Abstract
In the process for firing green moldings of ceramic pastes which contain plasticizers, the green moldings are placed on kiln furniture which has at least a temperature which corresponds to the decomposition temperature of the plasticizers. In addition, the kiln furniture and the green moldings are heated within 5 to 60 minutes to the firing temperature and kept there for 5 to 60 minutes. Cooling is then carried out to the original temperature within 5 to 60 minutes and the moldings are removed from the kiln furniture at this temperature. The invention achieves heating cycles of less than 3 hours.
