    Unless it is broke why would you try to recycle it. A lot of people collect pyrex like I do. LOL

    New Pyrex is just not as good. My boyfriend took it out of the oven and was cleaning off the stove while it cooled and the wet rag touched the Pyrex and it shattered. I will never get rid of my old stuff. Not to mention dinner was ruined.

      This article describes the change in the glass formula. Since the 90s, Pyrex glassware is made of soda lime silicate glass instead of borosilicate. It is less resistant to thermal shock but supposedly more resistant to being dropped. It is also cheaper to manufacture. I use my newer Pyrex bowls mostly for ice cream, instant oatmeal, and guacamole (using the ones with tight lids), not cooking. They are thicker and I haven't had a problem. My old bowls made using the old formula all broke from being dropped while cleaning. For cooking, I still have Pyrex and Corning Visions cookware from the before the formula change.
