This research paper presents an applied study of reassembling inscribed stone pieces in the Grand Egyptian Museum. It covered one of the large archaeological limestone blocks divided into three parts. It was carried out in Saqqara excavations from the Kyiri Tomb, which dates back to the Eighteenth dynasty, numbered (1517GEM-CC) in the records of the Grand Egyptian Museum. The study was divided into two parts. First, inspection and analysis were carried out to identify the composition and components of blocks, damage, and previous restorations using ultraviolet microscopic imaging by a USB digital microscope, analysis by X-ray diffraction (XRD), and infrared spectroscopy (FTIR). Second, the engraved stone blocks were dismantled and reas-sembled using Araldite 1092 as an adhesive and Acryl 33 with stone powder as a binder after evaluating the use of Paraloid 72 immediately after revealing the defects of this previous assembly. The work stages included documentation using Auto CAD and the use of reflection transformation imaging (RTI).
