Porcelain tile is similar to ceramic in that it is a clay base which is molded and then fired. The clay used in porcelain is typically denser, fired longer and at a higher temperature making porcelain more durable. Ceramic tile is known for its natural red terra-cotta color, while porcelain is usually grey or white. Porcelain is commonly left unglazed but can also be glazed. If the porcelain is left unglazed the color is consistent throughout. Therefore if the tile does get damaged or chipped it is far less noticeable. Porcelain can safely be used indoors or outdoors but check your specific tile rating to make sure it will hold up to the Midwest’s freezing and thawing. Porcelain can also be a good alternative to stone tile. With printing technologies advancing porcelain tile can mimic the look of natural stone really well. The tile variance scale for porcelain and ceramic tile is V1 – V4. V1 shade variation has little or no change from piece to piece and a V4 will have a large variety of color and/or texture changes.
