Nooooooooooo!!!! Pyrex is not ever safe to freeze. Your answer no doubt comes as a surprise to all the cooks who have been baking casseroles in Pyrex, cooling them and sticking them in the freezer. After that they can go directly to the oven or be defrosted first. Ask the Pyrex people!

Pyrex is the trade name of a Corning low thermal expansion glass. All Pyrex is glass, not all glass is Pyrex.
That is a great question!!!! Pyrex used to be a form of borosilicate glass which was and still is prized for its inert properties. Meaning it doesn't contaminate other chemicals or be contaminated easily . I guess the question is can you get it cleaned out of the toxic substance? The other problem is Pyrex brand kitchenware hasent been made of true pyrex for some time and is not as inert as it once was. Is it pre or post pyrex pyrex? Its hard to tell. The safest way to be safe is scap it unless your sure. David Custome Glass Maker/Caster
