Overview

Experimental analysis of wood chemistry and radiocarbon dating reveals charcoal's history in ancient fires.

Key Points

  • This research aims to examine how wood chemistry and carbonization temperature influence charcoal's Raman spectra.
  • Quantified the effect of initial wood chemistry on Raman parameters using 41 wood species
  • Chemically characterized the species by FTIR and carbonized at 400, 600, and 800 °C
  • Analyzed archaeological charcoals from Matadi and Ndouni in Gabon for past uses.
  • Initial wood chemistry affects Raman parameters of charcoals, with varying sensitivity by carbonization temperature
  • Radiocarbon dating distinguished fire episodes at Matadi, revealing a higher fire intensity during the Early Iron Age
  • Charcoals from pottery showed stronger signals due to culinary use, compared to soil samples.
