(Also see Ceramic Wall Tile, Glossy Wall Tile and Porcelain)
Ceramic tile is made from clay. A glaze is applied to the top surface and then the tile is fired at a high temperature. The glaze creates the color and pattern of the tile. The durability of the glaze on ceramic tile can vary greatly. Check the PEI rating of the tile for glaze durability.
Ceramic tile is generally quite porous and therefore is generally not recommended in exterior freeze/thaw zones.
