The automatic inspection by the image processing device was possible. However, the addition amount is 0.
When it exceeds 5% by weight, the coloring component becomes a foreign substance and pinholes of 10 μm or more are generated on the surface of the glaze layer. Therefore, the amount of cobalt oxide or cobalt simple substance added is preferably 0.1 to 0.5% by weight. The center line average roughness (Ra) of the glaze layer surface of the glaze ceramic substrate of the example of the present invention was 0.02 μm, which was extremely smooth.
