From hog's lard to high-tech refrigeration: the evolution of the modern ice rink

In short: Before modern refrigeration, early ice rinks were bizarre experiments using mixtures of hog's lard and salts to mimic frozen water. Today, these surfaces are feats of engineering, utilizing complex piping systems and precise thermal management to maintain perfect ice for everything from professional hockey to Olympic figure skating.

The term 'rink' originates from the Scottish word for 'course,' initially describing the surface used for curling. As skating grew in popularity during the 1800s, the name was adopted for constructed ice areas. Early attempts at artificial rinks in the 1840s were short-lived, as the 'smelly' lard-based substitutes failed to satisfy the public. It took until 1876 for British veterinarian John Gamgee to open the first mechanically frozen rink in London, using a system of copper pipes filled with a chilled solution of glycerine, ether, and nitrogen peroxide to freeze water.

Modern artificial rinks, or 'mechanically frozen' surfaces, rely on a bed of sand or concrete embedded with pipes that circulate chilled brine or refrigerant. This cooling process allows for a controlled, durable sheet of ice, typically built to a thickness of 19 to 38 mm. The surface is often painted white or blue to improve contrast for players and spectators, with markings for sports like hockey or curling applied before the final layers of water are frozen. Maintenance is critical, with specialized machines known as ice resurfacers—often called Zambonis—used to smooth the ice between sessions.

Rink dimensions vary significantly depending on the sport. While the International Skating Union prefers Olympic-sized rinks of 60 by 30 meters for figure skating, National Hockey League rinks are standardized at 26 by 61 meters, a size derived from the historic Victoria Skating Rink in Montreal. Beyond traditional arenas, specialized facilities like the Guidant John Rose Minnesota Oval provide massive outdoor refrigerated surfaces for sports like bandy. Whether indoor or outdoor, these facilities represent a sophisticated intersection of chemistry, engineering, and athletic tradition.
