Possibility of classification manufacturing time by colors and chemical compositions of the glaze in the Choson blue and white porcelains has been investigated. The specimens are the 15th and 18th centuries excavated from the kiln sites in the Choson dynasty. The color of blue pigment layers is measured by a spectrophotometer. The metallic elements of blue pigment layers are obtained with an wave length dispersive X-ray spectrometer. The color of glaze in the Choson blue and white porcelains shows the absorband of 500∼650 nm and this is a attributed to Co2+ ions. The peaks of absorption are approximately 520, 592 and 640 nm. In the dominant wavelength (λd)of colors, the 15th century samples tends to situate longer wavelength area than that of 18th century samples. The border is 476∼477 nm excitation purity (Pe) of the 15th century samples is relative higher than that of 18th century samples. In the glass components in glaze, SiO2 and CaO concentration of the 15th century samples are higher than that of the 18th century samples. The concentration of Al2O3 and K2O of the 18th century sample is higher. The amount of main staining CoO, in the 18th century sample is twice as much as the 15th century samples. On the transition elements, the relative concentrations of Fe, Ni, and Cu of the 15th century samples are high, and the 18th century samples shows high relative content of Mn.
