The Pyrex ware in the U.S. is no longer made by Pyrex, nor are they made of borosilicate. I discovered this yesterday, while attempting to make yogurt. Some jerks bought the name, and the name only. Don't support them.

@CivicFiberglassDoor The pyrex in lower-case letters are manufactured by an American company (Corelle Brands.LLC) and it's made from tempered soda-lime glass, not Borosilicate, and that's why it isn't as heat resistant as the original Pyrex glassware. The original Pyrex made out of Borosilicate, are still being manufactured here in Europe by a French company (International Cookware SAS) but unfortunately for you Americans, their products are only sold in Europe, Middle East and Africa.

Even having seen this, something tells me that I'll still be handling a microwave container made out of this glass overly carefully for a long time. Having glass shatter due to sudden temperature change more than once and in one instance quite violently kind of leaves a trace...

... I've never seen coffee pots that look like that. How do you hold them? Do they add handles afterwards? OH! Are those what they put in coffee presses? Anyway. Thanks for the video :)
