Porcelain tile is versatile and can be used both indoors and out. It's dense and hard, so it stands up well to heavy traffic. Quarry tile provides natural good looks while offering excellent traction. Terra cotta, also called Saltillo, tiles may be either handcrafted or machine made and provide a unique, old-world look.
Ceramic tile is composed of clay, minerals and water, which are pressed together and then fired at high temperatures until they solidify. It may be glazed or unglazed. Glazed ceramic tile features a liquid glass coating that helps tile resist stains, scratches and fire while protecting it from fading and making it easier to clean. Unglazed tiles have no coating and possess an even color all the way through, making them ideal for high-traffic areas.
The color and thickness of the grout is the most important part of a tile floor. The grout should enhance the tile and blend in with the home décor at the same time. There are many standard grout colors, as seen in the chart, yet a custom color can always be made.
