Besides recreational ice skating, some of its uses include ice hockey, bandy, rink bandy, ringette, broomball, speed skating, figure skating, ice stock sport and curling as well as exhibitions, contests and ice shows. There are two types of rinks in prevalent use today: natural, where freezing occurs from cold ambient temperatures, and artificial (or mechanically frozen), where a coolant produces cold temperatures in the surface below the water, causing the water to freeze. There are also synthetic ice rinks where skating surfaces are made out of plastics. - Frank Joseph Zamboni , Jr. ( January 16 , 1901 -- July 27 , 1988 ) was an American inventor , whose most famous invention is the modern ice resurfacer , with his surname being registered as a trademark for these resurfacers .
