Decoding Ancient Flames: Chemical Fingerprinting and Innovative Cleaning of Archaeological Soot Deposits

Descripción del proyecto

Descifrar las huellas del fuego en la Antigüedad

Los depósitos de hollín antiguo en objetos arqueológicos se suelen tratar como residuos que deben eliminarse durante las intervenciones de conservación. Sin embargo, estos depósitos conservan información valiosa sobre las actividades humanas del pasado. En el proyecto Decode Ancient Flame, financiado por las acciones Marie Skłodowska-Curie, se creará la primera base de datos completa de huellas químicas de hollín antiguo a partir del análisis de muestras procedentes de más de veinte objetos egipcios mediante técnicas moleculares y espectroscópicas avanzadas. La comparación entre las firmas químicas del hollín con los datos arqueológicos permitirá reconstruir el uso de combustibles, las actividades domésticas y las prácticas culturales de la Antigüedad. La investigación también desarrollará y validará protocolos de limpieza sin contacto basados en tecnologías de plasma de oxígeno atómico y láser, integrados con sistemas de monitorización en tiempo real, para eliminar el hollín sin comprometer la integridad de materiales patrimoniales especialmente frágiles.

Objetivo

Ancient soot accumulation on cultural artifacts poses critical conservation challenges while offering unprecedented insights into historical human activities. This interdisciplinary project combines cutting-edge conservation technology with novel archaeometry analysis to revolutionize both artifact preservation and archaeological understanding.
We will develop a complementary non-contact cleaning technique integrating atomic oxygen plasma and laser cleaning to remove more than 90% of ancient soot while preserving artifact integrity. This green technology eliminates chemical solvents, addressing current limitations of traditional mechanical and wet cleaning methods that cause irreversible damage to sensitive ancient materials.
Analysis of more than 20 diverse cultural artifacts using advanced analytical and spectroscopic techniques (GC-MS, FT-IR) will create the first comprehensive database of ancient soot chemical signatures across geographical locations and historical periods in ancient Egypt.
Soot composition analysis will reconstruct daily life practices of ancient communities, including cooking methods, heating systems, fuel sources, and industrial activities. This novel approach bridges conservation science with historical research, generating new knowledge about technological advancement, diet, trade, and rituals of past societies.
Selected artifacts from Egyptian civilization will undergo systematic investigation using optical/electron microscopy, chemical analysis, and radiocarbon dating. Real-time integration of cleaning techniques with chemical analysis will increase efficiency by 50% compared to current separate processes.
The project will establish safety protocols exceeding current conservation standards. This proposal addresses urgent conservation needs while opening new frontiers in archaeometry, demonstrating how advanced analytical chemistry can unlock historical secrets preserved in ancient contamination layers.
