Stone consolidation is a crucial practice in the conservation of building and stone artifacts of Cultural Heritage. To prevent the irreversible loss of stone material, with significant cultural value, various consolidants have been studied over the last decades. However, the diverse properties of stone materials (limestone, biocalcarenite, and sandstone), the state of conservation of the...
This talk focuses on the urgent problems of synchrotron radiation damage to ancient paingtings. By the combined time resolved techniques of synchrotron radiation IR and ED-XAS in D-Line at SSRF, in situ radiation damage effect of paintings has been investigated. Results show that organic binders are easy to be damaged，especially when mixed with inorganic mineral pigments. And if the incident...
In this presentation I will highlight the non-destructive techniques offered by neutrons providing unique information about archaeological objects on selected examples. Neutron tomography is largely complementary to X-ray CT with remarkably high penetration of metals and excellent sensitivity for organic materials. It has e.g. been used to elucidate manufacturing techniques used to produce...
Advancing knowledge on the interactions occurring between conservation treatments and Cultural Heritage (CH) materials is a key point to plan effective conservation strategies. When dealing with inorganic-mineral products, the study of their diffusion within CH stone materials faces several analytical challenges, as non-destructive approaches, qualitative/quantitative phase analysis and high...
Museum objects with a painted metal structure are often found within industrial, scientific and technical collections. The conservation of these objects presents a challenge because of their composite nature. The interactions between the components of the system can lead to different alteration phenomena than what would be expected for the paint or metal alone, resulting in the need for...
X-ray beams produced by a synchrotron source have properties of high brilliance and spatial coherence that make them highly suitable for studying a range of ancient materials. For example, synchrotron X-ray methods have been used to study fossil teeth to determine the age at death of humans using X-ray micro-tomography [1] and to identify chemical elements as markers of provenance from...
