Applications of Instrumental Analysis and Chemometry to Old Roman Mortars and Stuccos

Small quantities of roman mortars and stuccoes from the Theatre of Marcellus and Porticus of Octavia were subjected to different instrumental techniques, thermogravimetric analysis (TG, DTG), inductively coupled plasma emission spectroscopy (ICP), X ray diffraction (XRD). The instrumental characterisation and chemometry allowed to distinguish easily the stucco samples from the mortar samples.
