> Instead of being made with Pyrex borosilicate glass, it was cheap soda-lime glass that couldn't stand up to heating. I never noticed the difference. American-made[1] "genuine" Pyrex is now also soda-lime, so just the name isn't proof enough any more, at least for cookware rather than labware. [1]: and I think some stuff found in the UK, as I have a Pyrex-brand jugs and dishes that have got a distinct blue hue when seen edge-on.

Remember, kids, the purpose of trademarks is to prevent consumer confusion! When a person buys PYREX®, they know it's a name they can trust.

  Yeah: Kinda makes you wish there was a good system for customers to sue a company into dropping a trademark that's being used to mislead.

  Yup! PYREX = good and Pyrex = sub-par.

No, the lab-grade stuff is still borosilicate, only the consumer products were gimped.
