BEFORE TREATMENT

The engraving exhibited an overall discoloration with additional light brown water staining within the margins. The paper support was moderately distorted.

BEFORE TREATMENT

The chine-colle was adhered overall between a poor quality window mat and backboard. Brown mold staining was scattered throughout.

AFTER TREATMENT

The print was surface cleaned to reduce particulate grime. It was bathed to reduce discoloration and degradation products. Finally, the print was humidified and pressed to return to plane.

AFTER TREATMENT

The poor quality window mat and backboard were removed mechanically. Residual paper and adhesive was reduced using moisture. The chine-colle was humidified and bathed to reduce discoloration and degradation products. Mold stains were lightened with a dilute oxidizing agent. It was humidified and pressed flat.

BEFORE TREATMENT

The parchment document was tightly and stiffly rolled with water-damage along the right edge, causing further stiffness and shrinkage of the skin. 

AFTER TREATMENT

The parchment document was surface cleaned to reduce grime on areas that could be reached. It was humidified in succession to slowly soften the skin and flatten it incrementally. The flattened document was mounted into a new archival window mat and backboard.

BEFORE TREATMENT

The watercolor drawing suffered from prolonged exposure to ultraviolet light, poor housing and metallic inclusions in the paper support.

AFTER TREATMENT

The watercolor drawing was surface cleaned, metal particulate was removed and it was bathed in multiple rounds of conditioned water to reduce the overall discoloration and staining. The watercolor was hinged into a new archival window mat and backboard.
