Reason for treatment
Clean feathers. Remove folds and creases. Repair skin. Leave threads intact.
The whole of the object was dirty, notably the feathers, with areas of more intense dirt. Moth remains in places. The white feathers at the edges had turned grey. The back of the object required repairs since the skin had holes and was cracked and torn in different areas. There were major and minor distortions; lines where the cloak had been folded, and creases and folds elsewhere, especially near tears and breaks. In some areas feather shafts were loose and poking through the back. There were loose stitching threads around the perimeter of the cloak.
Back of cloak cleaned with a Wishab sponge (vulcanized latex,filler) gently manipulated over the soiled surfaces. Residue was vacuum cleaned away. When cleaning was finished,the object was relaxed by humidifying above a layer of Goretex. The Goretex was dampened on the felted surface and allowed to humidify under plastic sheeting. The Goretex was then removed and the cloak aligned and weighted. Allowed to dry. Repairs were then carried out on the back of the object. After experimentation with other backing materials (non-woven polyester), dyed Japanese kozo paper and 10% Mowilith 50 (polyvinyl acetate) in acetone as adhesive were used to secure the loose shafts of the feathers from the back and to support other tears as necessary. The ultrasonic humidifier was used for local crease removal. Once all repairs were carried out to the back, the feathers were cleaned. Applied Industrial methylated spirits (ethanol,methanol) to each feather with a sable brush, removing dirty solvent with blotting paper. Dried, preening in a stream of cool air to fluff up. Only the most discoloured areas were cleaned, there being insufficient time available for complete cleaning.
