Sheet XVI/9 was adhered to a secondary support which was pasted using animal glue along all edges, covering approximately 10mm of the edge.

A steam pencil was used to remove the mount to ensure that the application of moisture was controlled. Poor removal techniques can cause skinning of the paper's surface, lifting off the top layer.

Removal of the secondary support from XVI/9 was problematic as the ink line is extremely sensitive to moisture; this state is known as fugitive.

Animal glue reactivates with heat making the separation of mount from drawing possible. The use of the steam pencil ensured that both the drawing and mount were removed without causing any damage. The mount took several hours to remove from the back of the drawing. This can also be seen in case study X/4 which also shows the deterioration of animal glue.

The mounts with the lines made by Lord Burlington that were removed were kept in an inert polyester enclosure (melinex®) and stored with the drawings because they represent part of their history.

All of the other Palladio drawings for the Palladio 500 exhibition also required new mounts as they were heavily discoloured, fairly brittle and not at museum standard.
