More information

The laboratory of the National Archaeological Museum has as its main area of action the conservation and the restoration of metal objects, ceramics, stone and organic objects coming from archaeological contexts, from the museum collections and, in some cases, objects belonging to other museums and institutions. Another field of action and inseparable from all the other areas is preventive conservation, essential to ensure the preservation of the collections.

The philosophy of the laboratory is based on the respect for the perennial quality and for the integrity of the object and is ruled by the deontological principles of conservation and restoration.
To perform well the objectives we propose, we consider that the course, which takes the archaeological objects from discovery to exhibition is long, and that in between lie numerous actions of conservation and restoration, which can allow a better knowledge of materials and making processes. No intervention of conservation and restoration can be seen as a trivial episode in the life of a cultural good, but it should rather obey the following sequence of requisites:
preliminary diagnosis of the state of the object and of its cultural meaning; systematic register of every action performed; minimal intervention, keeping the original integrity of the object and always justifying the need to add new materials; preventive conservation, trying to anticipate future situations susceptible of causing damaging effects; visibility of the interventions, in such a way as to make any reconstitution easy to identify, although without affecting the interpretation of the object; reversibility of the interventions, ensuring the possibility to annul actions and remove the materials added, without damaging the original integrity of the object; compatibility of the materials used with the physic-chemical and even the visual nature of the object.

The best way to limit the risks inherent to any intervention of conservation and restoration is the interdisciplinary dialogue between all the specialists involved, especially between the conservator-restorer, the museum curator and the archaeologist.
