To control ceramic drying and calcining operations, an approach that ensures uniform gas evolution was developed to prevent cracking on sudden release of gas. Instead of increasing temperature according to a preset schedule, the output signal from a thermogravimetric analysis apparatus is used as input to a computer system which varies temperature as required to cause mass loss to follow a preselected schedule. Materials that cracked when processed conventionally were prepared crack‐free by this procedure.
