SUMMARIES
False Colour Infrared Photography (FCIR) is demonstrated to be an appropriate method for analysing iron gallotannate ink or its components (iron- or copper sulphate, tannin, gum arabic). Its advantage over other non-destructive optical methods (UV-light, Infrared spectroscopy, Proton Induced X-ray Emission) is that its apparatus is much simpler.
On a pu démontrer que la photographie infrarouge de fausse couleur (FCIR) est une méthode adaptée pour analyser l'encre gallique et ses composants (sulfate de fer ou de cuivre, tanin, gomme arabique). Son avantage par rapport aux autres méthodes optiques non destructrives (rayons ultra violets, spectroscopie infrarouge, émission de rayons X induite par des protons) est qu'elle nécessite un équipement beaucoup plus simple.
Es wird gezeigt, daß Falschfarben-Infratrotphotographie (FCIR) eine geeignete Methode zum Nachweis von Eisengallustinte bzw. seiner Komponenten (Eisen- bzw. Kupfersulfat, Tannin, Gummi Arabicum) ist. Gegenüber den anderen nichtmaterialzerstörenden optischen Methoden (UV-Fluorenzenz, Infrarotspektro- und -reflektographie, protoninduzierte Röntgenstrahlemission) hat sie den Vorteil des wesentlich einfacheren apparativen Aufwands.
