Any idea if this is borosilicate glass?

I'm not sure, but Sur La Table has a video that says it is? http://www.youtube.com/watch?v=yHsu0D-WiC4 They seem sturdy -- I use them a lot. One came chipped, but the rest have held up falling on a hardwood floor... hope that helps.

I do not see any markings that indicate that these lids are BPA-free. The bigger concern is the composition of the glass itself. Corning divested its interests in 1998 and, with that, the original formula of borosilicate glass was changed to soda-lime glass, a cheaper and more volatile composition. http://en.wikipedia.org/wiki/Pyrex. I have both the original and current version of these ribbed glass storage bowls. The earlier is heavier and will likely outlast the modern version by generations.

I would not say glass but it is clear not that frosted kind sold in building supply stores

The glass is gorrilla or gorrilla like. The frame is aluminum. This is a well made fake.

Yes, borosilicate glass can be microwaved, but being sealed double walled it should not be. If any expansion of gasses occurs between the walls of glass due to superheating then the glass can shatter.

Im not sure but I think its acrylic. It seems thick, but I dont think its glass.

It is clear glass. the element is where the amber comes from in the picture. Not the glass.

I purchased this for someone else, and they are sure it's glass. It was shipped very well packed which I assumed they wouldn't have done if it were plastic. Either way, it's a neat thing and has many possible uses besides holding tea.

Pretty sure its glass (I've cracked it), but not sure if its gorilla glass.

Corning and another glass manufactures around 20 years ago change material for cook wears from soda lime to borosilicate. Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion, making them resistant to thermal shock, more so than any other common glass. So, I don't know why you mention ceramic.

It is definitely NOT plastic. It is vitreous glass. It is beautiful, hard and resists high temperatures, but it is not unbreakable. It tends to shatter rather than break if it is dropped. In 30 years I've broken only 2 or 3 pieces.

No, it is not. And glass is very thin, broke when placed a little too hard on granite counter.

to the best of my knowledge its real glass.I've replaced mine twice and if the glass breaks during removal it breaks just like real glass. I hope this was helpful.

This is Ruthy from The Handy House. No it's not glass. They need to correct that. It is correct on our website and details. I will let Amazon know so the can do that. Thank you!

It's glass. These are usually for food storage. I can't imagine Libbey not meeting those requirements.Libbey would need to be contacted to find out specific information.

Yes, it certainly does appear to be be glass. It looks like it, feels like it and my guess is that it may be about 1/4 inch thick.

Yes. I reviewed this at one point, what they call "Crystal" I call molded glass. It is nice enough, but I wouldn't call it crystal. it is a knock off.
