Any idea if this is borosilicate or soda lime glass?

If they break easily, they are not borosilicate (think Pyrex) I've got Arcoroc bowls that are 30 years old. I was given some glass bowls that looked exactly the same, but they didn't have the "Arcoroc France" imprint. They were obviously fakes, none lasted more than a few months--same handling as the ones that are 30 years old. I just bought some Duralex bowls--they have an imprint are a little thicker than the Arcoroc bowls. It will be interesting to see if they hold up as well. If they can't take the dishwasher--they're fakes or just junk, they're more dangerous than useful. I think an imprint is a good indication if they're right or wrong.

No idea, but, I will tell you that the glass is fragile and not very dishwasher friendly. We bought a second load of these because the first ones were chipping. Need to be hand washed.

I can't say. All I can tell you is that the dishes are pretty and versatile but cannot take careless or rough handling. I have lost two but plan to purchase more for the Holidays because they complete a beautiful table setting.

It is glass. We have had no issues with this and have found it easy to keep clean.

I could not tell you as it is not Glass. These are supposed to be questions about Glass. Sorry.

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'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.

NEW INFORMATION. I wrote directly to Libbey Glass and asked the question. Here is the response I got pasted from their reply: "Thank you for contacting Libbey glass. The material is BPA free. It is a polyethylene material." I can believe this; the material behaves like polyethylene of which there are many versions, and polyethylene is used in many medical implanted devices as well as a great deal of hospital equipment, e.g. IV bags and tubes and also in public water supplies. It's okay. This is my previous comment: The plastic parts are definitely NOT silicone. I've not yet been able to determine for certain what they are. I'm intrigued by Erika's comment suggesting there are two versions of the jar, one of which may have a silicone seal. The ones I received from Amazon do not have silicone seals, but polyethylene is perfectly safe in my opinion.

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.

It is glass. If it is plastic, it's a very good imitation of it. It looks and feels like glass, but I can't give you an exact chemical composition of it to show it's actually glass.

I had one shatter on me (it was more like 'exploded' than shattered) and I switched to the true borosilicate glass. In fact I got my borosilicate cookware from Amazon. Look for the Marinex brand.

Definitely not glass---it's lightweight plastic. Don't know why the weight is listed so high.

according to Consumer Reports, January 2011, borosilicate was phased out in the 1980's. The claim is that the new glass will not shatter any more easily

Absolutely--It's solid glass. I'd probably avoid dish detergent that's labeled "lemon" because that can make any glass cloudy.

This was hard to tell because the black plastic covers the bottom outside so you can't tell visually. But I drained it and felt around inside (there are some odd ridges and bumps) and it all felt like glass. Hope this helps.

On the Grosche website, they only mention that it is borosilicate glass, just as Amazon indicates. I do not know if that means it is lead-free, though. I recommend emailing them at sales@grosche.ca to verify.

This one is glass. I've had it about a year with no breakage. Not sure where to replace it other than contacting the company.
