Ceramic Tile Types - The architects in our area throw around the terms "ceramic," "porcelain," and "quarry" tile, and I'm not sure what the differences are?
ANSWER ANSWER -
Porcelain and quarry tile are part of the family of ceramic tiles, which are clay based materials. Porcelain is a more refined and dense type of ceramic tile. Quarry tile is an extruded type of ceramic tile that is less dense and more absorbing than porcelain tile, but it is still a commercially rated tile for floors. Of course not all porcelain tiles are created equal nor are all quarry tiles equal. The quality varies depending on the manufacturer and the process used to make it. There are also other types of ceramic tile.
