Abstract
The spectral absorption and scattering coefficients obtained on the basis of the Kubelka-Munk theory are useful for analyzing the color of glaze. The relationship between the color of lime glaze containing chromium or iron and its chemical composition was examined by measuring these coefficients. The apparent color of glaze was significantly influenced by the scattering coefficient. Complicated changes in the apparent color of glaze were explained by the occurence of several elemental changes in the absorption and scattering coefficients. In this method, these coefficients were obtained by measuring visible spectral reflectance and transmittance of thin section of glaze. There is a slight difference between the color estimated from these coefficients and actual color of glaze testpiece. The relationship between these coefficients and apparent color of glaze is studied.
