Abstract

Energy Dispersive X-Ray Diffractometry was used in combination with micro-RamanSpectroscopy to study an undated illuminated Iranian booklet. In both cases, no preliminarypreparation of the samples was needed: the data were acquired in a non-destructiveway in a natural environment. The book is of particular interest because of the unusualpresence of miniatures on some pages. The two techniques were used to collect data fromsmall areas of the pages and in different regions of the miniature in order to identify inksand pigments and to attempt chronological assignment. Raman spectra were affected bystrong background fluorescence. In spite of this, different peaks were detected and identified.Black and red inks were found to be cinnabar and carbon black, respectively.Spectra of pigments in the miniatures demonstrate the presence of rutile and calcite. Suchassignments were confirmed by the EDXD results which provided evidence for the presenceof titanium (rutile) and calcium (calcite). The presence of rutile suggested that theminiature may have been inserted later on the booklet preparation.
