Abstract

Cleaning of paperwork and documents is one of the main steps in protecting and restoring of cultural properties. Considering the fact that the stains generated by hand contact due to numerous pages turning of books on the surface of the paper, the appearance and aesthetics of the book pages are distorted. It also chemically degrades cellulose fiber. Therefore, removing such stains is important in the process of protecting paper documents. Different chemical materials and methods are used to remove various stains on paper, including organic solvents which are flammable and toxic. Therefore, the use of some methods and materials for paperwork, as well as the health of restorers and even the environment, are hazardous. This research evaluates the Enzruth gum extract at different concentrations for removing stains generated due to hand contact, based on the advice of ancient texts, . Maceration (soaking) method was used to extract gum. Fourier transform infrared spectroscopy was used to evaluate the historical samples and colorimetric, pH-meter methods, macroscopic and microscopic observations with a digital loop were used to evaluate the detergent rate of the extract. The results of observations and calculations of color variations and acidity indicate the cleansing power of the hydro-alcoholic extract of Enzruth gum with an increase in its concentration with respect to the stain density. Thus, a more favorable and acceptable cleansing can be evaluated that by increasing the concentration up to 15 percent depending on the stain density, a better and more acceptable cleaning can be achieved. Evaluation of the performance of the extract on historical samples shows that it is a suitable extract for this work that can remove the thickest stains caused by hand contact in the historical papers without damage to the paper and the conservator.
