How to keep tea hot for a long time
History of the invention
As always, everything is brilliant - simple and created, most of all, by accident. So, in 1892, the scientist James Dewar created a vessel for the storage of experimental reagents. It was a vessel with double walls, between which there was no air, only a vacuum. Also, a thin layer of reflective silver was applied to the outer sides of the surfaces of both vessels. Of course, the scientist was not even aware then of the versatility and utility of his invention. But his student R. Berger saw in it a household and financial benefit. It was Berger who in 1904 put this appliance on mass production and gave it the name we use today.
Subsequently, for convenience, Dewar's student refined the design of the thermos and came with a lid and a cup. So the student outgrew his teacher and began to earn considerable money for the manufacture of this apparatus. Thermos, a company that manufactures thermos flasks, started working and is now operating.
