You need the surface of the ice rink to melt though in order to "skate".

You're going to have to explain this we well. I've skated perfectly fine at -40, and there was no melting going on.

When there's melting going on at the rink, we're not allowed on the ice.

The melting is just at the interface between the skate and the ice. (It re-freezes after.)

I don't see how this stronger ice would operate any different than regular ice.
