When at slightly chilled temperatures (Like a winter's day), will they crack if you pour boiling water into them?

I use them daily and never worry about the temperature of the glass before I pour boiling water in it. I am very careful though when I wash my wine glasses because I know if the water is a bit too hot they will crack. I can't say that if you have them in the freezer before filling them with boiling water, that they won't crack, but under normal room temperature ranges or even slightly below, I would feel very comfortable. They are extremely sturdy.

I have only used mine for iced drinks. I would think it would be OK to pour boiling water in them on a chilly day.

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???

No. My pitcher was room temp and I poured boiling water in it for tea and the whole bottom cracked. Another one bites the dust.

I have not tried to freeze them. And I don't think it would work very well. If the expanding liquid didn't break them, the extreme cold would probably make them more prone to crack

I see no reason why not, I have it in 115 degree temps right now ...the sides are very thick, I don't believe it would crack

I don't think you can. I used it to brew kombucha. If you would put it into boiling water it may crack. I'm sorry that I'm not sure

I cannot answer about the boiling water, I can tell you that they are not the same thickness as a regular canning jar. They appear to be somewhat thinner.

I did this about five times until it cracked and I have terrible burns. The pitcher was at room temp on a warm day and the water was slightly off boil. BEWARE!!!

No, not really. If you let them melt in your mouth a little then they break a part fairly easy!

Whether heat would damage them or not, I don't know. However, they would not turn hot tea cold; we have found that they keep cold things cold but do not work well at chilling a beverage.

I don't know the answer to that, but I can tell you that I use them in the hood range above my stove. Boiling water for a long time tends to temporarily short them. I'd say you'll need to have a good seal around them. I believe the issue is moisture and not heat.

Yes, ready to go! If you decide to use them again, soap and water will clean them and you can boil them too. Once you see them starting to crack they're no good.

i boiled mine for 20 minutes to seal them. they did not crack, but they were room temperature when i put them in.....

I think they can withstand heat; just not from cold to hot. I think most glass is like that.

The plastic is tough enough that I am sure you could put them in a pot of simmering water. I just have never done it that way and thus do not know how long you would want to leave them in. I would not boil them though.

Yes, I freeze food for my kids in them. None of mine have cracked. The kids are hard to take off immediately out of the freezer. But after a couple of minutes out of the freezer its fine.

Yes. They're made of silicon, so you won't get a drink hot enough to melt them. They're not so thick that you won't be able to feel the liquid coming up, but not so thin that they're flimsy, either.
