Ever used a meat thermometer on a turkey? same principal, only one turkey (the antique) remains pristine. One more mask comment. While anoxia may or may not be your choice of treatment, storage in very low oxygen conditions will also prevent the development of mold on the masks while they are damp. js Jerry Shiner Keepsafe Microclimate Systems 800 683 4696 www.keepsafe.ca <http://www.keepsafe.ca/> [email protected] Specializing in the design, procurement, and installation of environmental control systems in museums and archives. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Appelbaum & Himmelstein Sent: Monday, November 26, 2012 10:50 AM To: [email protected] Subject: Re: [pestlist] freezing damp wooden objects

I am not certain about the effects on wood-borers in particular or the timing. Others on the list can be more specific about this.

They would then be able to be frozen without incident. Be careful of any adornments on the pieces and be sure freezing wouldn't affect them.

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.
