<P>PROBLEM TO BE SOLVED: To provide a firing tool that has small compositional fluctuation of the surface and small characteristic dispersion, and is capable of obtaining a smooth porcelain. <P>SOLUTION: The firing tool is comprised of a supporting plate that can place a molding body thereon, a spacer that is installed so as to surround the molding body on the supporting plate, a top plate installed on the spacer and a heavy material that is placed on the molding body. It is possible that a closed space is formed by combining the supporting plate, the spacer and the top plate. Each of the main face of the supporting plate, the main face of the spacer being directly in contact with the main face of the supporting plate, the main face of the top plate and the main face of the spacer being directly in contact with the main face of the top plate has a surface roughness Ra of 3μm or less and a planarity of 20 μm or less. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
