Abstract

The painting support was manufactured from two distinct layers of which the thick underlayer was made of papier mâché and the thin upper layer was a finer layer of fibres. The support comprises cotton fibres with some additions such as kaolin (Al2O3·2SiO2·2H2O) and gypsum (CaSO4) as revealed in FTIR analysis. Hair and straw enclosures were also added to the pulp to strengthen the support. Two pigmented preparation layers were applied, of which the main layer is a blue formed from indigo pigment. The other, a red preparation layer, was applied on the margins of the painting. The pigment palette, as revealed by Raman microscopy, is quite simple and comprises; Lapis lazuli, indigo as the blue pigments, orpiment as the orange pigment, and red lead as the red pigment. The FTIR spectra for the lacquer layer suggested the application of shellac resin admixed with linseed oil. The highly needed conservation treatment was carried out. It included cleaning with saliva and Isopropyl alcohol, securing the detached paint layer and splitting paper sheets with klucel G 4%, Deacidification of the verso of the painting with calcium hydroxide, retouching using acrylic paints and varnishing with paraloid B-72 in toluene. Finally, a museum-grade display box was created and labelled with the painting's documented information
