Microchemical surface analysis of historic copper-based coins by the combined use of FIB-FESEM-EDX, OM, FTIR spectroscopy and solid-state electrochem…

[EN] A multi-technique strategy, including microscopy, spectroscopic and electrochemical techniques, is proposed to study thin corrosion layers that form on the surface of historic copper-based coins. An accurate characterisation of this external corrosion layer is important for selecting a suitable conservation and/or restoration treatment. For this purpose, a series of copper-based coins from different historical periods and provenances, which mainly exhibited atmospheric corrosion, was analysed. The morphology of the corrosion layer and the upper core of coins was studied in trenches done on coin surfaces with a focused ion beam gun, coupled to a field emission scanning electron microsco…
Salt extraction from lime-based mortars: An experimental study using different poultice formulations
2020
Abstract The extractive capability of soluble salts in poultices treatments currently used in mortar conservation (ArbocelTM plus sepiolite; ArbocelTM, sepiolite and sand; Westox-Cocoon®) were tested to evaluate their efficiency and compatibility with specific mortar substrate. The pore size distribution of the experimental mortar substrate and of the blank dried poultices were preliminarily accomplished by mercury intrusion porosimetry (MIP). Desalination tests were carried out on specifically-formulated mortars after capillary absorption of Na2SO4 0.3 M solution. The efficiency of salt extraction was measured by means of electrical conductivity meter and ion chromatography. Among the test…
Semantic Wiki for the Protection, Emergency Management and Knowledge of Cultural Heritage
2012
Nowadays, the trend for cultural heritage data management is the generation of numerical corpus that can be viewed and distributed online. To make information available on the web and to provide easy access a web platform application is needed it will be important to make use of a web platform that allows easy creation and editing of web pages as well as a management of their links. Wiki semantico per la tutela, la conoscenza e la gestione dell’emergenza Fornire un accesso alle informazioni relative al patrimonio culturale al di là del supporto che possono fornite i testi, è importante. Per far fronte a specifi che esigenze è richiesto un supporto semantico avanzato. Per gli specialisti (co…
Open-air Conservation of Ruins and the Concept of “Non-Dislocation”
2012
Most of the on-going debate is about “how” to protect archaeological ruins, whilst at the same time allowing the general public to enjoy them. Today it is clear how important it is, from the actual planning stages of excavations, to interact with experts from other disciplines, who are working on their own findings and offering them up for collective enjoyment. Whatever might be feasible for an indoor museum is not always feasible with an architectonic ruin, as regards both presenting objects with explicative apparatus that determines their significance, and exploring them in a new way when interpretations change or new ideologies are introduced. First of all, conserving excavations is the …
