Abstract of the intervention:

 

The restoration was part of an ordinary teaching project on some engravings of 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 Bulzoni's engraving began with the cleaning of the recto with microaspiration and of the verso with brushes and rubbers. In addition, the letter "C" has been removed from the verse for conservation reasons, the inventory number has been transposed and the ink inscription has been consolidated with fluorine. Two hot water baths were followed for the removal of adhesive tapes. Subsequently, the tears and gaps were compensated with Japanese paper and adhesive and the previous restoration works were removed. The chromatic integrations were carried out with previously dyed paper and the rebondings with resin. Finally, a nebulization wash and drying with absorbent paper, non-acid cartons and the aid of a weight were carried out.
