The stucco busts of Muhammed Ali family had not received any adequate researches concerning the methods of implementation and conservation. Thus, this research will try to shed more light on them through studying three stucco busts kept in Prince Mohammed Ali's Museum in El Manial by USB digital microscope, photographing under UV light, X-ray diffraction, the Fourier transform infrared, and scanning electron microscopy-energy dispersive X-ray analysis. The physicochemical study of the three

Zincite was used as a pigment in the white painting layer of Khedive Ismail stucco bust. The detection of greenalite, zincite, and barite testifies the whitish green painting layer of Khedive Tawfiq stucco bust. At the same time, the occurrence of hematite in Khedive Ismail stucco bust testifies the effect of iron nails corrosion. The Fourier transform infrared results indicate that the used organic media of pigments is glue.
