Loris,
A note on the bottle
says "post plasticezed neutral pH ply vinyl alcohol).
perhaps one can mix a PVA
solution from polyvinylalcohol that can be bought. I suspect that there are
other additives in the Gamblin product, but they might not be all that
relevant to the gum sizing.
I also have to add it is so simple to just
take some solution from the bottle, add water and brush it on paper, no
additional chemicals, no mess.
