Is terracotta tile durable?

Yes. There are examples of terracotta floors that have been in place for hundreds of years. Today, proper installation should ensure long product life. What is the difference between terracotta and ceramic? 

Both product categories start as clay and are then fired. The clay used to make terracotta contains more impurities and is fired at a lower temperature than the clay used to produce ceramic. The clay impurities result in the reddish-brown color values associated with terracotta. Consumers and professionals alike think of terracotta as an unglazed reddish-brown tile. Ceramic tiles are usually thought of as having a glaze of some color that was fired over a red or white tile body.
