The Role of Ailsa Craig Granite in Olympic Curling Stones

The Role of Ailsa Craig Granite in Olympic Curling Stones

Post by : Bianca Haleem

Situated 10 miles (16 kilometers) off Scotland's southwest coast, the uninhabited Ailsa Craig island remains pivotal for the Winter Olympics as the source of the rare granite essential for curling stones.

Kays Curling, located in Mauchline near Ayr, exclusively extracts granite from this island. The company has manufactured stones for the Winter Games since curling became an official event in 1924 at Chamonix and has maintained this tradition since the sport's return in Nagano in 1998. Co-owner Jim English claims that all gold, silver, and bronze medals awarded since then likely feature their stones.

During inspections on Ailsa Craig, English checks the granite boulders for any cracks or surface imperfections. The island's granite includes two distinct types: the common green, which forms the stone's main body, and blue hone, celebrated for its waterproof and dense characteristics, used on the stone's running surface. These qualities are vital for curling, where stones endure intense collisions and severe cold without shattering.

Geologists suggest that the microgranite on Ailsa Craig originated from volcanic activity millions of years ago. Its elasticity helps absorb shock during impacts, while the blue hone guarantees a smooth, reliable glide on the ice. Experts assert that this granite type is unique to this location.

Extraction techniques differ; common green granite is typically collected in large pieces, sometimes weighing up to 10 tons, while blue hone demands precise extraction using gas charges. This method fractures the rock along natural fissures, producing smaller blocks under two tons. The stones are then transported to Girvan Harbour, shaped into circles, and further refined by Kays. The final stones average 42 pounds (19 kilograms). A single-insert stone retails for £704 ($930), while a double-insert version is priced at £750 ($990). A complete set of 16 double-insert stones costs £12,000 ($15,860).

Environmental conservation is prioritized on the island, which hosts significant populations of gannets and gray seals. Measures are in place to safeguard the local wildlife, including the use of rat traps to deter rodents.

Globally, curling's popularity is on the rise. Kays produces between 1,800 and 2,000 stones each year, with Canada being its largest market. Demand is also increasing in countries like China, Japan, and South Korea, particularly after the 2022 Beijing Winter Olympics. Interestingly, Kays has supplied stones to unexpected places such as Qatar and Antarctica, integrating curling into luxury travel offerings.

As the Milan Cortina Winter Games approach, Ailsa Craig's distinctive granite will again play a central role in Olympic curling, highlighting the island's enduring impact on the sport.
