Volume 7, Issue 1 (6-2024)
Abstract
The measurement of the elemental composition of historical pottery is of particular importance. By examining the elemental composition of the body and glaze of historical pottery, one can obtain valuable information regarding the determination of raw materials and their diversity, as well as techniques employed in the manufacturing of these historical objects. In this research, 12 samples of the mina'i pottery from Alamut Castle, dating back to the 11th to 13th centuries AD, have been studied using ion beam analysis techniques. In this study, the elemental composition of the body, various pigments used in the paintings, and also the baseglaze have been measured using the micro-PIXE. Additionally, the thickness of the gold layer applied on the surfaces of some of these potteries has also been studied using the micro-RBS method. The purpose of conducting this research is to provide appropriate answers to the following questions: What raw materials have been used in the manufacturing of the body and glaze of these objects? What sources have supplied the raw materials used as fluxes? Also, what coloring agents and elements have been used to create different colors in the baseglaze and decorative paintings? Measuring the thickness of the gold layer used in these decorations is also one of the goals of this research work. Based on the results obtained from the elemental composition of the body and glaze of these potteries, it can be concluded that different sources of silica and fluxes have been used in the manufacturing of Alamut Castle mina'i potteries. Also, the coloring agents in producing red, white, blue, and turquoise pigments have been identified as Fe, Sn, Co and Cu elements, respectively. Moreover, the micro-RBS shows that the thickness of the gold layer used in decorations varies from 300 to 800 nanometers in the samples.

 
Research Paper Analysis of the Decuprification Process in the Corrosion Behavior of a Bronze Dagger
Fatemeh Alamirzaei, Parasto Naeimi Taraei,
Volume 7, Issue 3 (11-2024)
Abstract
The study of corrosion mechanisms in ancient bronze artifacts, particularly those from the salty and humid region of Hormuz, is crucial due to severe corrosion. This article examines a bronze dagger attributed to excavations in Hormuz to analyze its corrosion behavior influenced by the environment. Techniques such as X-ray imaging, stereomicroscopy, X-ray diffraction (XRD), polarized light microscopy (PLM), and scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDX) were employed. Results show that most of the dagger has transformed into corrosion products, including copper and tin oxides, as well as basic chloride compounds like atacamite and paratacamite, forming a three-layered corrosion structure. The corrosion mechanism involves selective dissolution of copper, its migration to outer layers, and the concentration of tin oxide compounds in the central regions, accompanied by chloride ion penetration. This process has preserved patterns of grain structure and thermal twinning in the inner oxide layers, with periodic deposition of copper and tin oxides indicating the formation of a colloidal solution of copper and tin salts beneath the soil (Scott, 2002; Robbiola et al., 1998).

Identification of pigments in wall paintings from the Zand era in the Karim Khani Castle of Shiraz

Volume 8, Issue 3 (11-2025)
Abstract
The Karim Khani Castle is a monument from the Zand era in Shiraz. In this building, a wall painting is one of the decorations, which unfortunately was hidden under a layer of plaster during the Qajar era, so many studies have not been conducted to identify pigments from the Zand era. The aim of the study is to understand the structure of pigments in the Zand period wall paintings in the Karim Khani Castle. The question raised is what kind of materials are included in the composition of these coloring materials. For investigation, FT-IR, SEM-EDS, and RAMAN instrumental methods were used. The findings indicate that the red pigment compositions included lead oxide (syringe) and possibly iron oxide (late), the blue pigment included ultramarine blue (lapis lazuli), and the green pigment included malachite (mountain green), which were applied on gypsum substrates and an oil-based compound was used as a binder. The pigments have a mineral structure and are durable, and despite the introduction of European oil paints in Iran, these color compounds have not been used in mural painting.

Reuse Adaptive an with Ilam in Castles Historical Five of Redesign Approach (3 Studio Design Architectural: Research Action)

Volume 8, Issue 4 (3-2026)
Abstract
The importance of the historical castles of Ilam province is above all because this region, as one of the government centers, was the site of the formation of prominent castles during the Sassanid period, which introduced the political and social structure of that era.  Over time, a number of these monuments have lost their original function and have become abandoned, making their preservation an inevitable necessity. Adaptive reuse through appropriate change of use is an effective solution for the restoration of these valuable buildings.  The main   question of the research is: "How can we help preserve and restore the historical castles of Ilam with an adaptive reuse (AR) approach?" The research method is mixed and data were collected and analyzed from documentary studies and field observations. The statistical population includes ten students of the sixth semester of the Bachelor of Architecture program at Jundi- Shapur University of Technology in Dezful, and the "Architectural Design 3" workshop was chosen as the research context. The results show that the focus of the designs was on creating new spaces and the strategy of annexation was used more than installation and intervention. Also, the annexations were mainly formed in the form of two groups of space and element and the most extensive changes were in the facade materials. The final result indicates that the adaptive reuse approach not only helps to preserve and restore the historical castles of Ilam, but also, in the form of educational projects, improves students' understanding of how to integrate contemporary design with the historical and physical values of heritage buildings.
