Minecraft wiki entry for Making_nice_floors, associated text: The place where your smelting and managing food is done would look best with the tile-like floor, consisting of polished andesite and polished granite. Also, for a less subtle flooring, use the concrete pattern 1, with black and white concrete. If you have a separate kitchen and smelting room, use the tile-like floor for the kitchen, and for the smelting room, use (a) block(s) of your choice, or you could use the tile-like floor or black/white concrete floor for the smelting room as well.
