How was the thermos flask originally used for?

They were the traveller’s friend. And yet the vacuum flask was created to keep things cold. It was the brainchild in 1892 of Sir James Dewar, a scientist at Oxford university who worked in cryogenics, or liquefied gases. He needed to keep the chemicals as cool as possible.

What is the history of thermos?

In 1892, Scottish scientist Sir James Dewar invented the vacuum flask. Through his work in cryogenics, he identified a need to keep a chemical placed in a flask at a stable temperature. To do this, Dewar placed a glass bottle in another larger glass bottle, and evacuated the air between the two bottle walls.

Are flasks safe to drink from?

Stainless steel flasks are not intended for long-term alcohol storage. There are no serious health risks associated with drinking liquor that has been stored in a stainless steel flask for a long period of time. The main advantage to stainless steel flasks is that they are light, tough, and portable.
