Abstract
The following article aims to conserve and restore a part of the rock door and stone tower of the Pasargad World Heritage Site. The rock piece belongs to the right wing of the stone tower and is decorated with six lotus flowers. This object had much damage that caused the preservation and protection of the work to problems such as fracture and lack of integrity. Therefore, the restoration practice started on the stone piece. The best intervention method is selected after the historical, physical, and chemical knowledge of the effect. In this regard, studies have been conducted in the field of knowing and investigating the political history, architecture, nature, and use of the rock tower, and instrumental analyses such as petrography, X-ray diffraction (XRD), X-ray fluorescence (XRF) have been performed to identify the physical and chemical dimension of the object. The results show that the work belonged to the stone tower and was probably built during the reign of Darius. The rock used to build the artefact is dolomitic limestone. Finally, with the help of the mentioned analyses and according to the restoration principles of restoration, practical procedure, and preventive conservation were carried out on the stone piece. Finally, the work was placed inside a frame made of Teflon sheet for display so that the work has both visual integrity and can be reversed for future restorations.
Pottery is one of the most important man-made artifacts, and with time, its manufacturing and application technology has also changed. Therefore, in most archaeological excavations, pottery artifacts occupy a major part of the discoveries, and most of these artifacts have special damages. Some of these damages are common, such as fractures and cracks, and some are special due to the burial conditions and low quality in the construction technique; Such as body layering damage that requires special protection and restoration studies. In this study, a sample of terracotta cauldron hanging on the Segzabad hill of Qazvin Plain belonging to the Iron Age period was studied. This study aimed to understand the construction technique, investigate the damages on the pottery body and the cause of these damages. To answer these questions, instrumental tests, such as XRF, and comparative historical studies have been used. All these studies will ultimately help in the way of conservation and restoration that should be done. After all the protective steps to prevent secondary damage that may occur after its restoration, a box is designed to store the pottery and, in some cases, even display it. The result obtained from all the steps was the recognition of the construction technique and the documentation of the damage in the body, which ultimately led to the protection and restoration of this historical and cultural work.
