On the quilt history listserve there is discussion about what to seal
wooden items such as valences that may come in contact with quilts.
I originally posted:
As any wood can off-gas, be sure that the quilt is not in contact with
the wood. Better yet, acquire the wooden box two weeks before use
and
seal it with two coats of alkyd-based
polyurethane.
See:
Conservation Concerns: A Guide for Collectors and
Curators, Konstanze
Bachmann, ed., Smithsonian Institution Press, 1992,
p.74.
Then I posted:
I should have added that there is a difference between storage and
display fixtures/furniture. For a home display I'd go with the
recommendations for museum storage requirements unless you are scrupulous
about
rotating your quilts. All too often a quilt is displayed in
the home,
and 4 years later it's still there.
For
information:
Northeast Document Conservation Center in Andover, MA has a

website for the Regional Alliance for Preservation.& nbsp; Found
there:
Materials Used in Storage:
"Not all institutions can afford
specially fabricated storage units or
even steel shelving. Existing
equipment often has to be used or simple
wooden structures built. Solid
wood is better than plywood which
contains harmful formaldehyde resin.
Oil-based paints and polyurethane should
not be used to seal the wood.
Shellac and water-based acrylic paints
(not latex) are safer."
Now there seems to be contradictions in my recommendations,
however. The NDCC article includes the following:
"The most readily available sealant that is recommended at this time is a
moisture-borne polyurethane. Many kinds of polyurethane are available.
Oil-modified polyurethanes are the most common. However, oil-modified
polyurethanes, oil-based paints, and other products that contain oil or alkyd
resins should be avoided. [my emphasis] Only moisture-borne
polyurethanes are recommended. Unfortunately not all moisture-borne
polyurethanes on the market are safe for use. Also, formulations often change
without notice. For these reasons, the polyurethane selected should be tested
prior to use to guarantee its acceptability. Contact a
preservation professional for brand names of moisture-borne polyurethanes that
are currently being recommended and begin testing with these. Because these
urethanes do not completely prevent the escape of volatiles, choosing
low-emission wood products is of critical importance."
Could I please get some help for suggestions for sealing wood
fixtures used to hang quilts?
Thanks very much-
