RE: Gum hardening: top down experiment

Yes, but we are talking about exposing from the back. My fuller explanation
is given in another email that I just posted.
 
But from Marek's description later, it sounds like his case is because of
underexposure, so with that I agree with what you said below.

It's the other way round.

If it is unhardened gum it is so underexposed that it will fall off the
paper.

It might be because the development is not complete, so there is still a lot
of unhardened gum (which contains water). Well, actually even the hardened
gum is soaked up with water at that point, so the water will continue to
develop the surrounding gum. Sort of like if you put a piece of ice on jello
versus you put a piece of ice on gum. The first case will have no problem
whereas the second will make a mess.
