| Abstract |
| The thesis work, conducted at the Laboratory of Chemical Physics, Department of Innovation Engineering, Lecce, aims to analyze through the use of analytical equipment three stamps: two dating back to the fascist period and one issued in 2000, to qualitatively evaluate the effects of time and oxidizing agents, and in order to show how the production and chemical composition of the stamps chenged over the years. For the analysis of stamps, has been used infrared spectroscopy in order to evaluate the differences in the production of paper and inks used for the manufacture of stamps in about sixty years. In particular, we have analyzed the stamps from different periods and series, two in the series bearing the image of king Vittorio Emanuele III and having the same economic value, and three other stamps belonging to the series Women in the Arts. |
