Can these hold boiling (212 degrees F) water without damage? And will the heat transfer to the outside and hurt your fingers or is it insulated?

I would not even try to put biking water in these as they are wine glasses. They are good quality plastic wine glasses. No where does it say they are insulated.

The mug will hold up to heat and the handle remains cool. However if your knuckles touch the outside while holding, it'll burn. I tested with spiced cider.

it's not well insulated. the digital read out tells you the temperature. However, the water tastes great when boiled in it, the temperature differential for each type of tea works great. My mom says that she's never had such a great tasting cup of green tea, when prepared at the proper temperature. And it's easy to re-heat the water and then turn off the heat. If you are looking for something really insulated, you need a different product.

I have made tea in them- but I normally let the water cool for about 4-5 minutes before I pour into the pitchers. They are very think glass and very sturdy, they may be able to handle boiling water, but I haven't risked it.

Not recommended for exposure to hot liquids as the base material would likely allow penetration through to fingers and hands. The gloves are highly resistant to hot objects and steam (up to 640 degrees F), ideal for handling pots, pans, broilers out of the oven, but if resistance to hot liquids is a requirement, best to get gloves specifically designed for that environment -- these gloves are not!

It gets warm but not hot. I often pour boiling water in mine just as I'm walking out the door and never have a problem with it getting too hot to hold. Drink yes; hold no.

Yes. The handle does get hot, and you will need a glove or towel. The beauty of these authentic pans is that they get hot very fast...and hence are great for bringing liquids to a boil. The surface discourages sticking, too!

They're absolutely not good for anything below +10F. Your fingers will freeze in a hurry, and that's even if you're wearing an inner glove liner.

It can hold hot or cold, but it is not insulated, so it will not "keep" your drinks hot and cold.

Lukewarm won't be a problem. It is sturdy bpa free enviro plastic. I wouldn't store boiling water in there but I use very hot tap water to clean it on occasion and it's not a problem.

It should get hot because its boiling water but keep an eye on it you don't want it to get extremely hot, it may burn thru the plastic

they are metal, and as one reviewer noted, if you have an overflow due to the scoop design allowing it to stack, it can collect some hot water in there. THAT can burn you. I have never believed the handles themselves are too hot under normal situations.

I wouldn't do it. Stainless steel retains the temperature in it, and if you touched the bottle with liquid inside it at say 120 degrees, you'd burn your hand. You might try heating liquids in the bottle by placing the bottle in a pan of hot water for awhile, but be careful. I've never tried it. Hope this helps. JC

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.

A simple answer would be . . . ADEQUATELY. They definitely are not as "insulated" as a fully insulated cup, however, they do insulate better than your basic plastic or china cup. I sure hope this vague response helps.

Not really no. It's not insulated and like the other reviewer said, there is no keep warm feature. I have heated water at the middle to end of the heat spectrum. I'd say it's warm-cool within 10-20 minutes. I don't feel its a problem for me just because it heats up again just as quickly when I turn it back on. I'd say about three minutes,it's boiling again on the highest setting.

It really depends on how hot your water is. If you use boiling water (not really recommended for most teas if you don't want it bitter) then the glass will get uncomfortably hot to hold (not leave actual burns, just uncomfortable to hold). I found that the outside only remains uncomfortably hot for a short time if you use really hot water. If you plan on filling it with boiling water and then heading out the door, you might want to purchase some sort of a sleeve for it.
