Colour Lithograph with Ink Inscriptions

Family Record (20” x 16”)

Mixed media artifacts can be complex and challenging to treat. This family record required de-acidification, and lightening of the paper support and overall flattening to reduce disfiguring planar distortions. Before conservation treatment could begin extensive solubility testing was conducted on the ink inscriptions, each individual colour used in the decorative motif, and the printed gold background. This stage is critical because what might be a safe solution to use on one media may be destructive to another. After a suitable course of treatment was determined the family record was washed, de-acidified, artificial light bleached, lined to a sheet of Japanese tissue to reduce planar distortions, and retouched using watercolour pigments.
