The Olympic curling rock, also called stone, weighs 19.1kg or 42.1lbs. It is made of rare, dense granite that is quarried on Scotland's Ailsa Craig.
Other curling equipment:
- Rink- it is 42.07m long and 4.28m wide with a target or house at either end
- Ice- for indoor tournaments the artificially created ice has its surface sprinkled with water droplets which freeze into tiny bumps on the surface. Called "pebbled ice", this surface helps the stone's grip and leads to more consistent curling
- Broom or brush- there are two types of brooms, a brush or "push broom" and a corn/straw/Canadian broom
- Shoes- special curling shoes are common; shoes should grip the ice well
