An ancient Egyptian gilded Cartonnage with polychrome decoration period to late -GreekRoman period found in Saqqara, Egypt was examined to characterize structure components (pigments, grounds layers and binder. It was studied by Optical Microscopy, X-ray diffraction (XRD), Laser-Induced Breakdown Spectroscopy (LIBS), Scanning electron microscopy coupled with energy dispersive X-ray (SEM-EDS) and Fourier transform infrared spectroscopy (FTIR) analysis. These techniques were used to identify the composition and morphology of grounds, nature of pigments and media used in the

“…Moreover, LIBS provides an in situ, rapid, and microdestructive approach for identification. [15,16] Previously our work identified wall paintings pigments with LIBS used multivariate treatments [17]. Other researchers have utilized LIBS to identify organic binders corresponding to different painting techniques.…”

The influence of ns-laser wavelength to discriminate ancient painting techniques such as are fresco, casein, animal glue, egg yolk and oil was investigated in this work.This study was carried out with a single shot laser on samples covered by a layer made of a mixture of the cinnabar pigment and different binders. Three wavelengths based on Nd: YAG laser were investigated (1064, 532 and 266 nm). The plasma is controlled at the same electron temperature after an adjustment of pulse energy for these three wavelengths on a fresco sample without organic binder. This approach allows to eliminate the effects of laser pulse energy and the material laser absorption.Afterwards, the emission spectra were compared to separate different techniques. The organic binding media has been separated based on the relative emission intensity of the present CN or C 2 rovibrational emissions. In order to test the capability of separating or identifying, the chemometric approach (PCA) was applied to the different matrix. The different solutions in term of wavelength range to optimise the identification was investigated. We focused on the evaluation for the laser wavelength to insure a better separation. The different capacity was interpreted by differentiating 1 Corresponding author.

Also, the electron temperature in the plasma was estimated, which provided the evidences to our findings.

“…LIBS technique has several attributes such as: i) no sample preparation required, ii) quick response, iii) nondestructive examination, vi) capability of remote detection using fiber optics, and v) multiple elements analysis simultaneously. These attributes make LIBS useful in many applications like online analyzing steel and slag composition, in situ detection of soil heavy-metal contamination [1,2], real-time monitoring material degradation in nuclear reactors [3], environment protection, artwork dating [4][5][6], and so on. Analytical control of the continuous casting of molten steel is significant for the quality control of products.…”
