I would hazard to guess that all consumer type thermoses use pyrex
type glass or something similar.  After all, they're made to take
boiling hot coffee.  I once transported liquid nitrogen in a "K-mart"
type consumer thermos with no problem at all.  It kept it chilled, and
the thermos was undamaged.  I was a college student at the time and my
dad, before hand, also claimed it would not work.  :)
