Tiling has been around for a long time, dating back as early as 4700 BC. It's definitely not new to home décor, but it’s grown tremendously in style options and application. With digital glazing, the styles of tile are almost endless, anything from natural stone to hardwood or even custom patterns. Besides styles and colors, common options when picking tile are ceramic or porcelain. What's the difference?
The materials that make up ceramic and porcelain are basically the same. Both are commonly made from clay, sand, and a mineral called feldspar. Once those materials are in the right consistency, they go on to be extruded or pressed, digitally glazed, and then fired in a kiln to solidify the finished form. Within this process is where porcelain differs. The clay used is more refined and purified. It's fired at a higher temperature and greater pressure, resulting in a denser, harder material than ceramic.
No tile is waterproof, but because of porcelain being harder and denser than ceramic, it absorbs less water. Most true porcelains have a 0.5% moisture absorption rate. Ceramic tile’s moisture absorption rate can be anywhere between 3% to 7%. Because of this difference, ceramic can’t be used as an outdoor tile like porcelain can.
All in all, porcelain is stronger and better protected from moisture, so it may be a better option for your home. Take into consideration the traffic levels and exposure to moisture your floor will encounter before making your final decision.
