Please take note of the parallelogram shape. This unique visual presentation offers an eye catching pattern possibility that can clearly set the Waterfall Collection apart from more mundane product offerings.Porcelain tile may be described or imagined in many different ways. However, in general, the body is typically composed of kaolin clay feldspar and quartz. Although in recent years this composition has evolved. It is pressed into its shape and originally was left unglazed. In current times various glazes or pressings can then be added to the process. This shape is then fired at extremely high temperatures in a kiln which is essentially an oven. The result is a very dense of vitrified material with almost no water absorption.
