They are old and steel and are glass lined. I had one too. Poured in a pot of coffee one winter day and SHATTER.

I am referring to the green stanley brand one. I do not know about the other.

I can see the seam where the metal is joined/welded up the side of the interior of the Stanley thermos. I'm pretty positive it is not glass....perhaps you had a different one. Thanks for the warning just the same.
