Just an FYI: Borosilicate glass is and has always been very easy to break from physical impact. The og Pyrex was no different. Pyrex changed it to Sodalime glass because modern everyday usage of glass cookware saw much more breakage from slight drops or impacts.

Yes, sodalime is much more sensitive to temperature gradients but we just don’t make many frozen casseroles anymore or really have a need to take a dish from a freezer to an over like they used to.
