Abstract

Ovaj diplomski rad istražuje primjenu spektroskopskih metoda u karakterizaciji korozijskih produkata na 14 rimskih kovanica s dva različita nalazišta, s ciljem razvoja prijedloga optimalnih konzervatorsko-restauratorskih radova. Rad je podijeljen u tri glavna dijela. Prvi dio, Materijali i metode, pruža opsežnu teorijsku pozadinu potrebnu za potpuno razumijevanje problematike istraživanja. Obuhvaća povijesni kontekst rimskog novca kao artefakata te numizmatičku analizu kovanica koje su predmet istraživanja. Zatim se obrađuje važnost i princip funkcioniranja spektroskopskih analiza koje su korištene u ovom istraživanju. U posljednjem teorijskom bloku objašnjeni su korozijski procesi specifični za bronce od kojih su izrađene kovanice te su predstavljeni načini njihove kontrole u konzervatorsko-restauratorskoj struci. Drugi dio rada čine opsežna konzervatorsko-restauratorska i prirodoslovna istraživanja provedena na kovanicama, koja obuhvaćaju detaljnu dokumentaciju s izradom 3D modela kovanica, određivanje gustoće te FT-IR, XRD i XRF analiza izvedenih na odabranim kovanicama. Na temelju rezultata analiza identificirani su različiti korozijskih produkti, među kojima nisu pronađeni štetni kloridi. U trećem dijelu, na temelju rezultata prethodnih analiza, razvijen je prijedlog konzervatorsko-restauratorskih radova. U raspravi i zaključku istaknuti su najveće spoznaje, kao i nedostaci te su ponuđene preporuke za daljnja istraživanja i primjene u struci. Istraživanje naglašava važnost interdisciplinarnog pristupa koji s konzervacijom-restauracijom kombinira numizmatiku, arheologiju i prirodne znanosti kako bi se osiguralo optimalno očuvanje ovih povijesnih artefakata. Studija zaključuje da napredne spektroskopske tehnike mogu značajno doprinijeti boljem razumijevanju korozijskih procesa te razvoju učinkovitijih metoda za konzervaciju rimskih kovanica.

Abstract (english)

This master thesis investigates the application of spectroscopic methods in the characterization of corrosion products on 14 Roman coins from two different sites and, based on the findings, suggests optimal conservation and restoration treataments. The paper is divided into three main parts. The first part provides the extensive theoretical background necessary for a full understanding of the research issue. It includes the historical context of Roman coins as artifacts and the numismatic analysis of the coins that are the subject of research. Furthermore, the importance and principle of functioning of the spectroscopic analyzes used in this research are discussed. In the last theoretical block, the corrosion processes specific to the bronzes are explained so as the methods of their control in the conservation profession are presented. The second part of the thesis consists of extensive conservation-restoration research carried out on the coins, which includes detailed documentation with the creation of 3D models of all the 14 coins, density measurements and FT-IR, XRD and XRF analyzes performed on selected coins. Based on the results of the analysis, various corrosion products were identified, among which no harmful chlorides were found. In the third part, based on the results of previous analyses, a proposal for conservation-restoration treatments was developed. The research highlights the importance of an interdisciplinary approach combining numismatics, archaeology, natural sciences and conservation-restoration to ensure the optimal preservation of these historic artifacts. The study concludes that advanced spectroscopic techniques can significantly contribute to a better understanding of corrosion processes and the development of more effective methods for the conservation of Roman coins.
