However, basalt is a very dense, compact and hard igneous stone; it is highly deterior-ated by physicochemical deterioration factors especially in the open air environments. Cracks are among the dangerous deterioration aspects in basaltic stones. They significantly contribute to accelerate their deterioration rates. Consequently, the cracks in basaltic stones have to be filled with a suitable mortar to stop their harmful impacts. In the present work, four types of organic binder based mortars were prepared and comparatively evaluated to select the best one for filling the cracks occurring in the studied archaeological basaltic stones at Abu Sir area. Examinations and analytical study were performed using transmission electron microscope, polarizing microscope, x-ray diffraction, colourimetric measurement, static water contact angle, compressive strength and scanning electron microscope attached with EDS. The results declared that the mortar named M4 (Acryclirsil + basaltic powder) is the most suitable composite for filling the cracks in the studied basalt.","PeriodicalId":41512,"journal":{"name":"Egyptian Journal of Archaeological and Restoration Studies","volume":" ","pages":""},"PeriodicalIF":0.2,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44439981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The acid breaks the Al-O bands and causes the cage to open permanently to allow access to the chromophore responsible for the color, released from the crystal structure and the loss of aluminum. Thus, a color change allows the release of the color-bearing radical anions. Thus, it is due to the natural ultramarine that has a stimulating effect on the dissolution of the binder (linseed oil), which leads to the appearance of a white dotted surface or heterogeneous white lines on the surface of the blue color or darkening dark gray more homogeneous. The study aims to study the mechanism of color change to grey whiteness in one of the oil paintings dating back to the late nineteenth century from the Gezira Museum in Cairo. It was carried out several examinations using stereo microscopy, polarized microscopy, spectroscopy photo by (VIS-UV-IR-IRFC), and analyses by color photometer, Raman and XRD methods, and related techniques (such as FTIR ART and SEM-EDX).","PeriodicalId":41512,"journal":{"name":"Egyptian Journal of Archaeological and Restoration Studies","volume":" ","pages":""},"PeriodicalIF":0.2,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47633471","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This mummy consists of five separated pieces (a mask, a pectoral, an apron, a stomach , and a foot) on canvas support topped by a ground layer decorated with green, yellow, red, black, and white colors and a gilded layer . All the pieces of the mummy cartonnage have damage in the form of separations, cracks, discoloration, tears, and brit tleness in the layers of the canvas support. The research paper presents the result of an examination and analytical study for the layers' structure of the mummy cartonnage. Therefore, the Optical Microscope (LOM), visible light, Scanning Electronic Microscope (SEM), EDX, Fourier Transform Infrared Spectroscopy (FTIR), X-Ray Diffraction (XRD), and XRF Spectroscopy were used. The results showed that canvas support made of linen in the form of four layers of thin fiber was used in the mask, stomach, and apron pieces . In contrast, one layer of thick fiber canvas was used in other pieces (mask, foot, and pectoral). The ground layer consisted of calcium carbonate, traces of gypsum, and quartz. The painted layer included Egyptian green, malachite , hematite, goethite, goethite with orpiment, graphite, and under layer of Egyptian blue below the green, red, and yellow pigments in a unique technique, especially in the pectoral and foot pieces. It was also noted that animal glue was used in all pigments and colors as a binding medium.","PeriodicalId":41512,"journal":{"name":"Egyptian Journal of Archaeological and Restoration Studies","volume":" ","pages":""},"PeriodicalIF":0.2,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49141334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present paper discusses the preparation of blue vitreous paint for nanoparticles Co 3 O 4 to improve its thermal and color properties. It compares the color prepared from the cobalt nano oxide Co 3 O 4 and cobalt oxide CoO mainly used to color the glass blue since the pharaonic periods. Examination and analysis methods , i.e., XRD, FTIR, SEM, EDX, and TEM, were used in characterizing the cobalt nano oxide. STEM, SEM, and stereo microscope were used to study the prepared color samples. Results showed that the particles size of the prepared Co 3 O 4 of 0.78 nm gave an excellent blue color when applied to the glass at a temperature of 620 °C compared to the color resulting from CoO, which was installed at a temperature of 700 °C according to mixing rates. That paved the way for reducing the proportion of the smelter in the color mixture to increase color resistance to weathering deterioration factors, especially moisture. of 620 °C; 80 °C lower than the color obtained from CoO , which allowed reducing the percentage of smelt in the color mixture. These properties help in facilitating the color completion of stained glass panels, which is an important problem facing the restorer during the restoration of archaeological glass panels. They also enhance the resistance of glass panels to weather deterioration factors, esp ecially humidity. Therefore, this study can con-tribute and pave the way in reserving stained glass panels considered a great part of the history of art.","PeriodicalId":41512,"journal":{"name":"Egyptian Journal of Archaeological and Restoration Studies","volume":" ","pages":""},"PeriodicalIF":0.2,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49175635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The hooked chin and facial details reveal a calm smile. On the outside, the statuette suffered from deterioration phenomena, for example different layers of soil mixed with sand and corrosion products on the statuette's surface. Bronze disease appears in separ ate areas of the statuette. Various examinations and analyses were performed on the samples that represent the places of damage on the statuette. The layers on the statuette surface were studied using stereo microscope examination, polarizing microscope and scanning electron microscope with energy dispersive X-ray analysis (SEM-EDX). Examinations show that the surface layers consist of clay minerals, sand and corrosion products in various colors. The mineral composition of the samples was determined by X-ray diffraction analysis. The analysis revealed the presence of cuprite, ata c-amite as Corrosion products, in addition to quartz. Calcifications have been removed using appropriate tools such brushes and blunt scalpels. Treatment processes of the bronze statuette include mechanical and chemical cleaning in addition to apply benzotriazole inhibitor by 3%. A protective layer of paraloid B 82 by 3% was applied.

An original sample was taken from the broken fractures of the sarcophagus and examined in terms of color, texture, and strength, then the same type of granite was brought from Aswan and crushed, then mixed with two types of Araldites, and white cement as binders. After evaluation of different mixtures, Araldite 1092 PY was chosen to be applied with coarse granite grains to be pre-casted and reinstalled.
