Retouching The retouching was aimed at regaining readability of shapes and the surface. The areas that had been reconstructed in the support and the ones that showed scratches and losses on the surface were retouched. In preparation, the filled areas were coated with a thick solution of ethyl cellulose ET200 (medical benzine and a small amount of toluene) to isolate the filling for subsequent retouching. Paraloid B72 and dry pigments were used as retouching agents, as was generally the case in this project. To distinguish the retouching as a restoration treatment, it was decided to use the Tratteggio technique. The Tratteggio lines were set in the direction of the original brush strokes.
