I'm quite surprised Scott- I just don't see how thoroughly saturated protein glue could not be a gel and thus longer a functional adhesive- the two are mutually exclusive. Collagen will absorb a huge amount of water, and becomes basically 'Jell-O'- it's how I clean my glue pot: add an equal amount of additional water to any leftover glue present and it becomes an easily removed, rubbery mass in a relatively short period of time. If your experience was that the glue was still quite functional, it either couldn't have been saturated or something else is going on. With PVA I can understand, but not rabbit glue unless it's very different than bovine hide glue. Now I really want to try this all again to see if I missed something significant...
