Hockey and speed skates, on the other hand, have evolved more rapidly in recent years. Hockey skates have gained mobility in the ankle, and speed skating clap skates with hinged boots allow racers to keep their blades on the ice for longer periods of time and reach higher accelerations.
Bone skates—generally made from the shin bones of cattle and horses—have been found throughout particularly flat and wet regions of Hungary, Scandinavia, Germany and elsewhere.
He should know: He once made a pair himself in an effort to understand the Bronze Age experience. He then defleshed and cleaned these bones, used a modern drill to make holes in the front and back, and attached leather straps that secured the bones to his boots. Finally, he gave them a try. Whereas modern skates with blades travel only forward and backward, bone skates lie flat and can glide in all directions.
But records and paintings from the 14th and 15th centuries showing adults and kids scurrying on the ice suggest that leisure has long been at least one component of skating. People sell hot wine and sausages on the ice. Touring skates or Nordic skates are long blades that can be attached to hiking or cross-country ski boots and are used for tour skating or long distance skating on natural ice. Skates provide mainly fun and entertainment in the winter time.
There are a number of sports that are played on ice skates including ice hockey, speed skating, and figure skating. These are some of the most popular sports in the Winter Olympics.
In order to make skates with a metal blade, people first had to have the ability to smelt purify and work metals like iron. Rigid shoes also make for better skates.

And this all happens in an instant. Again, all this would be a very hard thing to see firsthand in an experiment. So it stands as a hypothesis for now. Even though there would still be a tiny liquid layer on the ice, it would take too much friction to generate enough heat to melt anything else. Also, below this temperature, the tiny liquid layer on top of ice becomes harder and harder to detect. It would be like skating on gravel. Case closed.
But I was left wondering: Are there any other surfaces we could skate on? Mercury freezes at It would take far too much energy to keep a rink of mercury that cold. Plus, mercury is a potent neurotoxin.
What about gallium? But just imagine skaters doing triple axels on a silvery mirror gallium surface. When aluminum interacts with gallium it becomes very brittle. Though solid gallium would be more slippery near its melting point, would it be slippery enough for ice skating? Or easy enough to plow through? Our mission has never been more vital than it is in this moment: to empower through understanding.

Unless you can prove otherwise I think it is unwise to cite that wikipedia entry as a source. It was also cited with a source in the misconceptions I don't currently have access to the source.
Unless you can provide some good proof of this, you are going against the other things said and the purpose of this thread. The point being that the burden is on you to prove this pressure is enough for the stated effects. Many sources don't believe it is a good enough explanation. But when that pressure is removed,water again coverts into ice. Don't you this this is what happens while skating? The issue isn't that regulation isn't a thing.
The issue is that quantitative analysis of the situation shows that the effect isn't great enough to even cause localized melting. You would need pressures you wont achieve by skating on ice, so additional factors are required to describe the phenomenon.
