Curling stones

Types of curling stones

Curling stones, also called curling rocks, are granite stones weighing 42 pounds or about 19 kilograms. They are used in the Olympic sport of curling, where players slide the stones on a rectangular sheet of ice toward a target area at the opposite end called the house.

These stones are made from two types of granite sourced from specific quarries. The majority of the curling stones are made from a rare, blue, speckled granite called Blue Hone granite. It is obtained from the Ailsa Craig Island quarry. The other granite used for curling stones is a red and gray granite called Anvil Island granite. It is mined from the Anvil Island quarry. Both types of granite have unique properties that make them ideal for curling stones. The curling stone's handle is made from either wood or phenolic resin. The stone is designed to last for decades and is an important part of the curling game.

There are two main types of curling stones:

• Skip's Stone: The curling stone is also called the skip stone or the target stone. It is the stone that the skip or captain of the curling team throws towards the house target. It is usually heavier than the other stones. The skip stone weighs 20 kilograms, while the curling stone weighs 18 kilograms. The additional weight helps the stone achieve the curl and reach the target. The curling stone is made from either Ailsa Craig or Anvil Island granite. It has a distinctive running edge that helps it curl when thrown. The running edge is shaped like a crescent moon. It is further divided into two parts: the band and the groove. The band allows the stone to slide on the ice, while the groove creates the curl. The skip's stone is painted in different colors to distinguish it from other stones.
• Team's Stone: Curling stones are also referred to as player's stones, team's stones, or house stones. These are the stones that the other members of the curling team throw towards the house target. They are similar to the skip's stone and made from the same granite material. These curling stones have a different handle color or curl pattern to distinguish them from the other team's stones. The curling stones are used to accumulate points by getting as close to the center of the house as possible.

Scenarios of curling stones

Curling stones are essential in the sport of curling, where they are used to slide on a sheet of ice towards a target area. Here are some usage scenarios for curling stones:

• Competitive Curling Matches: Curling stones are primarily used in competitive curling matches, where teams take turns sliding them toward the target (the "house") on the curling sheet. The objective is to have the stone stop closest to the center of the house, with points awarded based on the proximity of the team's stones to the center compared to the opposing team's stones. These matches occur at various levels, including local clubs, national championships, and international competitions such as the Winter Olympics.
• Practice and Training Sessions: Curling clubs and teams use curling stones during practice and training sessions to improve players' skills, including delivery technique, weight control, and sweeping effectiveness. Players practice different types of shots, such as draws, hits, and guards, to refine their techniques and strategies in preparation for competitive play.
• Curling Schools and Clinics: Curling stones are used in instructional programs, schools, and clinics to teach the fundamentals of curling to beginners and experienced curlers. Instructors use curling stones to demonstrate proper delivery, sweeping techniques, and the effects of curling on the stone's trajectory. Participants then practice with the stones to learn and improve their skills under guided supervision.
• Ice Curling Stone Maintenance: Ice makers and curling clubs use curling stones to ensure the ice conditions are suitable for curling. They practice game simulation to check for any irregularities in the ice surface and make necessary adjustments. This ensures that the stones will curl appropriately and predictably during matches. Additionally, regular maintenance of the stones' handles and running edges ensures their optimal performance.
• Demonstrations and Exhibitions: Curling stones are used in demonstrations and exhibition events to showcase the sport of curling to spectators. These events often feature skilled curlers performing impressive shots and displays of curling's strategic elements. These events aim to promote the sport, encourage participation, and entertain audiences. Additionally, curling stones may be used in corporate events or team-building activities where participants try curling as a recreational sport.

How to choose curling stones

Business owners should consider the following factors when purchasing curling stones for resale:

Functions, Features, and Design of Curling Stones

Features

• Durability

  Durability is an essential feature of curling stones because these stones are heavily used and need to last for many years. Made from high-quality granite, curling stones can resist the wear and tear of regular use and the impact of accidental drops or bumps. In addition to this, the stones must be capable of withstanding extreme temperature changes, as they are often stored outside or in poorly heated areas. To further enhance the durability of curling stones, many manufacturers apply protective coatings or treatments that help prevent scratches, chips, and other forms of damage. This ensures that the stones remain in excellent condition and retain their playing characteristics over time.

• Handle design

  The design of curling stones' handles is an important feature that affects their usage in curling. The handles are normally made of plastic or wood and are designed to be strong and comfortable to hold. Most handles have a textured or ribbed surface to provide a secure grip, which is important when delivering the stone. Some handles also have ergonomic shapes that fit the hand more naturally, reducing fatigue during play. In addition, the handles of curling stones are designed to be easily detachable, which allows for easy transportation and storage of the stones. Overall, the design of curling stones' handles is a crucial aspect that enhances the game's convenience and efficiency.

Functions

• Direction control

  Handle on a curling stone allows the player to control the direction of the stone after it has been released. The handle is twisted before throwing the stone, which makes it possible to achieve the desired trajectory. Thus, handles are important for ensuring that the curling stone reaches the target during play.

• Stone movement

  The handles on curling stones allow players to control the movement of the stone. Players grip the handle tightly and apply the required force when delivering the stone to achieve the desired movement.
