Both ceramic and porcelain tiles are made from clay, however porcelain tiles use a much denser clay with the addition of other raw materials, such as quartz. Not only is the mineral make up different, the manufacturing process also provides each with their own characteristics and qualities.
Porcelain tiles are fired at much higher temperatures and pressed at much greater pressures than ceramic tiles, reducing the voids and cavities in the tile making them less porous and increasing their strength and durability.
