Although both are manufactured in almost the same manner, there are some basic differences between ceramic and porcelain tiles. You can say that porcelain is a specialized form of ceramic tile, but the key difference is, that porcelain is slightly denser than ceramic, showing uniformity in color throughout the surface. On the other hand, ceramic tiles are easier to cut and shape and more affordable than porcelain. Ceramic tiles are also more flexible than porcelain. In order for a tile to be classified as porcelain, it should have less than a 1% water absorption rate.
