آليات تأثير الحبر العفصي الحديدي على المخطوطات و طرق المعالجة

Abstract EN

This article is about the iron-gallic ink which is considered as the main intrinsic factor that causes the degradation of ancient manuscripts texts, especially those copied on paper support.

This degradation is most often the result of the oxidation and hydrolysis processes of the cellulose that the manuscripts encountered in inadequate storage conditions.

Judging from the recipes and ingredients of this ink presented in ancient texts, chemical studies demonstrated how the mechanisms interactions of ink with weathering factors lead to chemical alterations could affect the cellulose.

As well as, lab researches have experimented curative treatments in order to cure the ink effects on paper, also, they settled old recipes into practice and techniques for reviving faded ink, and fixing it before any aqua treatments of the paper, and thus, saving the texts and stop any eventual degradation in the future.

These have fortunately witnessed a good response to these objectives, which have resulted in improving the conditions of preservation of this cultural heritage.
