Since your concern is about the safety of pest-eradication methods
such as freezing for composite polychromed, varnished, gilded or
lacquered material, it may interest you to know that I am conducting
my MA dissertation research on this subject. The dissertation should
be completed and submitted by October, 2001, and the main types of
objects to go into experiments will be ethnography and natural
history specimens.

If you, or anyone else reading this message, has any particular
knowledge of other research on the same subject, it would be very
interesting for me to know. The literature I have collected so far
seems to show a gap in the research of effects of pest-eradication
on object materials, especially where composite objects are
