Abstract
A method of firing a ceramic formed body, in which the ceramic formed body is fired by controlling a firing output state in such a manner that a high output state and a low output state are repeated reciprocally, is disclosed. In the method of firing a ceramic formed body, the improvement controls an opening angle of a burner defining the high output state, while a pulse output defining a reciprocal interval between the high output state and the low output state is maintained at constant.
