Abstract
A ceramic article is fired using a combination of microwave energy and conventional heating energy according to a microwave power-time heating schedule comprising a series of separate firing segments at predetermined microwave power settings, the core and surface temperatures of the article being monitored during firing to determine the core-surface temperature differential, that differential being controlled and limited to prevent cracking of the ceramic article by adjusting the level of applied conventional heat energy during firing.
