Billiard table – a table constructed and adapted for playing billiards on it. Billiard tables of various dimensions can be encountered, which usually has to do with the variety of billiards that is played on them. The billiard table is made up of an overall frame, and a plate which is mounted on it. The plate is covered with cloth, or baize, and cushions are mounted on each side of the table. In the table's corners, and in the center of its longer sides, there are pockets. A billiard table can have 4, 6 or 8 legs, depending on the dimensions of the table and plate. Additionally, a special mechanism which makes for-profit use of the table possible can be built into it. The stone plates used in the production of billiard tables are from genuine Italian slate. In tables intended for strictly recreational use, the plate may be made from other composites, granite slate or wood. The cushions are made from an elastic material, such as vulcanized rubber. Usually, just as the plate of the table, they are covered with cloth. The cloth with which the plate of the table is covered is often called felt, although it's made from wool (pure or with an addition of nylon), and the color of it seen most often is green. The cloth is an important element, as it has a significant influence on the speed at which the billiard ball rolls, and its rotation. The playing surface is rectangular, twice as long as it is wide. The size is often given in feet, sometimes specifying only the length (for instance, a 7-foot table refers to a size of 3,5 x 7 feet). Table sizes ranging from 6 to 12 feet may be encountered.
