Why do skates glide easily on the ice, but on glass, where the surface is smoother, is it impossible to skate on skates?

It should be understood that when skating on ice, the following process occurs:

1. In the movement of the blade due to the forces of friction on the ice, the temperature increases at the point of contact of the metal with ice.

2. Due to the rise in temperature, a thin layer of water is formed when ice melts at the point of contact.

It is due to the thin layer of water that the blade slides on the ice, since water plays the role of a lubricant. When the metal blade of the skate contacts the glass, no lubricant similar to water is released, the friction force is still great and sliding does not occur.
