line of flasksThe original vacuum flask made famous by the Thermos company had a glass liner that was hand-made by a glass blower.

The thermos flask arrived the right time in history to be imminently useful to a new class of workers, employed in mass manufacturing. That it could keep their soup hot for hours must have seemed like magic to the hardworking German workers who were the first purchasers of flasks. The fact that it could itself be inexpensively mass produced, didn’t hurt either.

It is unusual to find a glass lined thermos flask in stores today, as the durability of stainless steel has made it the material of choice for most modern vacuum flasks.
