They make a subset of the product line, and don't make it of
borosilicate glass, which is what is generically refered to as Pyrex.
So, even if they did make a pitcher, it wouldn't be suitable to use
with boiling water. There are other makers of borosilicate glass
stuff for the kitchen, though, so look around.
