Abstract

Treatment and conservation operations are considered the most important processes for preserving cultural heritage collections, in particular archaeological textiles. This research outlines the methods used for treating and preserving an ancient piece of linen textile recovered from the Qusayr excavations in the Red Sea. The piece was cleaned using the traditional detergent “Orvus WA Paste surfactant”, and then, it was consolidated to prevent damage and  combat the  microbiological attack using silver nanoparticles loaded on hydroxypropyl cellulose polymer (AgNPs/Klucel G). Various methods were employed to diagnose the decay of the artifact. Scanning electron microscope coupled with an energy-dispersive X-ray unit (SEM-EDX) was used to scrutinize the surface morphology and determine the elemental composition of the archaeological piece. X-ray diffraction (XRD) was employed to ascertain the rate of cellulose crystallization of the piece. According to the results; it was deduced that, the artifact was found in an area near the sea, which was confirmed by the presence of sodium chloride salt residues on its surface. The microbiological study demonstrated that AgNPs/Klucel G was effective in inhibiting fungal strains that were isolated from the artifact.

Highlights

  • Documenting and diagnosing the degradation aspects of the artifact using various examination and analysis methods.
  • Evaluating the effectiveness of the surfactant and nanocomposites in the treatment and conservation of the archaeological piece.
  • Clarifying the condition of the archaeological linen piece before and after the treatment process.
