During this year we did not perform any in situ expedition to Pompeii. The previous year, the members of EPUH project finished their excavation works in the Insula IX from the archaeological site of Pompeii and concretely in the House of Marcus Lucretius. For that reason, the Soprintendenza of Pompeii decided to open this house to the visitors.

Nevertheless, considering that we produce lot of data during our previous in situ campaigns and laboratory analyses, we dedicated this year to perform data treatment and additional laboratory analyses. Concretely during this year we performed additional analyses of the plasters and wall painting fragments collected in our previous expeditions in the House of Marcus Lucretius and we also performed additional analyses of volcanic material (ashes and pumice) collected previously and small samples of pigments collected from the pigment collection of Pompeii (original pigment bowls collected from the burial in the first excavations) preserved in the Naples National Archaeological Museum.

In this year we also presented on oral contribution in the “ 7th International Congress on the Application of Raman Spectroscopy in Art and Archaeology” celebrated from the 2nd-6th September 2013 in Ljubljana. In this contribution we present the usefulness of our non-invasive  portable methodology to characterize the nature and distribution of salts crystallized on the surface (efflorescences) of wall and wall paintings from the House of Marcus Lucretius and Obonius.

This year also Héctor Morillas presented an oral contribution in the conference “6th International Congress Science and Technology for the de Safeguard of Cultural Heritage in the Mediterranean Basin” which allowed to establish a collaboration with researchers of the University of Valencia in order to continue applying our non-invasive methodology in an additional and well-known house of Pompeii, the House of Ariadne.
