My museum recently acquired many painted wooden objects from Papua New Guinea. They are heavily infested with different woodboring insects, which we would like to eradicate by freezing at -30°C. However the objects arrived in a damp state (wood humidity 16-18%), and cannot be dried prior to the treatment. Will there be substantial damage due to the formation of ice inside the wood? Smaller objects have been frozen to -20°C without apparent damage, but I am still uncertain. I'd be very greatful for any help and advice! - - Leonie Gärtner Dipl.
