Can these hold up to hot water? I'd like to brew tea in them, and put them in the fridge while the water is still hot without the glass cracking.

I wasn't sure so ran a test for you last night. Made some tea and put it in the fridge. Didn't use stove top boiled water, but microwave boiled water. No cracking. You might want to make a bottle holder of some sort since the bottle was very hot. You should still check with manufacturer about cracking danger though. I have used a similar thickness bottle, that let's you unscrew the bottom to fill with ice, then add your tea and hot water to make instantaneous ice tea. Hope this helps.

Yes. I use them in the microwave all the time. When you heat water for tea, the outside of the glass barely gets warm.

I've had no problem. I use these everyday for tea. I am always sure to put in a spoon before I pour the hot water in.

I have never put them in the microwave. If I want the coffee hotter I just run hot water in the cup first. Yes, they are fragile but I love them and just order more if I break one.

I do use these with hot beverages - actually tea and I don't find it a problem as it doesn't get any hotter than the beverage and if you are cautious when you initially use them until you become used to the difference and use common sense, you shouldn't have a problem.

I have made chocolate shot glasses with them, using melted chocolate, so I do know that they will stand up to heat, if that was what you were wondering~ I hope that helps?

I would not recommend it if you want them to last long. My experience is when I put similar cups even on the top shelf, they end up with cracks over time.

I've put boiling water in my Nalgene bottles just after dinner, and tossed them into my sleeping bag on cold nights. Yes, they will hold up to hot water.

Hot water is fine, these are thick sturdy glass. I do hand wash the tops, easy to do and I don't want them to bounce around in the dishwasher.

I used them for cold beverages. But where they are glass I would think hot drinks would work in them as well.

I'm quite sure they are... don't think your dishwasher water will be hotter than the coffee.. ;)Maybe I should ask who the dishwasher is...lol

Honestly I don't think the heat would cause them to rupture. HHowever this is the only thing I wouldnt recommend them for. ...unless you've already iced the coffee and wanna use them to keep the coffee cool on a commute to work, etc. But these have held upto A LOT of wear and tear ....day in and day out. So I maybe surprised. Please let me know if u give this a try. :)Curious now lol

Linda, sorry I do not know...These glasses have not been put to any type of heat test. The density of the glass is greater than that of a regular glass. I trust someone will be of greater knowledge/information. I am guessing they could handle boiling water with no problem...beyond that???

While I have not used boiling water, I've poured extremely hot water straight from my percolator into the pitcher. It should hold up just fine.

No! One of your previous answers said yes but after having break right after using in the microwave I checked Teavana's website and they say no. These areally great glasses for tea or coffee. They look great and having nice and are well balanced. But don't use them in the microwave.

These get water hot, but I would NOT use them to boil water. They are really used for heating sealed meals (e.g. MREs) and possibly sealed beverages; not boiling water.

I am not sure about boiling water. They do hold up in Temps of 170 for several hours.
