First attempt at making hide glue...

[Cloudfeather]

This is my first shot at making hide glue. I simmered scrap sinew and tendon cases for about 4 hours, then reduced it for another hour or so. This is what I've got. I cut it into little gelatin squares and set them on paper towels. Do they look about the right color? Also, do I have to keep drying and reducing the size or can I put them in a container and freeze them? I've heard mixed ideas so I just wanted to see what everyone thought. Thanks.

Howdy,  It looks good to me.   If you're planning to use the glue anytime soon, I'd just freeze it.   Once fully dried it will store well in a bag on the shelf, but will take longer to use, as it will need overnight soaking, before being heated up.   Ron

Thanks. Yea, I plan on sinew backing a bow with it within the next week or two. Can it be frozen or stored once it's reheated if you keep it under 140? Or is it a one shot kinda deal?

It can be reheated a few times without losing strength. I heat it in a cool whip container in double boiler fashion, then when I'm done and it's cooled, I put the container in a 1 gallon ziplock freezer bag and put it in the freezer until next time.

Make sure it doesn't stick to the paper towels as it dries.

Good air flow is the key to drying it well. Next time heat it for around 10 -12 hours to get the most from your scraps but keep the temp low.
