Hydrofluorocarbons, or HFCs, are used to keep long stretches of ice, like the ones in arenas and skating rinks, cold for long periods of time. HFCs are human-made greenhouse gasses that absorb heat and are used to do things such as keep your refrigerator cold. But these refrigerants pose environmental problems.
Do they use real ice in the Olympics?
Figure skating and short track speed skating use the same ice rinks, though the actual ice surfaces used are very different. For short track speed skating, the ice is usually between 3.5 and 4.5 cm thick. When the same ice rink is used for figure skating, the ice surface will be a little thicker at 4.5 to 5 cm thick.
What is NHL ice made of?
At the beginning of the hockey season, the arena uses an advanced refrigeration system that pumps freezing "brinewater" (salt water) through a system of pipes that run through a large piece of concrete known as the "ice slab." When the "ice slab" gets cold enough, layers of water are applied to it.

Short track speed skating ice requires a thickness of 1 to 1.25 inches (2.5–3cm), compared to figure skating where the ice is 1.5 to 2 inches (3.8–5cm) thick.

What does a Zamboni cost?
As the sizes and options of the Zamboni machines vary greatly according to each ice arena's individual needs, so does the price. The Model 100 (a small tractor pulled unit) may be in the neighborhood of $10,000.00 or more and the full-sized machines can be up to or in the low six figures.
Why is Salt Lake city ice so fast?
Records set at the Utah Olympic Oval

Do they Zamboni during figure skating?

Beyond the complex refrigeration systems, Zambonis are the primary tool in making the ice and keeping it in good condition, a big machine that does a lot of detail work.
Why do female skaters retire so early?
