Context: Presented at the International Istanbul Historical Peninsula Symposium / Experimental Research Workshop (2013).
Collaboration: A joint study by the Directorate of Istanbul Central Laboratory of Restoration and Conservation and the Turkish Atomic Energy Authority (TAEK).
This research focuses on the strategic role of Radiography as an essential Non-Destructive Testing (NDT) method for the investigation of archaeological and historical artifacts. Beyond simple imaging, this study aims to introduce the vast potential of radiographic data to conservators and archaeologists, fostering a discussion on its role in authentic restoration and technical documentation.
Revealing Hidden Structures: Radiography allows for a “transparent” view of artifacts, uncovering internal structural details, manufacturing methods, and hidden signs or forgeries without any physical intervention.
Deciphering Production Methods: Using X-ray and Gamma-ray techniques, the study presents findings on iconic artifacts including the Golden Horn Chains, Byzantine Anchors, and the Serpent Column (Yılanlı Sütun) from Sultanahmet Square. For instance, radiographic evidence on the Golden Horn chains identified sub-surface air gaps and forging overlaps, revealing a complex transition from liquid casting to hammer forging.
Forensic Investigation of Encrusted Objects: The research highlights the “Forensic Conservation” approach by using Flat Panel Digital Radiography to see through thick corrosion layers. This was crucial for the Yenikapı shipwrecks, where it allowed for the identification of original iron cores beneath marine concretions, guiding precise cleaning and reconstruction.
Replica Support: Radiographic images were used as primary blueprints for creating high-fidelity replicas, ensuring that the internal structural logic of the original artifacts was preserved in the modern reproductions.
By documenting these advanced imaging protocols, the study establishes radiography as a standard diagnostic tool in Turkish museology. It demonstrates that the conservator’s role is not just to “repair,” but to “decode” the physical history of an object, providing a permanent visual archive for artifacts prone to inevitable decay.
