Consolidate lifting pigments and reattach delaminating papers
The six- panel folding screen presented particularly in panel 3 and 4 a diffuse phenomenon of lifting and delamination of some of the paper substrate (overall and towards the margins at the hinging level) as well as a few areas of fragility of the pigments. The red was cupping and in some cases the white was weak and in danger.
One by one each panel was inspected with raking light , marked and prepared for consolidation of both the paper delamination with wheat starch paste and 4% pearl glue to reinstate the weakness of pigments.
the adhesive was allowed to penetrate in and was then pressed through a layer of 8gsm polyester tissue and blotters. The blotters were changed to prevent excess humidity from spreading to other areas.This procedure was followed by accurate rechecking and eventually re-consolidation interventions .
