Sažetak
Analysis of early-iron production remains by a combination of advanced instrumental methods is presented in this work. Samples were excavated in the Turopolje region, at the Okuje site, under the supervision of the Zagreb City Museum. The sample selection was guided mostly by their visual similarity. Different types of bloomery iron production debris were analyzed for an enlarged set of elements including major (Al, Ca, Fe, K, Mg, Mn, P, Si, Ti) to trace constituents (Cr, Cu, Mo, Ni, Pb, V, Zn, Zr, and REE’s), by use of a combination of plasma spectrometric methods with X-ray fluorescence (XRF) and scanning electron microscopy (SEM-EDS). The combination of morphological data obtained from SEM-EDS along with elemental signature and performed statistical treatment enables the identification of chemical characteristics of analysed archaeometallurgical remains. Using statistical analysis (PCA and HCA) on an enlarged set of measured data, the similar features of heterogeneous material become clearly discernible. Different types of slag, such as furnace slag, tap slag and ceramic-rich slag, were classified successfully according to their elemental fingerprint. The collected results might be of exceptional benefit for further studies of early- iron production in the Pannonian basin area.
