Twenty five samples covering all the colours were taken from mural paintings at Maitepnimit Temple for study. Methods of the investigation involved the microscopical examination of the pigments and of the cross-sections of the samples. The inorganic pigments were analysed by microscopical chemical tests or by electron probe microanalysis with energy dispersive X-ray spectrometer and further identified by X-ray diffraction method with the help of Guinier-Hagg type focussing powder camera. The organic pigments were identified by thin-layer chromatography, high pressure liquid chromatography, and mass spectroscoру methods.
