Unfortunately, these heritage elements have experienced considerable deterioration. This paper presents the results of a project whose main goal was the scientific investigation of the Imperial Gates belonging to the wooden church in Sălișca, Cluj County, Romania. To digitally preserve and document the Imperial Gates, a scientific investigation into the wooden support and the painting materials (ground, pigments) were performed using Fourier transform infrared (FTIR) and x-ray fluorescence (XRF) spectroscopy. FTIR spectroscopy provided information about the wooden support, whereas XRF and FTIR methods were used to structurally characterize the painting materials.
