Celadon glazes have been investigated by means of an X-ray absorption spectrum (XAS) near a Fe-K edge by using synchrotron radiation and a Mössbauer spectrum. High-temperature treatments under CO-deoxidizing and oxidizing till about 1300 °C show the different glaze-color each other. The XAS analyses suggest that the deoxidized celadon glaze (Seiji A) and the oxidized one (Seiji C) have a modified α-Fe2O3 structure and an ideal one, respectively, but not FeO structure. The Mössbauer spectra also suggest that the celadon glaze-color depends on the hybridized 3d5L and 3d6L bands near an electronic Fermi level (EF), where the hybridization is induced by an electronic exchange interaction between 3d orbitals of Fe ions and 2p orbitals of surrounding O ions in the celadon glaze of glass-state.
