Abstract:
This paper reports the results of the diagnostic investigation conducted on the "boiserie" of the Rococo Hall at Palazzo Fizzarotti (1850-1908) in Bari. The boiserie is an artifact made of faux marble with included seminato elements and characterized by the presence of assembly plastering.
The study aimed to identify its constituent materials, reconstruct the production technique, and understand its conservation state to carry out a critical restoration work which respected the boiserie from a material, historical and aesthetic point of view.
Non-invasive analysis took place in situ (colorimetry, pXRF, UVF) and in laboratory (OM, SEM-EDS, µRaman, XRPD).
The results revealed the use of Sorel cement for the surface mortar layer in the faux marble elements (including the assemblage plastering) and the use of Portland cement in the "seminato" elements and the plastering depth layer, other than the technological aspects and the forms of the degradation.
