The samovar, which, literally, means "self-boiler," is made of brass lined with tin, with a tube in the centre. In fact, it resembles the English urn, except that in the centre-tube red-hot cinders are placed instead of the iron heater. Of course, the charcoal, or braise, has to be ignited in a back kitchen or court-yard; for in a room the carbonic acid proceeding from it would prove injurious.
If you are an experienced traveller you will be able to reply in the affirmative, for good tea can be bought only in certain well-known shops, and can rarely be found in hotels. A huge, steaming tea-urn, called a samovar etymologically, a "self-boiler" will be brought in, and you will make your tea according to your taste.
