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 Biasoli's engraving began with dry cleaning with a brush and microaspirator to remove surface deposits, followed by the contribution of moisture and the aid of the suction table to reduce dark coloring. Subsequently, the folds were consolidated and the tears and gaps were compensated with Japanese paper and adhesive and chromatic integration with previously dyed paper was performed. Finally, a gradual washing and drying with absorbent paper, non-acid cartons and the aid of a weight were carried out.
