Wax seals

We have in our collections a number of 17th and 18th century documents with
huge pendant wax seals.  Hey, wax gets old, too, and we're concerned about
further physical deterioration...chipping, cracking, etc.  Does anyone have
any suggestions for how best to manage this?  Are there any particular
considerations for wax preservation?  Among other difficulties, they're
large seals (12 cm or more) and many are attached to large documents, so
boxing or other close packaging isn't the easiest...
