STUDY VISITS – ANALYSIS OF FINDS IN MUSEUMS

18–20 December 2025

During the study visit to the Archaeological Museum in Osijek, documentation and material related to iron metallurgy from the rescue archaeological excavations at the Osijek – Barracks–University/Student Pavilion site were examined. These excavations were conducted between September 2012 and May 2013. Following macroscopic analysis of slag and furnace wall fragments, samples were selected for further mineralogical and chemical analyses (Tena Karavidović, Slavica Filipović, Tajana Sekelj Ivančan).

During the visit to the Faculty of Metallurgy in Sisak, selected semi-products/ingots from Hrvatska Dubica (13), discovered in 1880, and one iron semi-product found during dredging of the Kupa River near Sisak were sampled for the purpose of conducting further analyses (Tena Karavidović, Ivan Jandrlić, Tajana Sekelj Ivančan).

 

19 November 2025

During the study visit to the Sisak City Museum, semi-products/ingots from Sisak (6) were examined. Following macroscopic morphological analysis, samples (4) were selected for planned further analyses:

  1. metallographic analysis – optical microscopy, hardness testing, SEM-EDS – characteristics of the semi-products;
  2. chemical analysis – ICP-MS (AES) of slag inclusions within the semi-products – provenance studies;
  3. radiocarbon (¹⁴C) dating of carbon in the metal – absolute dating of artefacts without a clear archaeological chronological context

12–14 November 2025

During the study visit to the Archaeological Museum in Zagreb, semi-products/ingots from Hrvatska Dubica (27), discovered in 1880, and one iron semi-product found during dredging of the Kupa River near Sisak were examined. Following macroscopic morphological analysis and surface chemical analysis of the artefacts (pXRF), samples (13+1) were selected for planned further analyses:

  1. metallographic analysis – optical microscopy, hardness testing, SEM-EDS – characteristics of the semi-products;
  2. chemical analysis – ICP-MS (AES) of slag inclusions within the semi-products – provenance studies;
  3. radiocarbon (¹⁴C) dating of carbon in the metal – absolute dating of artefacts without a clear archaeological chronological context

November 20-26, 2024

During the study stay at the Archaeological Museum in Osijek, documentation and materials related to iron metallurgy from the research of the location Osijek - Vojarna - Faculty of Agriculture, which were carried out in 2003-2005, were reviewed. After the macroscopic analysis of the slag and furnace walls, samples were selected for further metallographic, mineralogical and chemical analysis (Slavica Filipović, Tena Karavidović, Tajana Sekelj Ivančan)
