according to the WFCA, Porcelain tiles are made up of a sand like material. These tiles are formed with pressure and heat to become stronger, more dense, and absorb less water than regular ceramic tiles.
Because of the moisture absorption rate (.5% or less), most porcelain tiles can be installed outside or inside.
Since the Porcelain tiles have a through-body-color, they usually will not need to be replaced if chipped.
In the beginning, ceramic tiles were made by hand. Wet clay was shaped, sometimes with a wooden mold, then left to dry in the sun or fired in a small brick kiln. While some artisans still craft ceramic tiles by hand, most ceramic tile now a days are made through a process called "dry pressing" or "dust pressing."
Ceramic tiles are made from clay, minerals, and water. The materials are fired and glazed because traditional ceramic is porous. During this process color and looks are added.
Ceramic is much easier to installed than Porcelain.
There are three basic types of rock from which we carve out stones for floors: Travertine and limestone are examples of sedentary stone. Granite is an example of Igneous stone. Slate and Marble are examples of metamorphic stone.
Stone floors offer the history no other floor covering can. Since early, civilizations used natural stone for their most important works. Temples, monuments, government buildings, homes, and even roadways.
