The stains caused by hand contact on the historical books are one of the problems in conservation of historical papers during the cleaning process. These stains are usually resistant and not easily soluble in solvents. Accordingly, it is necessary to know their structure in order to select the appropriate solvent and cleaning method. The aim of this article is to study the structure of stains caused by hand contact in historical papers. These stains are referred to as greasy stains in some texts, and many of them are old, and their abundance in some cases indicates the amount of object using. So this article tries to answer the question of what is the chemical structure of the hand-caused stains on historical papers. For this purpose, Fourier transform infrared spectroscopy (FTIR) was used to identify the structure of the stains in 20 samples of paper and paper works of Dariush Pebdeni in Foulad Shahr- Iran. Before the analysis, sizing material was identified by the classic methods. The results of this study showed that the structure of the stain is composed of sulfur proteins and does not have a fatty structure. Accordingly, a comparative study of the Fourier transformation infrared spectroscopy results of historical samples with animal proteins indicates the similarity of the spectrum of spots with the spectrum of animal glue and gelatin.
Keywords: Stain, Historical paper, Pebdeni Collection, Fourier transform infrared spectroscopy (FTIR).
