Ceramic tile is the most common type of tile, and it’s a broad category that includes many subsets of tile. It is made from a solution of clay minerals and water, then pressed into a tile shape and fired in a kiln.
Often ceramic tile has two layers: the bisque, or body of the tile, and the glaze, which is the top layer that includes the tile color and pattern. Some ceramic tiles don’t have a glaze, and they have a solid color throughout. This is called a through-tile construction, and these tiles are typically the natural red or brown on unglazed ceramic.
Ceramic tile is durable, and waterproof when glazed, but it’s porous enough to be susceptible to chipping, and it’s not suitable for outdoor use.
