Are these made of borosilicate glass?

To the best of my knowledge, these are not borosilicate glass. They are tempered glass, highly durable. I've used these Duralex bowls (and glass tumblers) for 30 years without a single break or chip.

They are solid glass. I have had my set for almost a year now and am very happy with them.

Yes but they are fragile. We are very careful with glassware but these broke easily. Not a good purchase

They are glass, I don't think they are real crystal. The fixture is awesome, doesn't look cheap, great buy for the price!

Yes. The glass used for Lifefactory baby bottles is called borosilicate glass. Borosilicate glass is made of the following components: 80% silica, 13% boric oxide, 4% sodium oxide, and 2-3% aluminum oxide.

I think they are. They are made from heavy plastic and work quite well. No problems.

My guess is that they are the soda lime glass. Pyrex doesn't do much borosilicate glass in their kitchen cookware in the states. I hear that soda lime glass is a bit more resistant to breakage when dropping. In fact, these came in a box that was completely crushed, and a number of double wall metal pans were damaged and twisted out of shape very badly. The bowls survived without even a chip! Also judging from my mom's heavily used 20 year old set that is most probably made of soda lime (Pyrex switched in the 1940s), they can be very durable, and I don't expect any breakage.

These are made of cobalt blue solid glass, not painted. We are very happy with them.

They are definitely all glass, not sure if tempered though. They definitely are not plastic.

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!

They are glass, but not just silicon but 'borosilicate', which means they're like the same glass used for pyrex these days. This increases durability and the ability to handle thermal shock.

NO, only aluminium made ! One very rare to find is made with glass but only the top and buttom is aluminum. (ASIN: B001CJTZ54 )

I believe so they are glass not crystal... made in USA and didn't notice a warning. They are very nice glasses

Yes they are glass, and they are great, Ive used them a couple years in a row now for storing herbs I dried from my garden and they are nice and air tight.

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.

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

Unfortunately no they are not, these are made of clear glass only and they do make a pleasant table piece on any special occasion. Thank you for your interest in Angelo Gifts | Autumn Rose Wedding.
