Abstract

The bowl under the research study is one of the artifacts damaged in the explosion of January 24, 2014 AD and dates back to the Mamluk era (Egypt or Syria) - (7th-8th century AH / 13-14th century AD) and bears record number (4306) and is smashed into many large and small fractions. The research dealt with a study Various manifestations of damage such as smashing or flaking, loss of some glaze, loss of cohesion of the previous assembly material from the glue, and fracture separation. An applied plan and scientific method for treatment and restoration began, so that scientific registration begins as the first stages of proper treatment, examination and analysis to determine the manifestations of damage by several methods such as: digital microscope, spectral analysis Infrared (FTIR), X-ray diffraction (XRD), Scanning Electron Microscopy equipped with an X-ray scattering unit (SEM-EDX) to analyze the components of the internal structure and the glaze layer, and the most important thing that the analyzes proved is that the internal structure of the bowl contains Silicon oxide Quartz low quartz and sand added 84.9%, and the research dealt with To the treatment, restoration and maintenance stages of mechanical and chemical cleaning and strengthening processes for the weak internal structure with Acrylic Silane, improved for its properties with fine nano-grains (1%) of nano-silica, which works to resist cracking by increasing its water- and moisture-repellent effectiveness, bonding of granules and resistance to disintegration, and nano-titanium (1%) ) Titanium dioxide (TiO2), which improves color with transparency and optical protection, what is known as the self-cleaning feature. Nano zinc (1%) Zinc Oxide ZnO also has high resistance to microbiological damage. Acrylic assembly materials such as Primal Ac33 or Paralloid B72 were applied, and the epoxy Araldite 1092 was used. In large parts that are not suitable with acrylic materials, and this was followed by completion processes that improved its properties by adding nanoparticles.
