Curling is a very famous ice sport in which players are required to strike the stones into a designated concentric circle. The game is played between two teams where they alternatively take a chance to slide heavy stones (rocks) in the curling house. The curling broom is the primary equipment used for sweeping the surface of the ice sheet. The primary objective of the broom / brush is to sweep on the ice surface in front of the sliding stone. The brooms are also used as a balancing aid at the time of delivery of the stone. Nowadays, "Frankenbroom" is majorly used in official matches. The brush fibres of Frankenbroom are made with artificial materials and have a smooth surface on one side and rough on the other side.
The curling brushes consist of long hair brushes made from artificial fibres. The modern curling brush handles are made from fibreglass or carbon fibre having a hollow tubular structure. The handles are intentionally left hollow to make them durable and lighter in weight that also aids in fast sweeping and maximum downward force to the broom’s head. The carbon fibre brooms are majorly preferred due to their ultra-light and ultra-strong features. The modern brooms are aided with honeycomb construction, making it more functional.
The handles of the brushes are usually 48 inches (120 cm) long and have a diameter of one inch (2.5 cm).
The curling brooms during the initial days (prior to 1950s) were made from corn strands which were similar to the household brooms. Later in 1958, Fern Marchessault of Montreal modified the broom by inverting the corn straw at the centre of the broom. These corn style brooms were referred to as the Blackjack. Then to increase the durability, artificial brooms were manufactured with the aid of man-made fibres. Examples of these types of brooms include Rink Rat and Scottish brushes. Later in the 1960s, some professional curlers proved the point that curling brushes could be equally productive as the corn brooms. By the 20th century, the brush brooms have taken over the corn brooms completely so corn brooms can now be seen rarely being used by the curlers.
