How can you tell the difference between porcelain and ceramic?

The main difference between a porcelain and ceramic tile is the rate of water they absorb. Porcelain tiles absorb less than 0.5% of water whilst ceramic and other non-porcelain tiles will absorb more. This is down to the stuff used to make porcelain tiles. The clay is denser and so less porous.
