Are these glasses Dura Tuff heat treated?

I am not sure. I do know I have had these for 4 months give or take with heavy use and they still look new. They are solid.

I am not for sure, but the website says DuraTuff. I know I absolutely love these glasses and they are extremely tough. Here is the link http://foodservice.libbey.com/Product-Repository/Iced-Tea-Glass5.

I use these glasses in the Microwave for Hot Chocolate, and Warm Bloody Mary's, I haven't had any problems with them breaking, I also put them in them Dishwasher every Day, Theirs Nine of us so they get used quite often, The only time they break is when the kids drop them on top of each other in the sink, but this only happens occasionally. Hope this helps.

I really have no idea. I would suggest that you go to the Libbey website or send them the question.

I'm sorry; I do not know positively. I do know that glasses the are designed to be used in restaurants are usually "Dura Tuff" treated. These state that they are "restaurant quality", so let's assume they are treated. To be positive, I'd contact Libbey.

No. These glasses are extremely poor quality. I wore them once and returned them because they feel so plasticky and about to break. I recommend against them. Good luck

As far as I know they are not! There was no note with them stating they were! They are very clear and easy to use! I find them very comfortable with my glasses! If you buy a pair I hope you enjoy them as much as I do!

Yes they are. I got a pair of my own for my car, and I LOVED them. They are extremely durabale and are coated with polyethylene on the back wich is like the silver duck tape you'd use for pressure-sensitive things and they are weather-resistant. I have drove with those over 90* F and under 30*F and through heavy storms and dry humidity, and they are still in perfect condition. If you really want those, I highly recommend getting them, and don't worry about the air blubbles you might develope upon putting them on, cause the heat will flatten them out. Hope I helped answering your question!! :)

They are not painted and appear to be colored through and through. They are very durable glasses and none have broken, so I can't determine if they might be considered stained glass.

Yes, they are BPA free. I love mine -- except they will crack if dropped on a hard surface. The crack hasn't shown any effect on keeping beverages hot or cold.

I have not done this, but the flasks are borosilicate (pyrex type) glass and I would assume that they are.

I believe they are hot-dipped. Regardless, in two years of use, they haven't shown any signs of rust.

I'm pretty sure they are. I would suggest checking the Tuffbuilt.com website to be sure.

No- the indentations are only felt on the exterior. It's completely smooth on the inside. They're great glasses. Heavy enough but not overly.

I assumed they were, but after washing 2 of them in the dishwasher I discovered they were not. But aside from that, I love them. The only glasses anyone in my house wants to drink out of anymore!

They are acrylic...I would prefer glass but for around a campfire, I guess acrylic is okay!

They are glass - I have used them for years as everyday glasses. Just the right size.

Yes. these glasses are very thick and handle heat well. Shouldn't be a problem

I've had mine for several years, but they are glass. The only thing I've ever heated is butter to soften or melt without any problems.

Yep it is. They were good quality too. I bought them some time back though 2 yrs ago. Mine were glass.I still have em and they work fine.

Yes these lenses are glass. My right side shattered from a rock. I picked up a shard and it was definitely glass.
