Basically, there are a large number of instances of newer Pyrex baking dishes literally "exploding" under normal use. Google "exploding Pyrex" and you'll see hundreds of stories of people taking glass shrapnel in the arms, hands, and legs.
So now I'm skeptical about using my Pyrex baking dish anymore. Basically from what I've read, Corning sold the Pyrex name to World Kitchen in 1998. After that, they changed the glass composition from borosilicate glass (same thing they use for chemistry equipment, super heat resistant) to soda lime, aka regular old beer bottle glass. Which isn't a big problem in itself if the glass is tempered properly, but one website had some of the new dishes analyzed, and a number of experts said the glass wasn't properly tempered. When it isn't tempered properly, it tends to explode into large sharp shards. Basically, they took a good thing and cheapened it until it was junk.
I've been looking into getting some vintage Pyrex on FleaBay, or else getting some Luminarc. Luminarc is a European brand, but still uses borosilicate glass.
