Through body porcelain is an extremely durable tile great for high traffic commercial areas, such as shopping malls and airports. Through body porcelain is usually unglazed and able to take a polish. The porcelain is formed with the paint mixture already added which makes the color of the porcelain runs all the way through the tile, making chipping, scratches and dings less noticeable. Through body porcelain has a smooth color and often has very little texture, making it smooth to the touch. Extremely smooth tile can be slippery, so it is best to choose a textured tile when doing floor installations or to apply an anti-slip solution, such as Invisa-Tread.
