What are the main differences between porcelain and ceramic tiles?

Often difficult to tell apart, ceramic and porcelain tiles are made with very similar materials and processes, but there are slight differences between the two types. In general, 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.Porcelain tile is harder than ceramic.Although both are made from clay and other naturally occurring materials fired in a kiln, the clay used to make porcelain tile is more refined and purified. It’s fired at a higher temperature and greater pressure, resulting in an extremely dense and hard material.
