Scientific report. Research on the composition of inks in a historical book by means of the X-ray fluorescence spectroscopy (XRF)

Computed tomography (CT) of a unique book from the National Library of the Czech Republic - Slavonic Library was performed in the TORATOM tomograph in Center Telč, Institute of Theoretical and Applied Mechanics, Czech Academy of Sciences. The book is a 17th century euchologion originating in Kiev. During the tomographic scanning, the possibility of measuring the composition of the inks used in the book was discussed. In general, there are parts printed in black and parts printed in red in the book. Therefore, the measurement described in this report was carried out, where several pages of the work were measured in the area of ​​black ink, red ink and in the area without ink
