Are these Borosilicate Glass or Soda Lime Glass? Guessing soda lime based on price. Just checking.
thank you

MtnaddictionThese are made of tempered soda lime glass. They are more resistant to shocks, but do not handle rapid temperature swings as well as borosilicate. You mainly find borosilicate in lab equipment.

kstokley"You mainly find borosilicate in lab equipment." I think you mean here in the states. Correct me if I am wrong but PYREX outside the states is still made out of borosilicate. Which begs the question, what is the advantage of Duralex to pyrex, other than price, to us here in the states? I seem to recall on Corning museum videos that borosilicate, world wide, is still the most produced glass.

MtnaddictionNot sure if the following link will help you. They specialize in borosilicate cookware.

ChicagoWayNice. Thanks for the link. My parents use the older Pyrex which is borosilicate and it has never given them any problems

MtnaddictionI am old enough to have had a few pieces. My mother had more. i can't say I am found of the soda lime and I am sure you have seen the Consumer Reports video. I want to point out that neither pyrex (which is sold by World Kithcens LLC I believe) nor PYREX (which is made in France) have any association with Corning now.
