By adding lithium carbonate to the raster basket, the entire surface of the ceramic product can be reliably and vividly given iris and metallic luster. More preferably, the amount of lithium carbonate added is preferably 0.5 to 3.0 parts by weight with respect to 100.0 parts by weight of the basic glaze. This is because the addition of lithium carbonate within this range exhibits the most remarkable effect. Furthermore, it is preferable to add at least one of titanium oxide, manganese oxide, cobalt oxide, copper oxide, molybdenum disulfide, or ferric oxide as a colorant to the raster soot of the present invention, whereby various colors are added. In addition, various ceramic products exhibiting color tone and exhibiting iris and metallic luster on the entire surface can be produced.
