Most types of tiles that are made from a form of clay or a clay mixture, which are then kiln-fired, are considered to be a part of the larger classification of tile called ceramic.

Porcelain tiles are generally made by pressing porcelain clays, which results in a tile that’s dense, impervious, fine grained, and smooth with a sharply formed face. Porcelain tiles usually have a much lower water absorption rate than ceramic tiles, making them more frost resistant, although not frost proof. Glazed porcelain tiles are much harder and have more wear- and damage-resistance than ceramic tiles, making them suitable for any residential and light commercial application.
