This is actually a really cool topic. My 2nd year thermodynamics prof went on about this for half a lecture once, and offered to buy any student a coffee who wanted to talk about it outside of class.

So along these lines, we also know that ice that is "too cold" is also slower ice and is harder to glide on, and skates that are too sharp often have the same affect on gliding, as you cut deeper into the ice and increase the frictional coefficient.
But then what are the principles of synthetic 'ice' which has no ice to liquefy, and no pressure to speed up the melting? Couldn't this be another factor in the science of skating?
