Is this mug microwave safe?

Yes, I've microwaved milk in one (though I haven't tried really high temps).

I don't know if it says that it is, but I have microwaved it on high for 2 minutes - not more.

Yes! Microwave safe..... But do be very careful when washing... If the glass slips off your hand.... Say good bye!

We have had no problems with the mug in the microwave. Because of the large mouth it doesn't hold the heat as well as I thought it should.

We microwave tea in ours all the time. But don't stir anything in the glass or the inner wall will break. See reviews for breakage frequency. If they break within 30 days amazon replaces.

I don't see why you couldn't microwave in it. I don't see anything that says not too and it's similar to other mugs I microwave in.

I do not have my packaging anymore so I don't know if it says it on there, but it does not say if it is microwave safe or not. Honestly I would assume it would not be microwave safe. All of my other sippy cups are not so I think this wouldn't either. About the leak proof. Well at first yes I could say it was leak proof. But after a few weeks my son learned about banging his sippy cup on the highchair. Since the very first time he banged it on the tray it has leaked. Since then I have purchased other sippy cups and have not used these sippy cups since.

Yes, the glass is microwave safe. However, the lid tends to get warped over time.

No! You will ruin your mug! Do not put it in the microwave or the dishwasher.

I've owned two of these mugs for several years. There are no markings on them to specify the nature of the glass. However, I use it in the microwave to make boiling water for tea without problems, or pour boiling water into into it. I replaced my first one because I accidentally knocked a small chip off the lip; the glass did not shatter so it is probably tempered at the very least.

On the bottom of the mug it states, Do not place in microwave, and handwash only. If I put it in the dishwasher it would be top shelf not the hottest water.

I bought that for someone else so I don't remember if it is microwave safe.

I haven't washed it in the dishwasher, but I'm pretty sure it is dishwasher safe. It's an easy to clean cup so I always handwash it. As for the microwave, no I wouldn't put it in the microwave. I re-heated coffee in this cup in the microwave, and the cup was EXTREMELY hot. Hot enough to burn and sting my fingers. Dishwasher = probably okay. Microwave = NO.

Yes, this mug is microwavable. In fact, it's one of the main reasons I bought it.

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.

As of today, Oct 16, 2014, the tag on the cup I just bought at BB&B; (where turnover would be high) says it is microwave safe. However, this morning when I checked the website, it only listed dishwasher safe. I think they've had too many complaints of microwave problems.

Yes. I use the "warm up" function to keep coffee stable temperature. The glass is microwave safe according to the included product documentation.

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

I should not even try it. Metals in microwave are dangerous. I heat the milk in a regular cup and then pour on the stainless steel cup
