[NHCOLL-L:4584] HgCl2

[Gegick, Patricia, DCA]

Dear List,
I have a beautiful bird egg collection from the early 1900s.  On the
listserve this past year was a reply stating that early bird egg
collections were most likely treated with "corrosive sublimate" which is
mercuric dichloride, HgCl2, I believe.  Does anyone know if these eggs,
which have been stored in a closed, specially-made wooden box, give off
any Hg gas?  I am concerned about displaying them during collections
tours. Also, does anyone know how they can be tested for presence of Hg?
Thanks.
