Aqua Traiana is an ancient Roman aqueduct, built to supply water the city of Rome and still working nowadays. This work focused on characterization its mortars, in particular binders, identify reasons such a durable resistance. Samples collected inside aqueduct were analysed by Optical Microscopy (OM) thin sections, X-ray Powder Diffraction (XRPD), Scanning Electron with Energy-Dispersive Spectroscopy (SEM-EDS), High Resolution Field Emission (HR-FESEM-EDS), Microprobe (EMPA), Differential...
Currently, one of the most important challenges for conservation stone artworks is removal metal corrosion products on their surfaces. Traditional cleaning methods, which typically involve application aqueous solutions containing chelating agents capable complexing these ions, have shown some weaknesses. These weaknesses become apparent when such methods are applied to statues and other vertical surfaces or aiming limit process a specific area with controlled times. Furthermore, porosity...
Abstract A collection of ancient Roman orichalcum coins, i . e ., a copper-zinc alloy, minted under the reigns from Caesar to Domitianus, have been characterised using scanning electron microscopy (SEM-EDS) and microprobe analysis (EMPA). We studied, for first time, coins emitted by Romans after reforms Augustus (23 B.C.) Nero (63–64 A.D). These consisting asses , sestertii dupondii semisses were analysed non- invasive analyses, aiming explore microstructure, corrosive process acquire...
This work aimed to assess the potential efficacy of a novel polysaccharides-based extract as green consolidant for pictorial layer on marble substrates. Understanding its properties could lead determining whether it can ensure correct conservation and transmission cultural heritage. Four different types specimens were prepared with paint based malachite (egg, tempera grassa, rabbit glue, linseed oil binders). Colorimetric analyses, peeling tests, SEM-EDS, FTIR spectroscopy used test...
This study investigated the micro and nanoscale structure in Cu-Zn alloy, as well its corrosion patterns. To achieve this goal, a set of Roman orichalcum coins were analysed using Scanning Electron Microscopy (SEM-EDS), X-ray maps, high resolution field emission scanning electron microscopy (HR-FESEM-EDS) microprobe analyser (EMPA) techniques. The samples showed degree on their external surfaces, which evolved depth up to ~1 mm. Micro sub-micro imaging inner metal highlighted presence...
Orichalcum is a Cu-Zn based alloy known since the 1st millennium BC. The cementation was ancient technique used for its production. PhD project here presented aimed to characterise this and evaluate degradation: purpose, non-destructive, nano-invasive destructive techniques were on collection of coins issued from century BC end AD. In particular, multi-analytical approach used: investigate patinas their corrosive patterns, study microstructures degradation, describe dezincification process...
