Ceramic tiles are made of clay and hold up well in high-traffic areas like kitchens. The surface of ceramic tiles can be either glossy or matte, and they come in a nearly infinite variety of colors and styles. Ceramic is durable because it is very hard, but that also has drawbacks. Ceramic tile is prone to chip or crack on impact. If you drop a dish or glass on the floor, it is likely to break. Toddlers may get more than the average share of bumps and bruises from falls on a ceramic floor, and it can be hard to stand on for long periods.
Porcelain tiles are even harder than ceramic and have many of the same qualities. But these tiles have color throughout, not just on the surface, so scratches, chips and cracks aren't as noticeable. They are more expensive.
