See... when I said that the quality and functionality vary a lot and that "most" used pyrex as their material I meant exactly that.
The majority of glass bowls you will find on this market are pyrex or borosilicate glass. It's the same thing pyrex is just the common brand name.
Also please find me a glass bowl from those areas. I would love to see them and know what they offer.
