A marble is a small spherical object often made from glass, clay, steel, plastic, or agate. These balls vary in size. Most commonly, they are about 13 mm in diameter, but they may range from less than 1 mm to over 8 cm (3 in), while some art glass marbles for display purposes are over 30 cm (12 in) wide. Marbles can be used for a variety of games called marbles. They are often collected, both for nostalgia and for their aesthetic colors. In the North of England the objects and the game are called "taws", with larger taws being called bottle washers after the use of a marble in Codd-neck bottles, which were often collected for play. These toys can be used to make marble runs, a form of art, or they can be used in marble races.
