In this research, considering the necessity of conservation and restoration of wooden doors and their significance in Iranian architecture, as well as understanding the structure of historical wooden artifacts, necessary actions were taken to study, restore, and conserve a two-leaf wooden door belonging to the ivan of Sukiass house in Isfahan. Following preliminary damage assessment, various tests (including pH testing, colorimetry, equilibrium moisture content measurement, species identification, and Fourier-transform infrared spectroscopy) were conducted on the study sample. The results indicated the acidic nature of the structure of the sample under study, minimal color changes before and after the restoration process, standard equilibrium moisture content, the use of Oriental Plane tree wood (Platanus orientalis L) in the construction of the artifact, and the absence of significant structural damage on the sample surface. Historical wooden artifacts are typically classified into three main categories of physical, chemical, and biological damages. The study sample exhibited physical damages such as abrasion, cracking, and microcracks, environmental temperature effects resulting in color changes on the artifact,s surface, as well as the impacts of dust and debris. In the chemical damage category, tissue acidification in the artifact was observed, along with noticeable impacts of pollution. Biological damages caused by insect infestations, categorized under wood biological damages, were visible as multiple
boreholes on the artifact,s surface. Additionally, the presence of a burnt section at the lower part of one of the door leaves is another damage incurred by the study artifact. In line with conservation and aesthetic principles, necessary measures include cleaning the door and its frame, addressing deficiencies and cracks, protecting the artifact from pests, and applying polish and acid treatment.
