FAQ
A curling stone is the piece of equipment that curlers will throw during a game of curling. A plastic handle is attached to each curling stone for players to grip when they are delivering the stone. During an end of curling, each team will throw eight stones, for a total of 16 stones.
What are curling stones used for?
Curling stones are thrown down a 150 feet long sheet of ice during a game of curling. After they are thrown, two other curlers sweep the stone as it travels down the ice. At some arena curling clubs, the curling stones are also used to smooth out the pebble before curling begins. This is done to cut the top of the pebble for a flat, but textured playing surface. If the ice isn't completely level, a blade may further dish the ice, but curling stones will not do that.
Why does a curling stone curl?
In general, the physics of curling hasn't been studied well but we do know that there is some friction between the curling stone and the ice. This friction acts as a source of heat, which melts a small layer of the pebble. Since the front of the curling stone 'sees' the pebble first, it encounters a higher frictional force than the back of the curling stone. The additional friction at the front of the curling stones allows the back part to move faster. This frictional force differential creates a velocity differential, thus allowing the stone to move laterally.
What colors do curling stones come in?
Curling stones come in one color, gray, because that is the color of the granite that is used to produce all curling stones. The curling stone handles with red or yellow
