The playing area is called a "sheet" of ice, so a curling club with 4 playing areas is said to have 4 sheets. The actual ice surface is different than normal hockey/figure skating ice in that it has tiny bumps all over, called the "pebble," that reduce the friction between the ice and the 42 lb granite stones.

Curling is played on a long, narrow sheet of ice. The ice is significantly different from "normal" ice-skating or hockey ice, however. The surface of the ice is covered in "pebble," tiny bumps that are created by spraying hot water droplets on the ice. The pebble allows the curling rocks to slide more easily, makes the behavior of the rocks more predictable, and creates places for debris to hide. The ice is pebbled before each game (because the pebble wears down during play), and after a few games a scraping tool is used to scrape off the old built-up pebble and provide a new surface.
