CERAMIC

Mosaic-tile floors that have been excavated in Piazza Armerina, sicily, are 1,800 years old.  How's that for durability?

The Porcelain Enamel Institute groups tiles in categories (I to IV+), indicating increasing durability. Durability is a function of a tile's hardness, and of the sheen and color of any glaze.  (Light-color glazes are more durable than dark, for example.)  Kitchens usually need a group III or higher tile.  Choose a tile with a good slip resistance.  Unglazed tiles are less slippery than glazed tiles.  Any tile with a slightly textured surface provides greater traction than a smooth tile.  The texture shows dirt less; too much texture, however, inhibits cleaning.

Tiles that mimic stone in their texture and have mottled coloration are popular now.  Many of these tiles are porcelain products, fired at temperatures so high that they are vitreous.  This process renders them harder than the slate, granite, marble or limestone they resemble.  They are extremely dense and absorb little water, meaning you can continue your flooring outside the house.  And these tiles are made in sizes larger than previous standards, up to 18 in. sq. 

PROS - Durability and hardness, enormous variety, simple care, environmentally friendly, no staining or fading, good over radiant heat, moderate cost.

CONS - Less comfortable underfoot, hardness means breakage of dropped items, cold, noisy, grout can stain or crack.
