I have been experimenting with using cyclododecane on a large scale
in architectural applications, primarily in wood conservation and
treatment.  I have found that the material is ideal for temporary
adhesive uses.  I have been using it as a stabilization material
that will allow me to remove fragile, deteriorated architectural
elements from the building in order to consolidate and/or repair the
piece. Currently, a conservator at the Metropolitan Museum of Art in
New York is doing a great deal of research on broader applications
of cyclododecane.  I have been in close contact with her during my
experimental research.

For the record, cyclododecane is a material that sublimates at room
temperature over the course of one to two weeks (under exhibition
lights, it may sublimate more quickly).  Once sublimated, there is
no residue left behind. The material can't help but be reversible.
Contrary to what many may think, cyclododecane is a bit stronger
than conventionally thought. I have also used this material to
consolidate in-situ broken architectural terra cotta ornament in
order for its removal for repair.

If you don't have any at your disposal, the only place I know to
find it is in New York City at Kramer Pigments.  Melt the crystals
over a protected heat source and apply it straight, don't dilute it
in a solvent. The material is highly flammable, so use care.  It
also cools very quickly.  Experiment with it first.
