- Abstract:
- The aim of the research presented in this paper is to monitor the stability of three protective products applied on samples of Peperino stone, a volcanic tuff widely used for the historic buildings and architectural elements in Viterbo (Italy), using portable devices. More in detail, two different monitoring techniques were applied: VIS-NIR point spectroscopy (400-1000 nm), and colorimetry. In order to characterize the compositional variability and homogeneity of the samples, X-ray micro-fluorescence (micro-XRF) was preliminary used. Data were acquired before and after the application of the different products in order to monitor and detect the efficiency of the considered low-impact products. Peperino samples were also aged in a Solar Box chamber for 1000 h to simulate a solar irradiation and measurements were repeated at the end of the ageing period to evaluate the stability of the protective products.
