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 the incision of Biasoli began with dry cleaning with a brush and scalpel to remove surface deposits, followed by the contribution of moisture to reduce the dark coloration caused by gores. Subsequently, the tears and gaps were compensated with Japanese paper and adhesive and the previous restoration works were removed. The chromatic additions were made with previously dyed paper. Finally, a washing and drying with absorbent paper, non-acid cartons and the aid of a weight were carried out.
