Porcelain and ceramic tile flooring are not the same product, there are differences. Similar ingredients are used in the manufacture of both ceramic and porcelain tile. Becoming familiar with their differences is helpful in choosing tile for a project that is the right price, looks good, and has the durability needed for the area of installation.
Red or white clay, mixed with minerals and water are used in ceramic tile manufacturing. The tile is baked in a type of kiln. A glaze to reduce the natural porosity of ceramic tile is nearly always applied.
Fine grain, light-colored clays, feldspar, quartz, and a minimal amount of water are used to make porcelain tile. The combination is extruded or pressed before it is fired at temperatures that are significantly higher than those employed in the manufacture of ceramic tile. Porcelain tile is available in both glazed and unglazed versions.
