- Ice rink
icerink is a frozen body of waterwhere people can ice skateor play winter sports. Some of its uses include playing ice hockey, figure skatingexhibitions and contests, and iceshows.
icerinks consist of, or are found on, open bodies of watersuch as lakes, ponds, canals, and sometimes rivers; these can only be used in the winterin climates where the surface would freeze thickly enough to support human weight.
Artificial rinks can also be made in cold climates by enclosing a level area of ground, filling it with water, and letting it freeze.
Snowmay even be packed to use as the containment material.
In any climate, an arena
icesurface can be installed in a properly built space. This consists of a bed of sand, or occasionally a slab of concrete, through (or on top of) which pipes run. The pipes carry a chilled fluid (usually either a salt brine or waterwith antifreeze) which can lower the temperature of the slab so that waterplaced atop it will freeze. Such rinks were developed in the late nineteenth century, the first being the Glaciariumin London. [Martin C. Harris, "Homes of British Ice Hockey"]
Modern rinks have a specific procedure for preparing the surface:
*With the pipes cold, a thin layer of
wateris sprayed on the sand or concrete to seal and level it (or in the case of concrete, to keep it from being marked).
*This thin layer is
painted white or pale blue, for better contrast; markings necessary for hockey or curlingare also placed, along with logos or other decorations.
*Another thin layer of
wateris sprayed on top of this.
iceis built up to a thickness of 2-3 centimetres (approx. 1.2 inches) by repeated flows of water onto the surface.
Periodically after the
icehas been used, it is "resurfaced" using a machine called an ice resurfacer, commonly known as a Zamboni [http://www.zamboni.com/] . For curling, the surface is 'pebbled' by allowing loose drops of cold waterto fall onto the iceand freeze into rounded peaks.
Between events, especially if the arena is being used without need for the
icesurface, it is either covered with a heavily insulated floor, or melted by heating the fluid in the pipes.
A highly specialized form of rink is used for
speed skating; this is a large oval (or "ring") much like an athletic track. Due to their limited use, speed skating ovals are found in much fewer numbers than is true of the more common hockey or curling rinks.
Those skilled at preparing arena
iceare often in demand for major events where icequality is critical. The level of the sport of hockey in Canadahas led its icemakers to be particularly sought-after. One such team of professionals was responsible for placing a looniecoin under center ice at the 2002 Winter Olympicsin Salt Lake City, Utah; as both Canadian teams (men's and women's) won their respective hockey gold medals, the coin was christened "lucky" and is now in the possession of the Hockey Hall of Fame,Fact|date=February 2008 after having been retrieved from beneath the ice.
In speedskating, the official Olympic rink size is 30 x 60 meters for short track, and 400 meters for long track.
There are basically two rink sizes in use (as below), although there is a great deal of variation in the dimensions of actual
icerinks. Historically, earlier icerinks were smaller than today.
