In this study, some results of previous studies concerning papyrus and paper, with special regard of artistic and archaeological materials, are reported and discussed. A historical introduction of such cellulose-based materials and of their use from the antiquity is presented first. The diagnostics and conservation aspects are discussed. The role of thermal analysis for a precise characterisation of these materials is illustrated. Complementary methods of investigation, such as optical microscopy, electron microscopy, X-ray diffraction and various types of spectroscopy are also considered. In addition, alteration or restoration processes may be usefully monitored by means of reflectance spectrophotometric measurements.

Abstract
In this study, some results of previous studies concerning papyrus and paper, with special regard of artistic and archaeological materials, are reported and discussed. A historical introduction of such cellulose-based materials and of their use from the antiquity is presented first. The diagnostics and conservation aspects are discussed. The role of thermal analysis for a precise characterisation of these materials is illustrated. Complementary methods of investigation, such as optical microscopy, electron microscopy, X-ray diffraction and various types of spectroscopy are also considered. In addition, alteration or restoration processes may be usefully monitored by means of reflectance spectrophotometric measurements.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
