We lost our smaller measuring cup in the move, so one of my first purchases when I got my first job was a pyrex measuring cup. I learned the hard way that the only thing pyrex about it is the logo
Heh, no worries, I just wanted to spread awareness about this issue in a cheeky way ! Though it does legitimately feels weird seeing these as a European because we only get the "real" ones here.
"True" Pyrex is made of borosilicate glass and is very resistant to changes in temperature, making it excellent for lab or kitchen use. You can tell when it's "true" Pyrex if the lettering is in all caps. If it's not, it's just regular glass.
