PURPOSE:To simplify the separation of a setter after burning a ceramic compact formed into a bottomed cylindrical shape, prevent a material to be burned from being damaged and improve the yield. CONSTITUTION:A ceramic compact 1 formed into a bottomed cylindrical shape with an opened lateral end (1a) downward is placed on a setter 2 and burned. The setter 2 is provided with a through hole 3 for allowing a gas to flow into an inner space (1b) of the material 1 to be burned. Since the pressure of the inner space (1b) of the material 1 to be burned is not lowered from that of the outside with the through hole 3 even if the burnt material 1 is taken out in a state of the setter 2 sticking thereto after the burning, the separation of the setter is simplified so much. |
