Professor Bradt says the glass as it's presently tempered is "very much more susceptible to fracture or breakage from temperature changes than the original Corning Pyrex, which is the classical oven-to-icebox glass."

A recent unrelated thread on glass types has me revisiting this to write a small epilogue. (There was a related later thread.) AFAIK the scientific article "Shattering Glass Cookware", published by the American Ceramic Society (Sept 2012), was never mentioned.

Within a few months of publication, World Kitchen sued the out-of-state authors (one of whom just happens to be the quoted Prof. Bradt) and the editor, and demanded that the article and references to it be scrubbed, even though few if any members of the general public (including us) had seen or heard of it; characterizing it as defamation. Apparently they did not choose to sue the much more widely seen Consumer Reports, CBS, or NBC for some reason.

It took 3.5 years of legal wankery (and the costs that come with that) for the case to be decided in favor of the defendants after a bench trial. Plaintiff won a small victory, in the contents of 5 of the trial exhibits being sealed by the court. Defendants (and presumably the plaintiff) argued that these contained information which would be damaging to World Kitchen if they became known. A class action suit was attempted by consumers in 2018, but last year these plaintiffs moved to drop their case, without further explanation.

FWIW, it is said that there were 2 reports made to the CPSC about this shattering in 1999, and 144 in 2011. World Kitchen has since been renamed (twice) and Pyrex kitchenware is owned by one of the many companies in the business of buying famous US names to capitalize on the brand, to no doubt Make Them Great Again (e.g. Schwinn, Heinz, Remington, Hoover etc.) by sparing no expense to make quality merchandise rather than racing to the bottom and/or financing a golden payday for their executives.

PS this only applies to the US product; Pyrex kitchenware made elsewhere is from a totally different company who still uses borosilicate glass.
