Any idea if this is borosilicate or soda lime glass?

Sorry, I have no idea. However they were ordered by my wife who is picky and she loves them.

Linda, sorry I do not know...These glasses have not been put to any type of heat test. The density of the glass is greater than that of a regular glass. I trust someone will be of greater knowledge/information. I am guessing they could handle boiling water with no problem...beyond that???

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

It is glass, almost feels like a plexiglass mix though. Very nice a durable, don't know how it holds up in dishwasher because I always wash my bar glasses by hand but cleans up feeling like glass.

It absolutely seems like glass to me. If it is plastic, I can't tell the difference. I'm not going to throw it to find out though. :)

I think glass, but not 100% sure. I live overseas and that containner was left in our summer home in U.S., so I can't verify.

The glass is glass. Don't know what the metal is however I returned it - not because of anything other than it is very very small. The measurements they list are misleading. Great looking item but expect it to be smaller than you may think it is.

I honestly don't know... All I can tell you is that we have had the glass on our kitchen table for over a year, and it has been a perfect replacement for the one we broke by accident. I would try to contact the manufacturer if this is important for you. We have had no issues with ours though- that is all I can tell you... Hope this is helpful.....

Glass is made by melting together several minerals at very high temperatures. Silica in the form of sand is the main ingredient and this is combined with soda ash and limestone and melted in a furnace at temperatures of 1700°C. Other materials can be added to produce different colours or properties.

I could be wrong as it could be glass. I don't look at it often. But I love it!

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

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

Actually it is kind of white frosted glass. Only the lines, as the picture show, are solid white. I hope it helps you.

I think the clear material is Lucite or some other plastic, not glass. I agree with others that's better; glass can break and when using this while cooking one can't be sure to carefully place it down every time. In addition, when I finished the salt it came with and put in new salt, it didn't work as well. I'm not sure I'm happy with the product.

It is lead crystal. Lead is used to be able to cut the designs in cystal. If it was smooth glass it would likely be lead free.

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.

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.
