The thermos flask. Heat from a bottle.

The thermos flask. Heat from a bottle.

In 1903, glass specialist Reinhold Burger invented the thermos flask. The creation of a container that could preserve the temperature of the liquid inside it without the use of chemicals was revolutionary for its time. The thermos flask quickly established itself as an extremely useful invention that even today remains an indispensable part of day-to-day life. In the museum town of Baruther Glashütte, a glassblowing village in Brandenburg with a nearly 300-year history, there is an exhibition dedicated to the thermos flask and its success story.
