You can still buy borosilicate Pyrex. PYREX (uppercased) is still made borosilicate, where pyrex(or Pyrex) is not.

Yup.. If I go search for Pyrex on Amazon Spain, I find the real borosilicate stuff made in France since 1922. They never decided to cheap out on the materials.

I don't think it's this easy for people in America: https://lifehacker.com/that-viral-pyrex-brand-hack-is-horses...

thanks for that tip, i have PYREX measuring cups bought over 20 years ago that are still going strong, but this is good to know if i ever need to replace them with the same quality product.
