Abstract: (1169 Views)
One of the most widely used terms in the conservation and restoration of cultural and historical artifacts, particularly in the field of ancient metal objects, is patina. Although, this term is also applied to other historical materials, such as paintings and stones, its frequent used in the context of ancient bronzes makes it essential to develop a clear and accurate understanding of its meaning and implications. From the perspective of the studying deterioration of the artifacts, patina-as corrosion products in bronze artifacts-can significantly impact both the tangible and intangible aspects of the objects. on the one hand, it contributes certain values, such as age and aesthetics. On the other hand, it serves as an important criterion in conservation and restoration practices. However, the lack of comprehensive and precise definition of this term leads to complexity in conservation decision-making. In this paper, based on a literature review, the differing and similarity viewpoints on patina have been investigated. Following this, the term is reviewed in relation to different corrosion morphologies, and issue related to its current definitions are discussed. The different values of the patina are debated, and its role in the principles of conservation is reevaluated. In this field, confusion arising from the application of the term patina in the conservation of archaeological bronzes have been highlighted. Finally, considering the unique properties of corrosion phenomena in archaeological bronzes, the concept of the “original surface” is discussed as an approach to addressing this issue.
