Hi Wayde,

I see your point now, and I apologize for misinterpreting you (I thought you
were doubting the real effect of hardening at all).

I too had the question about whether the dry hardened film is in fact more
abrasion resistant than the dry unhardened film (gelatin or gum). For
example, if I compare a dried watercolor painting with a dried gum print, I
am not sure if the gum is more resistant to abrasion than the watercolor.
Maybe theoretically it is, but they might be close that it doesn't make much
practical difference.

The point that I was making in my post about hardening offering protection of
a print is that it at least protects the print better from getting re-moisted
either from water or in some case moisture from the atmosphere.
