- Abstract:
- This paper reports the study and restoration of a 17th century wall painting attributed to the artist Lorenzo Berrettini and located in a chapel of Palazzo Orsini at Bomarzo, a little town close to Viterbo, in central Italy. The wall painting was recently restored as activity of a master thesis in conservation and restoration of cultural heritage and on that occasion the artwork was investigated to characterize the materials and techniques with the aim at choosing the best consolidation procedure and product. To reach this goal, multispectral imaging and X-ray fluorescence spectroscopy were applied on-site. After this non-invasive analysis, some laboratory investigation was performed by Fourier transform infrared spectroscopy. The results of the diagnostic campaign were used to plan the experimental tests for consolidation by diammonium phosphate dibasic (DAP) that is a relatively new product in the field of restoration of wall painting. The tests demonstrated the good performance of this consolidant product, in respect to traditional nano-lime formulate.
