Description
The surface was mechanically cleaned with scalpel under the microscope. Only the softer corrosion was removed. Thicker crystals of corrosion were left on the surface. The fragments were adhered together with HMG Paraloid B72 (methyl ethyl methacrlylate) applied with a cocktail stick. The excess of adhesive was removed with cotton swabs and acetone. A stitch of Nylon Gossamer was placed on the back to give further support to the join.
