Mt. Romero et N. Ferrer, Fourier transform infrared spectroscopy applied to the characterisation of17th-20th century calcographic and xylographic inks, MIKROCH ACT, 131(3-4), 1999, pp. 237-245
The aim of this paper is to optimize the analytical method for the characte
risation of 17th-20th century calcographic and xylographic inks. It is very
important to use not only non destructive techniques, but also analytical
instruments that require a minimal amount of material so as to analyze uniq
ue or valuable samples. and simultaneously to obtain as much information as
possible about their composition. This study compares different ways of sa
mple preparation for further analysis by Fourier transform infrared spectro
scopy. It has been possible to analyze the most important absorptions that
appear in the spectra and therefore to associate them with the compounds co
ntained in inks. Some of the compounds identified are: hydro xyapatite (cal
cium phosphate), Prussian blue (ferric ferrocyanide), linseed oil, carbonat
es? nitrates and sulfates.
