Reason: Storage
Description: Polyvinyl butyral (Mowital B30H) 10% in IMS was injected beneath the laminations with micro and standard sized pipettes. Any excess resin on the surface was removed with acetone on a cotton wool swab. Laminations of >1mm were also filled with polyvinyl butyral of the same concentration mixed with limestone dust to form a thin slurry. The edges of these laminations were supported with a thin paste of polyvinyl butyral, 20% in IMS and limestone dust. Those areas in which the stability of the design would be improved by cleaning were lightly swabbed with saliva on cotton wool swabs and then rinsed with acetone on cotton wool swabs.
