These kind of thermoses have a replaceable glass liner, so the standard is to replace it when it breaks. Replacement glass liners are still made for some brands today, though asbestos free. The oldschool glass lined thermoses are still semi-common in Finland and are made by a company called Airam. I’ve got one myself.

Not the all glass liners contained asbestos, but some did and there is really no way to tell.

I remember there being liner replacements available long ago but I haven't seen one retail in the US in a very long time. That and the cost differential wasn't really much different from just getting a new thermos, and for me the price difference made it barely worthwhile to mess with it.

I switched to Stainless steel 50 years ago, 1972, and I'm still rocing that one. No ragrats. ¯\_( ͡❛ ͜ʖ ͡❛)_/¯
