Study of 19TH century inks from archives in Palazzo Ducale (Venice, Italy) using various analytical techniques

Inks and paper are the main materials and components of library and archive collections. Since the Third century B.C. there has been a continual succession of ink recipes from all over the world, with varying levels of documentation of the recipes used; however, it was only in the 19th century that Europe became the main producer and industrial leader in the discovery of new products. The aim of this study is to find out more about this last historical period, when new inks were created that had never been known or used in the past. in this study we chose four inks: they belong to documents preserved in the archive of the Superintendence Beni architettonici per il paesaggio e per il patrimonio storico artistico ed etnoantropologico (BAPPDAD) of Venice Lagoon, held in the Palazzo Ducale (Ducal Palace) of Venice. Fourier Transform Infrared Spectroscopy (ATR), Scanning Electron Microscopy (SEM-EDS) and pyrolysis coupled to a gas chromatograph with mass spectrometric detector (Py-GC-MS) allowed us to obtain a qualitative characterization of organic and inorganic elements in three different ink typologies.
