ABSTRACT

The special session will focus on the analytical characterization of historical and archaeological materials derived from major forest by-products in Europe—Potash, pitch, Tar, Resin, and Charcoal (PoTaRCh). These materials represent a fundamental aspect of traditional forest exploitation and have played an integral role in various historical economies, crafts, and industries. Understanding their composition, transformation, and interactions with environmental factors is crucial for both heritage conservation and broader archaeological research.

TOPICS

The session will bring together researchers specializing in analytical and archaeological chemistry, material characterization, and conservation science to discuss the following key topics:

  • Exploring the origins and traditional technologies: Identification of historical production sites, raw material sources, and manufacturing techniques of PoTaRCh materials through compositional and isotopic analyses.
  • Chemical and analytical approaches: Utilizing modern analytical techniques, including spectroscopy, chromatography, and mass spectrometry, to determine chemical signatures, degradation processes, and environmental interactions of PoTaRCh materials.
  • Development of methodological frameworks: Establishing protocols for the identification of the biological origin of PoTaRCh materials, detecting technological and anthropogenic modifications, and defining new research directions in the field.
  • Interdisciplinary research perspectives: Bridging heritage science, environmental chemistry, and material analysis to enhance the understanding of PoTaRCh’s historical significance, economic impact, and conservation challenges.

This session invites contributions from researchers engaged in compositional analysis, methodological innovation, and case studies highlighting the application of analytical techniques to PoTaRCh-related materials. The session will foster discussions on best practices, challenges, and future directions in the analytical study of forest by-products within the framework of cultural heritage and archaeological sciences.

By integrating advanced analytical methods with historical and archaeological inquiry, this special session aims to provide a comprehensive perspective on the past of forest by-products and their role in shaping human history. This session is organized as part of COST Action CA22155 – EU-PoTaRCh (European Network on Potash, Tar, Resin, and Charcoal), specifically by Working Group 2 (WG2 – Analytical Characterization), which focuses on the compositional study and methodological approaches for the characterization of these materials.
