mugs labeled "Microwave safe"? Is anyone using them in the microwave (ie: to heat up a coffee?) TIA

No there is nothing stated on them about being microwave safe. Sorry I only use mine for cold stuff. Probably not a good idea to heat any plastics these days. It doesn't even say dishwasher safe??

I used my smaller ones and had hot coffee in them. Wouldn't put in the dishwasher but don't a lot of things anyway. Just got them so haven't used them yet.

Nowhere on bowls or packaging does it state "Microwave Safe". That said, I've had mine for several months and use them frequently in the microwave. Never any problem.

Although the package indicates these cups are not intended for use in a microwave, I have been microwave heating and reheating my milk in them for years. They hold up well for the few minutes they are heating and do not melt or spark.

I'd be a little afraid to put them in microwave any longer than 1 minute. Afraid they may crack. I mainly use them with my Keurig.

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.

Not quite sure how to answer this. They are not insulated. They seem to me to be pretty much like ordinary coffee/tea mugs, though with a slightly larger capacity.

I've used them in the microwave without any trouble. But I haven't tried them in the microwave for more than a minute or two. I can't imagine they aren't microwave safe.

I can say that I've used them for hot tea (out of the kettle) and frozen them for frosty mugs in the freezer, but never microwaved them. My guess is they'd be ok, as the water for tea was 200 degrees, but I have never microwaved them. I still have the set with nothing having happened to them. Sorry I couldn't help more.

The cups are pure plastic construction, hard plastic cover and inner liner, foam insulation between the cover and liner, so I would assume that they are microwaveable. However the mugs keep everything so cold and so hot for so long,, put in in hot and it will likely stay that way... On a fishing trip a while back, I filled one of these badboys up with Bailys/Coffee, took it out with me into the 30deg+wind-weather, and it kept the coffee warm all the way to the end of the cup. It didn't keep my hands warm 'cause the cup is insulated, but my belly likey...

Yes they are microwave safe. I've used them for desserts and hot/cold savory foods...

According to the Signature USA website <http://www.signaturetumblers.com/CLEAR/Clear_Regular_Coffee_Tumbler.html>, they are microwave-safe.

sorry it has taken me this long to get back to you. i think it is luke warm to warm. my coffee is hot. i would also like to tell you that i was going through some old papers and i found the papers that came with the cups. you can put them in the microwave up to 2 mins. you can also put it in the dishwasher on the top rack only and only on normal cycle with normal heat dry. i still wash mine by hand. ever since i bought these i have loved them. i haven't look for any other ones. i hope this helps.

Yes, they are microwave safe. The lid also fits pretty tight so it doesn't spill when tossed around on the go.

Actually, we gave those dishes to our granddaughter. I believe they aare supposed to be safe in the microwave, but I have no idea if they get hot in the mw. They are really pretty, and we've not heard any complaints from her!

They are not designed to withstand the "heat" of a microwave. I use glassware in the microwave.

Yes, but I recommend heating the water inside the mug. I've cracked several by pouring very hot water in them or by washing with cool water when still very warm. I never had one break when heating water in a microwave oven, even to the boiling point (by accident).

I use mine in the microwave a lot. I can't remember if the label said they were, I know they are dishwasher safe.
