Sažetak
Croatia has possessed books continuously since the Middle Age. One of the most beautiful examples of the 16th century Prandau-Normann collection is the description of the military campaign of the Portuguese king Manuel I − Hieronymi Osorii Lvsitani Silvensis in Algarbiis episcope, printed in the printing house of Arnold Birckmann, one of the three most famous Middle Age printers in Köln. Experimental work showed that a pigment palette is a common one for the period between 16th and 19th century. Three complementary, non-invasive spectroscopic techniques were used: micro-Raman spectroscopy, PIXE spectroscopy and UV-VIS FORS spectroscopy. Several pigments were identified, like vermilion and minium, white lead and massicot. However, pigments from blue, light blue and green coloured regions could not be determined uniquely, leaving the authors’ palette incomplete. Fluorescence, coming from the usage of the Ar+ laser, was the main negative factor during the Raman experiments. For some of the pigments, it was so intense that it covered all of the pigments spectral lines. Dr. Theodore Ganetsos, during his visit in Croatia, used a portable Raman Spectrometer (laser 785nm), which would not induce such fluorescence and, consequently, more Raman lines are presented, making the pigment identification more definite and authors’ palette complete.
