I bought one for my husband. He had an old Tupperware one that he would use in the microwave, so I bought him this one. So far, it is doing fine. Uses it for hot and cold drinks. Haven't had it too long, but it is holding up well. Hope this helps a little.

To be honest, I would not put it in the microwave. I would heat the contents first and then put them in the tervis tumbler. I have never done this with mine and I think that it would damage the cup. Although there is a warranty with them, this might void it.

I believe they say not to use in the microwave. I'm not sure however as I no longer use a microwave (due to the research I found) and don't pay as much attention.

You can use them over and over again... You just need to watch out for the time you put them in the microwave, if you are using them warm... I put mine for too long and one actually explodes :-(... They are a great product, just follow the instructions!

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.

Because it is not clearly marked, I wouldn't assume that they are microwave safe. My Pyrex bowls are all marked safe for microwave, for example. They are rather thin, so on the plus side each piece is lightweight, but not as durable as something heavier. I guess that's the trade off.

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.

I went to the website for Chef's Planet and all it says is that it is dishwasher safe. Nowhere does it mention the glass being microwave safe. However, it is a pyrex type glass...

I would suggest that it may not be safe because as Stavros mentioned there may be metallic substances in the glaze or the ceramic. And neither have I tried it in a microwave - like the others. I only use it with hot water from the kettle and I hand wash it.

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.

They are microwave oven safe, but haven't used them in a conventional oven. I don't believe it says that they are on the advertising.

No, not in the year we've owned ours. We put food in them, freeze them (lids on), then put them straight in the microwave (lids off). We are not particularly gentle with them. However, as a glass artist, I'm going to tell you a secret: ANY glass CAN explode. It is an inherent danger of all glass. You get a particular kind of bubble when making it, or a scratch/chip from hard use, and then even a minor temperature differential can cause the glass to shatter. Manufactured glass almost never gets those bubbles. Most likely, that reviewer or her MIL (or someone at the store) had dropped the container and it had chipped or cracked, possibly without them noticing. This can happen to any glass, as I said. But it is rare. Look at all the glass in your kitchen, and in your friends' kitchens, and ask yourself how many times something has exploded, and that should give you an idea. Having a glass item explode, while very scary, is not as dangerous as it sounds. Other than fairly minor scratches/puncture wounds, the only real danger is your eyes. I wear goggles in the shop, and I've had several things explode. Outside the shop, though, I don't risk my eyes. And you shouldn't, either. For safety, you should always very carefully check any glass item after dropping it and, if it is chipped or cracked, even if it's very minor, toss it in the recycling bin. I know most people don't do this, and I know many times it doesn't explode even then. But there is that one time, when the crack or chip is in the right place, and the temperature differential is in the right place, where it will. Is it worth the risk to your eyes?

I just read that they are not recommended for use in the microwave. Oops. :P

Absolutely not microwave safe. They are made of metal and would definitely cause some sparks! They are super durable, dishwasher safe and all around awesome. I get many compliments on these!!

I'm sorry I don't know the answer to that. I haven't used them in the microwave. I had the WS nesting bowls too, and found that over time, microwaving was not kind to them. I doubt it was the microwave itself, but rather the very hot contents. I'd ask Oggi.

These are tempered in that they can be used in the oven and microwave. I would be hesitant to use any glass in a child's lunch, as children tend to break things. I would use them in my lunch container, mine gets less rough treatment!

Not sure, but I think they'd be okay in the dishwasher but not in the microwave. They are just plastic plates and might melt. There are so many in the package that I never needed to wash and re-use any of them. I have put similar items in the dishwasher and they came out okay (as long as not on super hot cycle). I never put one in the microwave, but other similar plastic things have warped or melted. Might be okay for 30 seconds.

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??
