A samovar (Russian: самовар, pronounced; literally "self-boiler" is a heated metal container traditionally used to heat and boil water in and around Russia, as well as in other Central, South-Eastern and Eastern European countries, in Iran, Kashmir, Turkey and Hadhramawt eastern Yemen. Since the heated water is usually used for making tea, many samovars have an attachment on the tops of their lids to hold and heat a teapot filled with tea concentrate. Samovars are said to have been invented in Central Asia, though their origin is a matter of dispute. For example, some argue that it is purely a Russian invention given that the samovar appeared in Iran not later than in 18th century, and it bears the same Russian name "samovar" which translates to self-brewer.
Samovars come in different body shapes: urn- or krater-shaped, barrel, cylindric, spherical.
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 teapots.
A traditional samovar consists of a large metal container with a faucet near the bottom and a metal pipe running vertically through the middle. Samovars are typically crafted out of copper, brass, bronze, silver, gold, tin or nickel. The pipe is filled with solid fuel to heat the water in the surrounding container. A small (6 to 8 inches) smoke-stack is put on the top to ensure draft. After the fire is off a teapot could be placed on top to be kept heated with the passing hot air. The teapot is used to brew the заварка (zavarka), a strong concentrate of tea. The tea is served by diluting this concentrate with (кипяток) kipyatok (boiled water) from the main container, usually at a ratio of about 10 parts water to one part tea concentrate, although tastes vary.
