Hi Pablo,
welcome :-)
I am wondering why you want to peel off the emulsion off paper ? To
reuse it to coat canvas or similar ?
You can get "liquid emulsion" which you can use for that.
Also peeing papers is a bit ricky because I think (i am not sure about
Baryt/fiber papers) hat for papers the emulsion is also actually
"layered" with an accelerator/devloper layer on top - at least for RC
papers so that they devlop faster like in machines.
So peeling it off you need to be very skillful in roder not to upset the
order of the emulsion lyers.
I might well be wrong in that the developer/accelerator (as AGFA used to
call it) is actually dispersed within the emulsion, btu I always thought
it was on top.
B/W Film emulsion will peel off if you leave it in water for a while,
but you might then get some of the anti-halation dye with it. So you
should rinse beforehand and then do the "peeling off" rinse.
Of course modern b/w films are also multi-layer so a similar caveat like
above applies.
Just a thought or two.
Love,
Snoopy
