New approach to the differentiation of marble samples using thermal analysis and chemometrics in order to identify provenance.

ABSTRACT:

Background

The possibility of applying a novel chemometric approach which could allow the differentiation of marble samples, all from different quarries located in the Mediterranean basin and frequently used in ancient times for artistic purposes, was investigated. By suggesting tentative or allowing to rule out unlikely attributions, this kind of differentiation could, indeed, be of valuable support to restorers and other professionals in the field of cultural heritage. EXPERIMENTAL DATA WERE OBTAINED ONLY USING THERMAL ANALYTICAL TECHNIQUES: Thermogravimetry (TG), Derivative Thermogravimetry (DTG) and Differential Thermal Analysis (DTA).

Results

The extraction of kinetic parameters from the curves obtained using these thermal analytical techniques allowed Activation Energy
