The kettles used by street vendors are double layered, with fuel in the inner layer in the center, and water in the outside layer similar to samovars.
As explained in the introductory narration, the two would meet every evening to drink tea from the cub's samovar, which was heated on a fire of juniper twigs.
That year they produced 423 samovars.
A typical samovar consists of a body, base and chimney, cover and steam vent, handles, faucet and key, crown and ring, chimney extension and cap, drip-bowl, and teapot.
It was supper time and all of us children sat at the table, mama pouring tea from the samovar boiling on the table...
The traditional implement for boiling water for tea used to be the samovar (and sometimes it still is, though usually electric).
Very soon they became not just practical utensils, but also works of art, just like samovars that were used for boiling water.
Though traditionally heated with coal or charcoal, many newer samovars use electricity to heat water in a manner similar to an electric water boiler.
