Abstract of the intervention:

 

The restoration was part of an ordinary teaching project on engravings from the Pogliaghi Fund, kept at the Ambrosiana Library, which involved students in the training course on library, archival, parchment and photographic materials (degree course in Conservation and Restoration of Cultural Heritage).

Restoration

The intervention on the incision of Valesio began with dry cleaning with a brush and scalpel to remove surface deposits, followed by the application of gel on the verso to eliminate the strip of paper. Subsequently, the folds were consolidated and the tears and gaps were compensated with Japanese paper and adhesive. The previous restorations have been removed and the chromatic integration with previously dyed paper has been carried out. Finally, a gradual washing and drying with absorbent paper, non-acid cartons and the aid of a weight were carried out.
