Having seen the retablo in question, cyclododecane is an attractive
way to go, given the delicacy of the surfaces. However, in recent
tests, there is reportedly some residue left on glass slides after
sublimation of cyclododecane.  Sara Caspi and Emily Kaplan spoke
about it at the objects specialty group session at AIC this year, in
the context of stabilizing archeological ceramics.   Still, it may
be the least of all the possible "evils" with regard to
preconsolidation/stabilization, and testing would be interesting.
