Can they be used for making hot tea, i.e. will they crack from hot water?

I just heated a glass of water in the microwave for 1 min & 5 sec. The water got very hot, enough to make tea that was hot but not unthinkably hot, and the glass did not break. In fact, I could hold it in my hand without discomfort. I would say you are fine to heat water in it and not have an issue. Good luck.

I boiled a water filled glass in my microwave when I first bought the set. It did not crack. The glass is tempered. I have not done it at all since then so I can's say anything about repeated use like reheating a glass of tea. I use them mostly for cold drinks. I really like the way they stack, feel in my hand, and clean easily.

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

We used them for ice cream. They're thin - I wouldn't try them for anything hot as it would probably melt the plastic.

how can they be used for hot drinks but not in the microwave? It doesn't say so I wouldn't try that

Yes you can use them for hot liquids, however, I would avoid extreme temperature changes because they are glass and they will break.

I do not think so. They are heavy paper and insulated. They are good for hot coffee and tea though.

I think it be just fine to use these for hot beverages. They seem to be very durable.

I don't see why you couldn't but are you aware that a lot of teas should never be put into boiling water? A lot of teas actually are recommended to be done at lower temperatures. I'm not trying to solicit but I am part of a company that does sell loose leaf tea and there is a tea app if you have an apple or android cell phone that you can download for free. Go to your app store and look up Tealightful It has a lot of great information about all types of tea.

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 bought these as gifts, but I don't see any reason why not to be able to use them for hot liquids. I can tomatoes and jams in boiling water - why not tea?

Shouldn't be a problem but to be safe check the manufacturer's instructions. They are made to handle boiling hot liquids.

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.

I used these for iced tea and lemonade. You could put hot tea in them, but it would be difficult to drink with the straw and taking the top off would not be an option. Hope that helps.

As far as I can tell they need to be made with boiling water...never tried any other way. I've been buying them for quite some time, and we love them.

Hello, If you mean hot tea and coffee, yes they will work. Thank you for your interest.
