Porcelain tile is completely non-porous and is fired 1200° when being manufactured making the most durable option for any application. There are different kinds of porcelain edges, stamped and rectified. Rectified means the edge is a hard 90° which allows for smaller grout lines. Double-loaded porcelains are generally rectified but the line of where they’ve been compressed together is usually visible. In a thru-body porcelain the color and pattern on the surface of the tile spans the entire thickness of the tile. A thru-color is the background color remaining consistent all the way through the tile. Porcelain tiles can be used on floors, walls, and in most outdoor applications.
