Title: Protocol for Investigating Ancient Colours: A Multi-Analytical, Non-Destructive Approach to the Study of Roman Painted Plasters
Description:
This proposal aims to present an integrated and replicable protocol for the characterisation of ancient pigments using non-destructive techniques, based on several case studies from Roman north-central Etruria. The study outlines a multi-analytical methodology, both macroscopic and microscopic, which combines portable, non-invasive, and micro-invasive techniques such as XRF, Raman, ATR-FTIR, FORS, and HSI.
The integration of these tools makes it possible to obtain a comprehensive screening of painted surfaces, useful for distinguishing compositions, production processes, and application methods. The work discusses the potential and limitations of each technique, highlighting the advantages of using portable instruments that do not require sampling or specimen preparation.
In conclusion, the research demonstrates that a multi-proxy approach significantly improves our understanding of Roman pictorial materials and their production technologies, offering an operational model for future diagnostic and archaeometric investigations..
