Pen and iron gall ink tracings in deteriorated condition by the American painter Washington Allston (1779-1843) were lined with a nylon web prepared with a sprayed-on poly(vinyl acetate) film. The linings were heat-sealed to the tracings with a tacking iron, on a dry mounting press, or on a vacuum hot table. Another application, the lining of a fragile, double-sized Italian drawing in pen and iron gall ink, is also described. -- AATA
