CARACTERIZAREA CU APARATURĂ SPECTRALĂ A SUPORTULUI PAPETAR AL MANUSCRISELOR ÎN PROCESUL DE CONSERVARE SI RESTAURARE
THE EXAMINATION OF MANUSCRIPTS’ PAPER WITH SPECTRAL DEVICE IN THE PROCESS OF CONSERVATION AND RESTORATION

Summary/Abstract: The authors intended and realized a non-destructive device that measures spectral parameters of old paper. Finding out the optical characteristics of old books or works of art’s paper helps both the identification of their origin, their dating, as well as the proper selection of materials necessary for conservation and restoration. The device uses non-destructive optical methods based on the spectrometry of reflectivity which represent the investigation of the spectral composition of an optical radiation reflected by a surface. The tests of the apparatus were made on a Romanian manuscript from the eighteenth century, in the National Center of Conservation and Restoration of Old Book, from the National Museum of Unification Alba Iulia. Following the results of the experiments the authors can conclude that the device is very useful in the process of conservation and restoration of the old manuscripts and can be used for finding out the color parameters.
