Preserving textile objects in Romanian wooden churches. Case study of the heritage wooden church form Oradea, Romania

Abstract

It is important to investigate the indoor air quality, the microbial concentration of indoor air and surfaces for preserving the cultural heritage. In what regards the microclimate inside the historic monument, the wooden church, the temperature and relative humidity were monitored using the thermo-hygrometer with data function logger “Klimalogg Pro” (eight sensors), October-December 2018, the thermos-camera “Thermal Imaging Camera FLIR I7” and “Digi-Sense Data Logging Luxmeter”. Image analysis were also performed using digital image processing techniques (ARCGIS), mapping the areas damaged by temperature, humidity and also by rainwater infiltrated on canvas paintings, biodegradation, anthropically degraded areas etc. Isolation of microorganisms from the two canvas paintings and indoor air were taken though specific method, analyses showing the presence of microorganisms on the paintings, possible human pathogens especially for people with low immunity. A high fidelity database with the state of patrimony objects preserved in the Romanian wooden church and perspectives for their proper conservation could be created at a certain moment.
