sturgeon bladder glue

Ya mike it’s stronger and more water resistant.  Put another way it’s more resistant to moisture absorption then regular hide glue.  There are different grade of hide glue too so it depends on the strength you get.  It varies a bit.  I normally use the 192 strength for sinew application.  I have tried the 256 strength too but it gels super fast so what I’ve done is mix this with my sturgeon glue and had very good results with it.  The sturgeon stuff is likely more in line with the 256 strength hide glue but with much slower gel time.  I’ve found its gel time is about double which is great for those complex projects that require little more time to do.  The other way around this is to have a radiant heat source aimed at your work to keep it from gelling too fast.  I use straight sturgeon glue on my horn glue up as it give me a good amount of time and superior strength.  It’s hard to get so when I get it I reserve it for special projects only.   This being said I have done hide glue horn glue ups just fine with the 192 stuff but I would hear cracking noise upon first bracing the bow.  It scare the hell out of me but all was good.  I do not hear these noises with the sturgeon glue.  Not sure why exactly but maybe it is more flexible too.  Cannot confirm this is indeed the case but it would seem to be the case for me and what I’ve observed.   It’s a pristine glue for sure but not entirely necessary for sinew applications in my opinion.

Looks great, Dave.  I'm still at the Knox gelatine stage of my hide glue journey.   ;D  I have a whole tub of elk/bison sinew scraps that I plan to cook down one of these days, just so I know how to do it.  Fish bladder glue is definitely several levels up.
