Generally porcelain tile does cost much more than your average ceramic tile.
Porcelain is made from finely ground sand and clay. Like ceramic, porcelain tiles are available glazed and un-glazed and come in a vast array of color, style and texture however they are typically more durable and refined than ceramic tiles which is therefore reflected in the price.
Durability & Strength of porcelain tiles
When creating a porcelain tile, temperature and strength become synonymous. The higher the temperature in which a porcelain tile is fired the stronger it will become. Although both ceramic tile and porcelain tile are created in kilns at extreme heat, porcelain tiles are fired at a higher temperature resulting in a stronger product.
Scratch resistance - Extremely resistant to scratching and deeper abrasions. Glazed porcelain is also very stain resistant.
Strength - Porcelain tile is stronger than most stone products on the market and is unaffected by UV rays. It will not create static electricity and will stand up to almost any chemical agent.
Fire resistance- Porcelain tile will not burn and does not produce toxic fumes.
Water resistance- Porcelain tile is far more resistant to water than ceramic tile. The absorption rate for porcelain tiles is 0.5% and even less.
Maintenance - Glazed porcelain tile maintenance is as simple as a quick sweep and a mop when necessary, however if your choice of tile is natural or polished porcelain, be sure that your floor is properly sealed otherwise cleaning could get more difficult!
