Aim of the present research is the characterization of the alteration patinas present on the surface of a marble Piety dating to Renaissance period and stored at the Castello Sforzesco of Milan. During the last century, a treatment was applied on the statue bringing to the formation of a dark patina which had to be removed. At this purpose a multianalytical approach, based on both portable noninvasive (XRF and colorimetric measurements) and micro-invasive techniques (FTIR/ATR and SEMEDS), has been applied in order to make available to restorers useful information that allow them to adopt a suitable procedure for the removal of the patina and to recover the statue original ppearance.

Abstract
Aim of the present research is the characterization of the alteration patinas present on the surface of a marble Piety dating to Renaissance period and stored at the Castello Sforzesco of Milan. During the last century, a treatment was applied on the statue bringing to the formation of a dark patina which had to be removed. At this purpose a multianalytical approach, based on both portable noninvasive (XRF and colorimetric measurements) and micro-invasive techniques (FTIR/ATR and SEMEDS), has been applied in order to make available to restorers useful information that allow them to adopt a suitable procedure for the removal of the patina and to recover the statue original ppearance.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
