The article presents an electron magnetic resonance study of metal paints in terms of identification and selection of appropriate pigment components based on the summation of spectral components. Research was carried out to assess the durability of paints on the basis of the detection of free radicals in individual components, the occurrence of which leads to paint degradation. Two types of acrylic resins, three types of organic pigments, and titanium white, hardener, and clearcoat were tested. The g-factor as well as all electron magnetic resonance line parameters were calculated. Electron magnetic resonance is found to be useful in the effort to eliminate a paint component that reduces color durability and to select components in terms of paint quality.
This article presents the results of archaeological and metallurgical research on two axes made of bronze, discovered in 2020 in two locations: Izdebki, Brzozów district and Gogołów, Strzyżów district. It was possible to determine the cultural context and chronological affiliation of the artefacts. The axe from Izdebki was classified as a type with elevated edges, dated to the BrB phase and associated with the Otomani-Füzesabony culture, whereas the item from Gogołów was classified as a socketed axe with ornamented sides, dated to the period corresponding to HaB1–HaB3. An analysis of the metallurgical composition of objects was carried out, examining the cores and their surfaces (corrosion layers). It was established that both axes represent so-called tin bronzes. The discovered artefacts should probably be considered loose finds.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
