Can these mugs handle boiling tea water without breaking? Are they made of the same glass as regular Ball Brand canning jars?

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.

NO... If you look real good at the picture, I'll see at the bottom, it says " NOT FOR HOT PRODUCTS '' means for cold drinks only.

Can't say for sure that they are made from the same glass or not BUT I've used them for years for hot tea, hot coffee and hot soup. Have put them in the micro wave and never had a problem. "Those years" meaning 45 at least. Now days, nothing is made as well as years ago. I would say just always be careful....NEVER go from refrig to supper hot or the reverse SUDDENLY. Hope that helps a bit. Ever googled the Ball company to contact them and ask the same question.

They say no hot liquids on them, which was a disappointment for me, but I haven't tested whether or not they can handle it.

Well, I put sand in the bottom, and stick a small taper candle in it, I can take it outside to memorials or camping and the wind won't blow the candle out. Then there is the neat handle to keep my hand cool. I never drank tea out of one, but the glass can take heat. They are not Ball jars, and they are small, but they are like Ball jars just smaller and with a handle. The top has threads for a lid if you want to make jam, oh what a good idea... Enjoy the jars!

I have looked and looked for a glass pitcher that will withstand boiling water, but have found very few that do. This particular pitcher is well made, but I've never attempted to put billing water in it. I use it for iced tea. I make the tea in a separate kettle and allow it to cool a bit before I pour it into the pitcher. Also, I put hot water from the tap in the pitcher before I pour the tea into it in order to help warm up the glass. As I understand it, the reason many glass pitchers crack from boiling water is because of the temperature difference between the glass and the water...so, I always warm up the pitcher a bit first.

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.

Not sure what you mean. I use a tea mug warmer at work. Is that the same thing? The teapot and cup are make of ceramic and will be able to withstand heat, except for an open flame. My granddaughter loved this present.

I haven't personally used them for hot beverages, but if you're looking for an alternative to plastic, I know that glass mugs designed specifically for hot beverages are available. I'll brew a pot, and pour it in the glass and confirm whether or not it can withstand high temps. Great question.

glass but I've never had a problem with them breaking. or maybe you just wanted to make sure it was BPA free. i love it and mix a little with lemon in my ice water and it tastes like weak iced tea. very yummy!

They are pretty much ceramic. I love them because they hold more tea for me and sometimes I put soup in them. I have not had any trouble keeping things hot. But, honestly, depending on the air temperature, they might not keep it really hot for 20 minutes.

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 do not know what the manufacturer says, but I have boiled water in a mug. The mug didn't break, and the handle stayed cool.

Absolutely not. It will break. This is will be best used after your water has boiled in your standard tea staineless steel pot then poured into the glass leaf tea pot.

Yes, they are standard opening size. They cannot, however, be used for typical canning. Says on the bottom of mug.

They call it "plastic glass" for the same reason they call it "unbreakable" -- it is the triumph of marketing over reality. Just as these are not glass in the common sense of the term, neither are they likely to be the victor in battle with a sledgehammer. But they are fine mugs, just about as clear as glass, and do a very good job of keeping liquids hot or cold.

I have never used that warmer specifically. But I used an electric tea kettle to heat water to nearly boiling and then warmed these in a coffee mug. No cracks. And occasionally they would come right out of the fridge and into the water. Love them!

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?

They should work well. We have All-Clad stainless lids and they do the trick...no tea pot however. The handle covers may be loose given they are universal and will fit many types of lid handles. They are secure however and avoid the need for a pot holder. Hope this helped.

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.

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