Pottery is one of the artistic-technical craft that has persisted for several millennia from prehistoric times to the present day. Such artifacts, particularly in Iran, exhibit high stylistic and technological diversity. In most archaeological excavations, consistently various types of these artifacts from different historical periods and styles have been discovered, whose technical study and form recovery can provide valuable information to researchers in various fields. Among these excavations is the Tappeh-Silveh in Piranshahr, where diverse pottery dating back to the Chalcolithic, Early Bronze Age, Iron Age, as well as remnants from the Parthian period and the subsequent Islamic period have been uncovered. The specimen studied in this article is a decorated orange pottery piece with black and red colors and geometric patterns, belonging to the Bronze Age from this site. This piece has sustained damages such as fractures, losses, and deposits, , which have been improperly repaired. It requires cleaning, reattachment, and reconstruction of the missing parts, while adhering to the theoretical principles of conservation. Accordingly, after necessary pathological and technical studies of the artifact using laboratory methods, an appropriate cleaning method was selected, and essential actions were taken towards its protection and restoration.
