I believe Tom Strang wrote up the procedures, probably in Collections Forum. The set up for the branch (is this accessioned?) is to wrap it in black plastic (polyethelyne) leaving some air space. Black plastic will absorb the sun. The roof at RISDI is flat and dark with metal. It should get hot enough - but you might want to put a data logger or thermometer out there to make sure. In the past we have used a simple indoor/outdoor thermometer - the kind with a probe that can go inside the plastic container, next to the object. It would be ideal if you could measure the interior of the wood - but that is not always possible. The critical temperature is 150 deg.

When you say "monitor the temp" if the birch logs are in black plastic - what do you mean exactly? I have never done this type of treatment before but for various reasons we have to do it this way on these birch props this time. Are there any caveats with the black plastic treatment method? Best, Ingrid P.S. Should we talk on the telephone this week about teaching conservation? I am available all days this week... -----Original Message----- From: Gretchen Anderson Sent: Aug 4, 2008 12:58 PM To: [email protected] Subject: Re: [pestlist] What do you do with an 18" potentially infested tree branch? Hi Ingrid, Depending on its length a walk in freezer or freezer truck would work well. Just make sure that you wrap it well to reduce RH shifts. Another option would be heat -- if you have a large space (tarmack is good or flat roof) that gets a lot of sun, you could wrap it in black plastic and monitor the temperature. Or, if you can find a kiln used for drying lumber. We have done that in the past.

I understand the tree branch to be residing in an outdoor car port. The artist would like it exhibited with her fortunately inorganic glass works. Any suggestions? I was thinking along the lines of a freezer truck...any other ideas?

The equipment is VELOXY (VEry Low OXYgen) and it is described in our web site www.rgi-genova.com take a look at the references for VELOXY and consider how many historical and artistic collections have been saved against the process of deterioration due to insect pests.

We will be absorbing the collections of a smaller, nearby historical society into our collections in the near future. The housing for the collections was far from ideal and we, of course, want to treat all the items before they are housed with our permanent collections. The collections run the spectrum from documents/photographs to large home furnishings. We have opted to treat these items by freezing them. We have read the literature on the freezing process and understand it in theory, but would very much like to speak with someone who has had first hand experience with it (especially when dealing with hundreds of objects made from various materials, some made of composite materials like furniture). If you are willing to talk with us, please let me know. Thank you, Steve Lucht Collections Assista nt/Site Supervisor Dayton History 937.299.2722 937.293.2841 Spam Not spam Forget previous vote ------------------------------------------------------------- To send an email to the list, send your msg to [EMAIL PROTECTED] To unsubscribe from this list send an email to [EMAIL PROTECTED] and in the body put: "unsubscribe pestlist" Any problems email [EMAIL PROTECTED] Spam Not spam Forget previous vote ------------------------------------------------------------- To send an email to the list, send your msg to [EMAIL PROTECTED] To unsubscribe from this list send an email to [EMAIL PROTECTED] and in the body put: "unsubscribe pestlist" Any problems email [EMAIL PROTECTED]
