Abstract
Purpose
The purpose of this study is to detect the effect of some natural cellulosic polymers in their nano forms with the addition of zinc oxide nanoparticles on restoring the lost mechanical strength of degraded papyrus without any harmful effects on the inks.
Design/methodology/approach
In the current study, the USB digital microscopy, scanning electron microscope, measurement of mechanical properties (tensile and elongation), pH measurement, color change and infrared spectroscopy were undertaken for the samples before and after treatment and aging.
Findings
In the current study, the USB digital microscopy, scanning electron microscope, measurement of mechanical properties (tensile and elongation), pH measurement, color change and infrared spectroscopy were undertaken for the samples before and after treatment and aging.
Originality/value
The effect of strengthening materials was studied on cellulose and carbon ink, which makes this study closer to reality as the manuscript is the consistent structure of cellulose and inks, whereas most of the literature stated the impact of consolidation materials on the strengthening the cellulosic supports without attention to their impact on inks.

Abstract
Purpose
The purpose of this study is to determine the nature of archaeological papyrus damage and monitoring the mechanics of damage caused by black inks to the chemical properties of ancient papyrus.
Design/methodology/approach
This study the papyrus surface with a digital microscopy “USB,” examination and analyzing by “Scanning Electron Microscope,” characterization of black ink used in writing the ancient papyrus using “Scanning Electron Microscopy” with (EDX). Detection of changes in the chemical bonds of ancient papyrus samples by “Fourier transform infrared” FTIR.
Findings
The result confirmed that SEM examination showed the organization of the parenchyma cells that make up papyrus tissue. Characteristic waveform appears, it indicates the ancient Egyptian manufacturer’s use of the (Strips Method) in the process of manufacturing the archaeological papyrus. Also, the appearance of (Over Lapping) stacking of papyrus slides. EDX analysis showed that the black ink used to write the papyrus was (Carbon Ink). High oxygen content in the papyrus sample analysis indicates deterioration of the cellulose fibers. FTIR spectrum showed that Arabic gum is the bonding material for carbon ink particles, it also showed that archaeological papyrus suffers from hydrolysis due to exposure of papyrus fibers to high moisture content or direct water, resulting in smudge, bleeding and fading of carbon ink on the archaeological papyrus support.
Originality/value
The study is archaeological papyrus with black ink scripts from the excavation of the Qasr I brim.
