Curling, also known as "ice skating" or "ice chess", originated in Scotland in the 16th century. At that time, a game similar to groundball was played on the ice. It was not until the establishment of the Scottish ice skating club in 1838 that the formal rules of the game were formulated.

Curling project has attracted more and more attention and love. Did you know that curling is actually an "aristocratic sport", not to mention the cost of equipment such as ice brushes and curling shoes, the cost of curling itself is not low. The curling used in international competitions is about 2000 dollars per curling bottle.

As an ice throwing event, curling has special requirements for raw stone materials. Firstly, the stone needs to be hard, and secondly, it is required not to be cracked under low temperature conditions. The most common hard rock is granite. Today's curling is mainly made of granite without mica.
