- 1. A setter used for firing a ceramic honeycomb structural body, comprising a honeycomb structural ceramic plate having a top surface and a bottom surface, longitudinal flow cells passing through said plate in a perpendicular direction to the surfaces, and a bevelled portion at an outer peripheral edge portion of said top surface, wherein said top surface contacts a substantial portion of an end face of the honeycomb structural body.
- 4. A process for firing a green honeycomb structural body by using a setter, wherein the setter is made of a honeycomb structural ceramic plate having a top surface, a bottom surface, longitudinal flow cells passing through said plate in a perpendicular direction to the surface, and a bevelled portion at an outer peripheral edge portion of said top surface, said green honeycomb structural body being fired on the setter while an outer peripheral edge of said top surface contacts an end face of the green honeycomb structural body at a portion of said end face which is inwardly spaced from an outer peripheral surface of said body by a distance of at least 3.0 mm.
- 9. A process for firing a green ceramic honeycomb structural body by using setters, comprising firing the body while the setters are brought into contact with opposite open end faces of the green honeycomb structural body, wherein said setters comprise at least one bevelled ceramic honeycomb structural setter.
