ON CONSERVING WOODEN NUMISMATIC OBJECTS

Anne E. Bentley writes: "To answer Ron Abler's query regarding how
to handle the wooden objects in his collection, oiling would be the
worst possible thing he could do to them!  In 25 years as conservator
at the Massachusetts Historical Society, believe me, I saw the horrible
results that ensue from such treatment on wooden objects.  These ranged
from the discoloration (usually splotchy, thanks to difference in
grain) to major splits (from introduction of a liquid, forcing open
the grain), to mold (the combination of oil and humidity on wood
creates spectacular colonies under "proper" conditions) to warping.

"Most importantly, once introduced, oils and waxes on wood can never
be reversed.  We have always just dusted the pieces and tried to keep
them in stable relative humidity, to avoid extreme changes in moisture
within the wood.  This has been very effective in maintaining our
wooden pieces.  If you have to contend with a humid climate, you can
create a drier micro-climate by storing your wooden pieces in container
with silica gel packs to regulate the relative humidity.  I hope this
helps Mr. Abler to decide on the course he plans to take with his
collection."
