The painting materials in the Islamic monuments in Cairo were variable and distinguished. The accurate identification and characterization of painting materials in an art object or in a paint layer is certainly an important step in the history of art, technology and conservation. The main objective of the present paper is to examine and investigate the different painting materials (pigments, gilding, binding media and painting ground) employed in the decorated ceilings of Madrasa of Al-Ashraf Bersbay (Mamluk Jarkasy period). X-ray diffraction (X.R.D.), scanning electron microscope SEM (EDAX), light optical microscope (LOM) and fourier transform infrared spectroscopy (FTIR), together with determination of physical properties of the support (water content and density) and microbiological study, adapted for analysis, investigation and evaluation of the current status. The study revealed the severe damage of painting materials. Gypsum, ultramarine, smalt, prussian blue, red ochre, emerald green, red lead (minium) and gold leaves were identified in El-Ashraf Bersbay Madrasa decoration painting. [ABSTRACT FROM AUTHOR]

The decorated ceilings in the Islamic monuments in Cairo decorated with different kinds of pigments. The main objective of this study is to analyze and investigate the decorative materials (Decorative Materials pigments and gilding & painting ground ) on the ceilings of Madrasa of Al-Ashraf Bersbay ( 826 A.H & 1423 A.D Mamluk Jarkasy period ), for determination the accurate components of these materials which unfortunately, often much less is known about its composition. X- Ray Diffraction (X.R.D.) Scanning electron microscope S.E.M (EDAX) Light Optical microscope (L.O.M.) and Fourier transform infrared spectroscopy (FTIR), together with determination of Physical properties of wood ( water content and density ) and Microbiological study, adapted for analysis investigation and evaluation the status.

The present paper is a result of investigation on migration of some consolidates - Thermoplastic resins to the surface pores of impregnated stone which are reported. The causes of migration were evaluated as well as the conditions which allow reducing these undesirable effects. It has been stated that the effect of resin molecules, solution viscosity, stone structure and the conditions of drying after impregnation. This investigation are applied on lime stone samples as a porous stone which widely used as building materials in Egypt. Different analytical and investigation methods were applied to study the stone samples such as polarizing microscope, X-ray diffraction analysis (XRD) and scanning electron microscope (SEM) equipped with (EDX) microanalyzer.
