Is the glass borosilicate? Lock n lock glass containers are.

Glasslock is one the Lock n Lock lines; if the lid has a pattern it is borosilicate; i the lid does not have a pattern on it (like the regular lids), it is not borosilicate. The ones that are borosilicate will say borosilicate on the label (but it is very tiny writing).

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.

No. It is glass and a great jar. I use it each day to drink cold water or a jar of hot tea.

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 have had two borosilicate glass containers that were labeled as freezer to oven/microwave safe shatter on me when trying to do what you ask. So, no matter how many times you get away with doing it, and no matter what the manufacturer says, be aware that shattering can and does occur.

Yes, the Modern Contemporary Glass Curio is glass only on the sides. The top and bottom are not. I do not know about adding a lock to the curio. However, I would not a lock and take away the beauty of the glass curio.

Hi - I love these containers but, they are Not Glass and Cannot go in a 425 oven. They are plastic and are great for the fridge, freezer, and microwave. Hope this helps.

Not sure. The square glass containers likely are, but the metal portion probably is not.

It is more glass-like. I am very pleased with this product. It takes patience to apply correctly.

Yes, this bottle is glass. The package included bubble wrap for protection and arrive very quickly. I'm very satisfied with the product and seller. I definitely recommend it.

Yes the bottle is glass. The plastic cap,at least on mine, didn't tighten well though. If I tried to tighten it (to keep the smell in) it would tighten a bit then the threads would miss and it would be loose again (and smell up the cupboard).

Yes. The bottle is glass and the top is metal. I've had mine for ages now. I think it keeps forever!

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
