I have heard of hooves/horns being used to make glue.  As yet, I have not seen anyone that can do so without a serious chemistry set, far beyond what any pre-Columbian culture could achieve.  As for antler making glue, I think that is something akin to alchemy.

Thesquirrelslinger:
In TBBB it says that two non-sources of glue are hooves and horn...

I'll stick with hide and sinew scraps  8) for making glue . And I won't back a bow unless I need something short for hunting in tight spots . Short to me is 48" . In my eyes long is 60"

richardzane:
Pamunkey is right about thick pots:
 
 "Pots don't need to be thick to cook in (thickness actually makes them less efficient).

and thick pottery is much more apt to blow up in the firing of them, as thick walls can hold in moisture or air bubbles.

an earthenware pot is porous and will absorb moisture though, so it'd be important to not leave heating glue unattended very long

Not necessarily, iowabow has been doing some work with ABO pottery and has had some luck making a smooth inner surface that is far less porous than simple fired clay. 

He's also figuring out how the chemistry works with the ground shell that he is using to temper the clay.  When I was at his place last week he was showing me ABO pots that had been fired traditionally.  The parts that fired in an oxygen deprived condition were really good and solid, but the stuff that had oxygen available saw spalls and cracking from the shell resorbing oxygen/etc. 

Those so called "primitives" knew their biscuits from their butts!  They busted their humps surviving so that their later generations could sit in front of computer screens and theorize how they survived.
