Report on Conservation and Restoration of Chehrabad Salt Mine Pottery Collection

Due to the instability and sometimes sensitivity of archaeological objects, conservation and restoration of them usually require a complex procedure along with basic studies and pathology in the restoration process. Since pottery objects are more stable than other objects, they can be restored after preliminary investigation regarding the level of strength and hardness of surface sediments, if there is no special problem. In this report, we introduce and describe the conservation and restoration process of a number of Zanjan salt men collection pottery, transferred from the Zulfiqari Museum of Zanjan to the pottery department of the Research Center for Conservation of Cultural Relics for conservation and restoration operations. These objects, which were sometimes cleaned and temporarily patched at the excavation site, were thoroughly checked and all connections were opened. The parts were cleaned separately using various mechanical and chemical methods and after finding the correct parts, the connection was made again. Finally, the parts that needed to be reconstructed were reconstructed with plaster following the pattern designed for this collection and considering the basics of restoration.
