CHINA CLAY - A RAW MATERIAL FOR EVERYDAY PRODUCTS

A special form of calcination is the so-called "flash calcination". In this process china clay is heated up very quickly. Within the china clay platelets small voids and edges are formed where air bubbles can settle. The resulting higher opacity does not only provide higher opacity in the dry film but also in wet film. ...
