The polychrome ceramic relics own abundant information which play an important role in studying ancient Chinese history, culture, economy, science and technology. Because the polychrome ceramic relics analysis couldn't be satisfied by common analytical methods, various kinds of nondestructive spectral technology have been introduced in this area gradually. This paper presented the theory, feature and limitation of the nondestructive spectral technology such as Laser Raman microscopic spectrum, laser induced breakdown spectra, and EDXRF from three parts: pigment analysis, ceramic analysis and relic information identification. Finally, the future development trends were discussed.
