[Nhcoll-l] [HERBARIA] displaying plants

Wed Jan 11 18:01:05 EST 2017

most coatings and glass additives that are intended to provide UV
protection have a lifespan...they do not last forever.

chances are if those windows have been there for a long time, whatever
protection they provided when they were new is gone or vastly reduced by
now.
