Piazza Ferrari a Rimini: il mosaico del triclinio nella "Domus del Chirurgo". Un intervento tra restauro e manutenzione

On the occasion of the opening to the public of the Roman "Domus del Chirurgo" in the centre of Rimini a new conservation intervention was carried out on the floor mosaic of the Triclinium room, previously subjected to different and often bad restoration interventions. The conservation works were supported by the characterization, by means different analytical techniques, both of the original mosaic materials (tesserae and mortars) and of the restoration products used in the past. The deterioration processes of these ancient and modern materials were also identified. In the new restoration intervention the unfit and not compatible mortars used in the past were removed and restoration mortars with a composition similar to the original ones were prepared and applied. Finally a long and careful microclimatic study was also performed and a programme of maintenance was planned
