For analysing color of lime glaze containing 1 mass% or 8 mass% of Fe_2O_3, the spectral absorption coefficients were measured by a method based on Kubelka-Munk theory. The strong absorption considered as a tail of absorption in ultraviolet region was shown at the short wave length side on the glaze containing 1 mass% of Fe_2O_3. The coefficients of the absorption increased largely with increasing Al_2O_3 content in glaze. But the absorption coefficients were almost independent with SiO_2. The spectral absorption coefficients of 8 mass% Fe_2O_3 were similar to the tendency of the glaze with 1 mass% Fe_2O_3. From the results obtained in the present work, the correction of the traditional admitted explanation, the variation of apparent color in the iron glaze is entirely explained by the variation of absorption in visible region, should be neccessary. An influence of factors other than absorption should be investigated on the variation of color.
