Not long ago I had to transport a relatively large size (160 X 110
centimeter), and very fragile charcoal drawing from a private
collection  to a new site for treatment. I used 25% V/V
Cyclododecane in petroleum spirit 40-60. Dirst, before application I
checked that the petroleum spirit would not stain or react with the
paper support. I used a simple hand sprayer to spray the solution on
the drawing. After three/four hand applications the media was
sufficiently protected so as not to leave any black powder stains on
a white blotter.  The drawing was rolled, but not tight, on a tube
and removed to its new site for treatment. The drawing arrived
safely at its new location. After few days the Cyclododecane
evaporated and the drawing was ready for treatment.
