The study here presented concerns the characterization, with chromatographic (high-performance liquid chromatography, HPLC) and spectroscopic (Raman spectroscopy and UV Vis spectroscopy) techniques, of red dyestuffs used to dye the yarns of ancient tapestries. Following the ancient recipes, the yarns (wool and silk) have been en dyed using natural red dyes such as madder, kermes and cochineal. By SEM EDX (scanning electron microscopy coupled with energy dispersive X-ray analysis) the yarns morphology has been investigated and the presence of the metals responsible for the specific mordants employed has been highlighted. The samples thus obtained have been studied in order to build a reference database that can be used later for the identification of the dyes used by the ancient tapestry manufacturers. Attention has been also paid to develop an n on destructive approach to be applied in situ.
