Key research themes
1. How can multi-method archaeometric analysis improve provenance identification of colored marbles in ancient artifacts?
This research theme addresses the challenge of definitively identifying the geological origin of colored marbles used in ancient artifacts and architecture. Accurate provenance determination is crucial for understanding ancient trade networks, quarrying practices, and cultural interactions. Due to similar petrographic and geochemical characteristics among marbles from different regions, multi-analytical approaches combining mineralogical, isotopic, elemental, and topographical data have been developed to increase reliability and discrimination power in marble sourcing.
2. What are the causes and mechanisms underlying chromatic alteration and discoloration in colored marble artworks and how can non-invasive analytical techniques guide cleaning treatments?
This theme investigates the chemical and physical processes responsible for color changes and discoloration in colored marble sculptures and architectural elements, which can compromise both aesthetic and material integrity. Identifying the nature of discoloration—whether due to environmental deposits, alteration of protective coatings, or biological colonization—is essential for the development of suitable and minimally invasive restoration and cleaning strategies. The use of spectrocolorimetry, reflectance spectroscopy, multispectral imaging, and other non-invasive analytical methods enables detailed characterization without damaging valuable artworks.
3. How do historical and contemporary techniques reproduce or manipulate the color and appearance of marble in art and architecture?
This theme covers the exploration of both ancient and modern artistic methods for producing color variation and visual effects in marble, including imitation via painting and glazing, as well as composite use of differently colored marble types in sculpture and architecture. Understanding these techniques informs the interpretation, authentication, and conservation of polychromatic marble surfaces and monuments by distinguishing genuine natural coloration from artistic or technological interventions.
