Porcelain tile and ceramic tile both start off the same being composed of more or less the same materials such as clay and quartz. After formation they are both fired to high temperatures.

This is an extremely important difference since being more dense means that porcelain tile absorbs far less moisture making it both durable and stain resistant.
