• Curling is a sport in which players slide stones across a sheet of ice towards a target area. It is related to bowls, boule and shuffleboard. Two teams, each of four players, take turns sliding heavy, polished granite stones, also called "rocks", across the ice curling sheet towards the house, a circular target marked on the ice. Each team has eight stones. The purpose is to accumulate the highest score for a game; points are scored for the stones resting closest to the centre of the house at the conclusion of each end, which is completed when both teams have thrown all of their stones. A game may consist of ten or eight ends.

The curling stone• The curling stone (also sometimes rock, North America), as defined by the World Curling Federation is a thick stone disc weighing between 38 and 44 pounds (17 and 20 kg) with a handle attached to the top.The maximum allowable circumference is 36 inches (910 mm).The minimum height is 4.5 inches (110 mm). The handle is attached by a bolt running vertically through a hole in the centre of the stone. The handle allows the stone to be gripped and rotated upon release; on properly prepared ice, the stones path will bend (curl) in the direction the front edge of the stone is turning, especially as the stone slows. The handles are colored to identify the stones by team. Two popular colors in major tournaments are red and yellow. The only part of the stone in contact with the ice is the running surface, a narrow, flat annulus or ring, 0.25 to 0.50 inch (6.3 to 13 mm) wide and about 5 inches (130 mm) in diameter; the sides of the stone bulge convex down to the ring and the inside of the ring is hollowed concave to clear the ice.
Curling broom• The curling broom, or brush, is used to sweep the ice surface in the path of the stone,and is also often used as a balancing aid during delivery of the stone.• In earlier days, brooms were made of corn strands and were similar to household brooms. Brushes were used primarily by elderly curlers as a substitute for corn brooms. Today, brushes have replaced traditional corn brooms at every level of curling, but are universally referred to as brooms. Curling brushes may have fabric, hog hair, or horsehair heads. Modern curling broomsticks are usually hollow tubes made of fiberglass or carbon fiber instead of a solid length of wooden dowel. These hollow tube handles are lighter and stronger than wooden handles, allowing faster sweeping and also enabling more downward force to be applied to the broom head with reduced shaft flex.
Shoes• Curling shoes are similar to ordinary athletic shoes except that they have dissimilar soles; the slider shoe is designed for the off foot (or sliding foot) and the non-sliding shoe for the hack foot:• The slider shoe is designed to slide and typically has a Teflon sole. It is worn by the thrower during delivery from the hack and by sweepers or the skip to glide down the ice when sweeping or otherwise traveling down the sheet quickly.
Other equipment• Other types of equipment include: – Curling pants, made to be stretchy to accommodate the curling delivery. – A stopwatch to time the stones while sweeping to get a feel of the speed of the stone. Stopwatches can be attached either to clothing or the broom itself. – Curling gloves and mittens, to keep the hands warm and improve grip on the broom.
