Physics for Cultural Heritage

Head of Research
Giulia Festa
Overview

What is the recipe for preparations and medicines used in past times? How did ancient peoples forge metal? Is it possible to identify the author of a writing through the analysis of the ink used? These are just some of the questions that can be answered through interdisciplinary studies investigating the materials and artefacts of the past using tools and methods specific to scientific disciplines. Finds such as metals, ceramics, manuscripts, stone objects are analyzed using non-destructive and non-invasive chemical-physical techniques and the quantitative information obtained is fundamental for the definition of the attribution, the provenance of the materials, their dating, the state of conservation and the processing techniques.

Purpose and Goals

The “Physics for Cultural Heritage” research line is characterized by experimental analysis activities of materials of historical-artistic interest and by the use of innovative methods for data interpretation such as Machine Learning. Among the materials examined there are ceramics, metals, papers, fabrics, papyrus, inks, bones and organic finds. The aim of the research is archaeological-conservative issues that emerge from collaboration with archaeologists, conservators, chemists, museologists, anthropologists and archivists.

The experimental activities are carried out using the portable instrumentation available in the “Physics for Cultural Heritage” laboratory of the CREF, which can also be used in-situ at the Museums, possibly integrated by measurements at Large Scale Facilities through programs for access to advanced instrumentation neutrons and synchrotron radiation. The staff is also engaged in scientific dissemination activities relating to the line of research, in close connection with the museum and outreach activities of the organisation.

 

Contents and Methods

All studies are conducted using non-destructive and non-invasive techniques such as X-ray fluorescence (ED-XRF), Raman spectroscopy and Fourier transform infrared spectroscopy (FTIR) available in the CREF laboratory, and other techniques complements such as X-ray and neutron diffraction, gamma spectroscopy, X-ray and neutron imaging available through access to external research infrastructures.

The main research activities carried out or underway in the reference period are presented in detail below:

Pigments, binders and their interaction. The study involves experimental activities followed by multivariate statistics and Machine Learning for the analysis of paintings. Development of a new data analysis method for the characterization of paintings using spectroscopic techniques and Machine Learning. The study provides the basis for any analysis of paintings, with particular attention paid to the well-known painter Michelangelo Merisi, also known as Caravaggio.

In-situ neutron diffraction for the analysis of the crystalline structure of bones subjected to anaerobic combustion. The study allowed us to identify and quantify structural and crystallinity changes during heating under anaerobic conditions to identify temperature biomarkers. The work carried out, as well as in archaeology, can also impact forensic science, paving the way towards a new field of research.

Metallurgy in ancient Egypt. Study the processing techniques of metal vases from the Funerary Kit of Kha and Merit (Egyptian Museum of Turin) using X-ray diffraction and Machine Learning.

Mineral benchmarks in Sumerian ceramics. The study concerns the development of a new approach through FTIR spectroscopy and machine learning to identify primary and secondary phases and thermal alterations due to the cooking processes of raw materials. The procedure was applied to studying Sumerian ceramics from the archaeological site of Abu Tbeirah (4000-2000 BC) in Iraq.

Elemental and molecular benchmarks in EVOO. Development of an analytical procedure for quality monitoring, traceability and safety assessment in the food industry of Italian extra virgin olive oil (EVOO) using infrared spectroscopy, X-ray fluorescence and Machine Learning. In particular, it is possible to identify the geographical origin, the type of cultivar used, and any adulteration. The work has a significant impact on the field of Food Science.

Hydrogen Detection Limits and Instrument Sensitivity. Development of new methods for rigorously determining the instrumental sensitivity of inelastic neutron scattering (INS) spectrometers. The work provides a reference point against which to evaluate the performance of current and future tools.

Burial rites of Imperial Rome. The study concerns the analysis through vibrational spectroscopies of bone remains found in the Ghirlande Hypogeum, in Grottaferrata (Rome). The Ghirlande Hypogeum is an extraordinary Roman burial site dating back to the 1st-2nd century AD. and discovered in 2000. The results obtained provide significant elements for understanding the history of the site and the burial rites.

Preparations and medicines from the 17th and 18th centuries. Study in collaboration with the Medical Museum of Sapienza University of Rome, with the participation of Dr. Miriam Focaccia. The activities aim to understand pharmacology and pharmacopoeias as well as the formulations of ancient preparations and medicines. We adopted a multidisciplinary approach that combines chemical-physical characterization with historical-scientific information and cultural contextualization.

Manuscripts and book texts from the 17th and 18th centuries. Study in collaboration with the Pontifical Gregorian University of Rome regarding manuscripts such as the original copy of the magnum opus of the Jesuit Antonio Vieira (1608-1697 BC). The study involves the analysis of cutting-edge adhesives, inks, papers and restoration products to test their durability and effectiveness.

Study of the watermarks of the Corpus Chartarum Italicarum of the 16th century. Combined study of spectroscopic techniques such as all of Europe.

Numismatics. The study concerns the analysis of coins belonging to different collections of different historical periods and origins for the identification of specific benchmarks for attribution and authentication.

SiO2 nanoparticles. New conservation treatments of Pietraforte Arenaria tested on samples from Renaissance Palaces in Florence.

Neutron Imaging and machine learning techniques. Development of new imaging data analysis techniques for the optimization of new methodologies for the extraction of significant features.
