abstract = {A Raman spectroscopy study has been carried out with 633 and 768 nm laser lines to characterize three Cretan postage stamps. The first corresponds was issued by the Russian Empire Administration area and the other two belong to the 1905 Revolutionary Issues. The resulting Raman spectra are not of enough quality allowing a direct interpretation. Possible corrections to these spectra are, for example, the removal of the background fluorescence, the baseline correction and/or smooth. These tools are available in several spectroscopy software packages. The central question is the reliability of the spectra obtained after one or more corrections are applied. In order to begin creating a common procedure to treat all samples we ascribed only those bands that coincide with the cellulose calculated Raman frequencies. The first results suggest that it is necessary to carry out more studies with a significant number of samples before proposing a common treatment for all Raman spectra of postage stamps presenting fluorescence.},

abstract = {Raman spectroscopy was employed to study the non-printed area of a page of seven books printed in the 18th and 19th centuries. We employed the Vancouver Raman Algorithm to deal with the strong fluorescence background, obtaining spectra only in the 800 a 1800 cm-1 range. Two samples contain lignin, suggesting the presence of wood fibers. One sample (year 1799) contains only cellulose and gelatin. Two samples contain rosin. There are several Raman bands that we could not ascribe. Based on the results we propose a way to prepare the samples that could guarantee that the infrared and Raman spectra can be compared with confidence.},

abstract = {Raman spectroscopy pigments on decorated antique Chilean pottery belonging to the Diaguita's culture deposited in Museum of Limari, have been studied by using Raman spectroscopy. Four ceramic fragments from the unknown contexts were examined. Four colors were found with certainty: red, black, brown and white. Quartz and manganese (kempite) salts, as well as different types of oxide pigments: hematite, tenorite and possibly goethite, were identified.},
