True, but slides can last quite a while... I just finished cataloging
some serial sections done in the 1890's.  The labels were written
in india ink, but the paper they were on was crumbling and lifting
off the slides.  The sections themselves, however, were still in good
shape... staining still good, sections untorn... just a slight drying
of the medium at the edge of the coverslip.  Wish I knew how they
did it--- they look better than some of the slides we purchased 2
years ago for the teaching collection!  ;-)
