... Therefore, the study of unearthed cultural relics is no longer limited to the morphological observations or compositional analysis of the golden surface (Ingo et al. 2007). Instead, it goes deep into the interior of the cultural relics to study the compositional distribution and structural characteristics of the cross-section and the interface between the gold layer and the substrate (Ottenwelter et al. 2020), revealing the forming mechanism of the gold layer during the gilding process . It is worth mentioning that the heating causes phase change of Au-Hg amalgam during the gilding process, thereby forming a gold layer (Jin et al. 2017). ...

... The study focuses on central European gilded copper jewellery, for which fire gilding was largely applied (Ottenwelter, in press). It concerns the fire gilding layers of specific archaeological artefacts found in Bohemia (Lumbe Garden cemetery at Prague Castle): gombiky (spherical hollow pendants) and medallions, characteristic pieces of the elite jewellery from the 9th and 10th centuries AD, detailed in previous studies (Ottenwelter et al., 2014;Ottenwelter et al., 2017;Ottenwelter et al., 2020;Ottenwelter, in press). The use of FIB FEG-SEM allows crosssections to be made and observations performed in situ within the SEM (Johnson et al., 2012;Chiavari et al., 2015;Masi et al., 2016, Masi et al., 2017. ...
