In this text, the representations of the main machinery necessary for the process of manufacturing materials of burnt clay are virtual reality images of old equipment, but the principles are still applicable now because today’s manufacturing methods and processes are the same as those used in the past; even though the enormous progress made and the advanced techniques developed have allowed increasingly sophisticated materials to be designed, research has in fact been focused on working with the different clays, from the point of view of preparation, drying or firing. In actual fact, it is the better knowledge of the properties of clays that has made it possible for a burnt clay industry to develop.
