different pva I think

It appears that there have been a few PVA's listed as reversible.  The
one you commented on was not the one listed (I don't think) in the Abbey

The paragraph reads: "The reversible PVA adhesive mentioned on p. 57
last year is made by Williams Adhesive and is called WS 3978. CRI calls
it "medium speed" and Williams calls it "fast setting."  Both say it is
fully reversible in water, but neither says whether it is a copolymer or
homopolymer. It is available from Conservation Resources International,
8000 H Forbes Place, Springfield, VA 22102 (703/321-7730)."

Riitta would appreciate any comments about the product.
