Symptoms include lavalike coating solidly connected with the bricks, and falling coating which will take off the densified brick heads. This phenomenon is caused by the formation of an increased liquid clinker phase infiltrating the hot face. EXCESSIVE THERMAL LOAD generally occurs during overheating above 1700° C without a liquid phase.
