- Conservation of archaeological copper alloy artifacts from Al Ain National Museum collection: the role of desalinationPublication . Lois, Diego; Vieira, Eduarda; Bosetto, EleonoraAl Ain National Museum is in the city of Al Ain, within the Emirate of Abu Dhabi, United Arab Emirates. This museum preserves an excellent collection of copper alloy archeological objects from different archeological sites around Al Ain all dated from the Neolithic era. We have observed a high concentration of chloride salts in most objects, which favors their corrosion. We conjecture that this may be the case for most sites located in arid zones near the coast. This paper aims to highlight the desalination treatments used during the conservation project of these artifacts. Desalination was the central treatment to achieve their stabilization and to promote their preservation for as long as possible. While the B70 desalination system has proven to be quite effective; salts still remain on the objects. Therefore, relative humidity and temperature monitoring are required to avoid variations that could reactivate sealed chlorides inside the objects.
- Intervention proposal for tram 177 Oporto’s (Portugal) tramway museum collection: Conservation as an alternative to restitution or reconstructionPublication . Lois, Diego; Vieira, Eduarda; Lorenzo, CarmenThis paper aims to discuss the intervention proposal for the conservation of the Tram 177 from Oporto´s Tramway Museum Collection. We want to highlight a new approach that permits a different result from the one usually obtained in the Museum´s practice, where reconstruction and restitution became more important than conservation. Framed within minimal intervention guidelines, our proposal has as goals both the preservation of the vehicle original layout as well as its technical and historical values.
