Hello, I have a couple of questions. Are there any ways of sealing new wood so that none of the acid or anything gets out of it into the interior of a case? I was thinking of making a couple of new, small cases with some UV blocking plexiglass. What about a calk-like material that is archival to go between the pieces of plexiglass? Is there such a thing? Also, I am part of the registrar's comittee and cannot seem to get onto their listserv. Does anyone here know how to do that? Thanks.
