Conservative restoration of the Augustus Arch of Fano: cleaning methodology as derived from preparatory analyses and sampling.
The original appearance of Augustus Arch of Fano was compromised by a diffuse distribution of black scales and other deposits. In order to preserve the stone surface the restoration intervention operated with different cleaning techniques so that it was possible to use every method with a properly and not dangerous intensity. In particular it showed the possibility to use laser cleaning to destroy the external hard part of black scales, and complete the intervention with light chemical cleaning. In the case of Augustus Arch this way resulted useful for preserve signs on surface and cleaning every kind of deposits at the same time. Every intervention on such an important monument need to obtain at the same time the best result for materials conservation and the aim of image restore.
