The Taidong Tomb in the imperial tombs of the Qing dynasties has great aesthetic value and a rich history. In this study, we conducted the first investigation ever performed on the raw materials used in the paintings in the Taidong Tomb. Energy dispersive X-ray spectroscopy (EDX), polarized light microscopy (PLM), X-ray diffraction (XRD), micro-Raman spectroscopy (m-RS), Fourier-transform infrared spectroscopy (FTIR) and pyrolysis-gas chromatography-mass spectrometry (Py-GC/MS) were used to comprehensively analyze the painting of Long'en Hall, Xipei Hall and the ceiling of Minglou. In the conclusion of the study, the paintings were found to contain natural mineral and synthetic pigments, including atacamite (Cu2Cl(OH)(3)), azurite (2CuCO(3)center dot Cu(OH)(2)), vermilion (HgS), carbon black (C), anglesite (PbSO4), white lead (2PbCO(3)center dot Pb(OH)(2)), synthetic emerald green (Cu(CH3COO)(2)center dot 3Cu(AsO2)(2)) and ultramarine ((Na,Ca)(8)(AlSiO4)(6)(SO4,S,Cl)(2)). This allows us to conclude that some of the architectural paintings were repainted in the mid-to-late 19th century. The mortar layer may consist of brick ash (albite, gismondine), lime water, tung oil and flour. The fiber layer material may be ramie. Researching the raw materials of the paintings in the Taidong Tomb is of great value because it provides scientific data for the future preservation of the paintings in the tomb.
