    Stationary tandoor is a large ceramic pot (hemisphere volume from 0.25 to 1 cubic
meters) with a round opening in wall or the bottom (diameter approx from 0.5 up to
0.7 meters). Traditionally it is put in the yard on a clay platform upside down. External
walls are coated with thick layer of wet clay. This is done to increase thermal heat
capacity of stove.
    Tandoor should be thoroughly heated before usage with firewood or brushwood.
The same orifice is used to put firewood, remove ashes and put bread. As soon as
all firing has burned down the walls of tandoor should be cleaned of thin coating of
burning. After that products to be baked are attached to them with quick movements.
They get done at the expense of heat preserved in thick walls of tandoor. Special
scoop and hook with long handles are used to take the products out of tandoor.
