I should have been clearer. Just trying to several things at once and
none terribly well. I  would like to exhibit an ice core from the
Antarctic, the sort of cores that scientists use to extract
historical information about the weather for example. I'm trying to
find someone who may have solved some problems related to exhibiting
like fogging of the view window.
