I've build some portfolio boxes with 1/8 plywood glued to pine frames
with regular yellow wood glue. The plywood says it uses a formaldehyde. I
want to store Gum prints, Cyanotype and regular B&W prints in these
boxes. Any suggestions on what I should line the inner plywood surface
with? A paper?
My guess is since formaldehyde is used in some of these processes it
should not effect the prints. But I want them to be safe.
Thanks
Bob
