I routinely heat gelatin solution to 70C (160F) for about two hours
total in two cycles, but gelatin is perfectly capable of gelling.

I also heat pig feet, tails, etc. as well as other gelatin rich parts
in water to 120C at 2 atm for 1 to 3 hours. They size my belly very
well and the solution makes stiff jelly, when refrigerated.
