It is the liquid water that forms on its surface, especially under pressure, that makes it slippery. Ice at a low enough temperature is not slippery at all. What would make gallium slippery is the liquid metal caused by the pressure of the blades. Copper, iron, zinc, and lead do NOT melt under pressure, so they certainly could not make a rink that could be skated on. Gallium might, because of the rare property it shares with ice and a few other substances, although as I said, there are other considerations. | |

Unfortunately, it doesn't behave at all like water melting and it doesn't behave like ice at all. It isn't slippery. When frozen, gallium is pretty much like any other metal and you wouldn't want to skate on a rink made out of copper / iron / zinc / lead, etc. | |
