Are they really made of borosilicate? Surprised comments say glasses are delicate/fragile.

The inner & outer glass walls are quite thin, so they are not for small children. They will shatter if dropped or hit. They do work well. They can take very hot espresso. They are 4 oz so they look empty with a single shot of espresso.

It is very bad quality, and got it with the broken one and a small hole at the base of one another

, I have not thought they are fragile. Not.easily stackable that is my main comment. Beautiful, yes, and unique. Hope this helps :)

I believe it's a blend of various forms of glass. They are delicate but have a heavy bottom. Not something you want to use for a house party but maybe something for a formal get together

They're glass, but I've bought two sets and both times the pitcher cracked over time. My glasses are still ok though.

NO, they are glass and I would say, not for children, that might drop and break. I order to use them with my crafts. Good Luck. Billie

No - the glasses are clear...the box is red - BTW, the glasses are very durable, I knock them on my granite countertop and cast iron sink, and they never break or even chip.

We've had ours quite a while now and use them frequently. None have broken yet. We wash them in the dishwasher, too. I'm still very, very happy with these glasses. Still look like new!

Dear Math, thanks for asking. These items are made of glass (apart from the absinthe spoons of course!)

Yes, they're made of glass. We use them for fermenting foods, making tea and storing food items.

They are like glass if not glass. But they don't break or chip when you drop them. If you hit them with a hammer, they'll break.

Sorry I couldn't get an answer quicker, I've been sick and haven't touched my email. These are glass. Nice and thick glass to, very well made!

I would say they are glass but a very nice glass - elegant - reflects the light. Unless you are ordering "Waterford" or a similar named brand crystal maker - most stemware is a type of glass and doesn't usually meet the exact requirements of crystal.

They are not fragile. I've broken only one out of a dozen. 4 ft drop to concrete. Easily as sturdy as any glass of like size. Slightly heavier in my opinion. Hold the cold like crazy.

Hi.I do not recommend buying these glasses. They broke after 1 day.I was nervous and threw them in the trash. The quality is very low.Andrey.

No, they are real glass, just like your normal glassware... The only difference is they're two-ply thinner glass.They will probably break sooner than they get scratches like old drinking glasses get... lolMine seem to last about 3-4 years, then they'll drop into the sink and break, or they get tapped into the icemaker on the fridge door and break, and so on.I hand wash all my double-wall glasses, however... just to be safe and cleaner.

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.

ours are definitely plastic, which is what I prefer - in our household glass would break sooner rather than later... these still look very nice, not at all foggy or scratched.
