The Material Uses On Curling
The stone from which curling is made is not just any stone! It's made from natural granite in Scotland that doesn't contain mica, and all the natural granite in the world that makes good curling. Both from an island off the coast of Scotland and only the Scots have the know-how to make the best curling in the world.
Curling is named after the unique turning that occurs at the end of the stone's path on the ice. The curling stone, or rock, is made of dense polished granite from Ailsa Craig, Scotland, and in the Olympics, each rock weighs 19.1 kg (44 lbs). The bottom of the stone is concave so that only the outside ring, called the running band, is in contact with the ice. This minimizes the friction and allows the stone to slide farther.
