No full textThis paper presents the analytical data collected from the analyses of several cauldrons with crossattachments, perhaps better known under the German name Kreuzattaschenkessel. The analyses seem to confirm the hypothesis that these distinctive artifacts had been produced in two different periods and areas and show different characteristics. The chronology of the vessels is still not defined with certainty, but different shapes, different details, and different compositions seem to suggest that also in the later period there were two or more production sites. The implications of this fact and the related problems are discussed in this paper

No full textThis paper presents the latest data obtained from the analyses of fragments of Russian-Byzantine wall paintings recovered from the architectural excavations carried out in the church of St. George in the Yuriev Princely Monastery built in 1119 at Veliky Novgorod, one of the oldest cities in Russia and UNESCO World site. In the last 7 years the archaeologists of the Institute of Archaeology of the Russian Academy of Sciences in Moscow excavated the 12th century layers and extracted a large number of wall-paintings fragments, which are extremely important for the reconstruction of the history of Novgorod and for the study of Russian-Byzantine art in general. The pigments employed for the paintings and the painting techniques, together with color layers, substrates and mortars, have been studied and analyzed in the last two years in the Laboratory of the Architectural Archaeology and Multidisciplinary Methods for Architectural Research, Institute of Archaeology of the Russian Academy of Sciences. The employed analytical methods were optical microscopy (OM), X-ray Fluorescence Spectrometry (XRF) and Scanning Electron Microscope with Energy Dispersive Spectrometry (SEM-EDS). OM permits to distinguish the superficial painting method, the inclusions in the mortars, the intonaco and intonachino layers and the various substrates. XRF was applied for a first screening of the fragments and for the first pigment identification. The samples of painted mortar were then mounted in epoxy resin and polished for the analysis with SEM-EDS. The analytical data we possessed up to now indicate a very classical Byzantine technique with the use of expensive pigments such as lazurite and cinnabar, but also green earth, various types of ochres and mixtures of pigments. Special care was taken for the identification of the substrates
Surface characterisation techniques in the study and conservation of art and archaeological artefacts: a review
No full textKey issues related to surfaces and materials in the study and conservation of archaeological, artistic and historical objects are presented and illustrated with case studies. The materials cover a relatively broad chronological and compositional range. An important objective of the review is to inform the materials science and engineering community of the problems and needs of conservators, archaeologists, conservation specialists, art historians, archaeometrists and researchers in the field of ancient materials. In this way, improved technical information on methods designed to identify surface treatments and surface finishes, development of a common language among humanities and scientific researchers, and awareness of new applications appropriate in archaeometric studies can be promoted
LAZURITE AT NOVGOROD: TECHNIQUES, MIXTURES, PROVENANCE|LAZURIT NOVGORODBAN: TECHNIKÁK, KEVERÉKEK, SZÁRMAZÁS
No full textAn extensive collection of wall-painting fragments that in the 19th century was removed from the walls and buried under the floor of the Cathedral of St. George was collected during the 2013-2023 architectural and archaeological excavations on the area of the St. George’s Monastery at Veliky Novgorod (Russia), conducted by the Institute of Archaeology of the Russian Academy of Sciences. Among the pigments there were different kinds of blue, but the most common was rather pure lapis lazuli (lazurite), identified with XRF, SEM-EDS and XRD. Lazurite was the most valuable and expensive ancient pigment, as it was extracted and imported from few deposits, the most important of which was that of Sar-e-Sang in the Afghanistan region of Badakhshan
