Evaluation of using Nanocomposite polymers in treatment of ancient Egyptian faience

Abstract

Ancient Egyptian faience is a significant object which hasenormous technical and historical information about Egyptian civilization. The recently discovered faience is exposed to many deterioration factors, which have a serious impact on its components and its physical and mechanical properties leading topoor structure, broken parts, and separated glazing layer.The current study aims to stop the continuous undesired effect of the deterioration factors and consolidate the recent discovered fiancé objects by using four different nanocomposite (Nanosilica SiO2 with Waker OH100 and TEOS as well as nano calcium hydroxide Ca(OH)2 ). The chosen consolidants (Polymernanomaterials) have been applied on simulated Egyptian blue faience object samples depending on an analytical study ofrecently discovered ancient faience objects at Tepla hill, Egyptusing XRD, and SEM_EDX.Porosity, water absorption, density, compressive strength, colorimetric measurements, water contact angle and Scanning electron microscope (SEM) were used to evaluate the efficiency of the selected consolidants, the result revealed that composite of nanosilica with Waker OH100 and TEOS were provide notable protection for the deteriorated faience.
