The differences between ceramic and porcelain tiles include water absorption rate, durability and appearance. Porcelain tile is a form of ceramic tile and the two product´s main differences center on the way by which they are made.
Porcelain tiles are formed with pressure and heat, which makes them more durable than ceramic tiles. Ceramic tiles, on the other hand, are manufactured using a kiln-fired method, which makes them more porous. This increases their water-absorption rate, which makes them impractical for use outdoors or in areas of the home or office where they might be exposed to excess moisture.
Porcelain tiles look the same even when they are chipped, sanded or scraped. This is because their colors penetrate through the entire tile, so they can be refinished if they are broken. Conversely, ceramic tiles are not the same throughout in terms of appearance.
Porcelain tiles are best suited for high-traffic areas. They are not susceptible to frost damage or to excessive wear and tear, so they work well in busy kitchens, living areas and home entrances. Porcelain can also be glazed. Since glazes are categorized based on their scratch-resistance and durability, a higher grade of glazing is recommended for high-traffic areas.
