sturgeon bladder glue
superdav95:
Ive made some natural glue posts before but figured with the new kickstart of the forum i might as well post pics and short vid of my recent batch of sturgeon bladder glue. These bladders come to me raw and whole from a russian sturgeon fish farm in new brunswick. as seen in the pics I scrape the inner membrane with a spoon and cook it over a very low heat in water about half and half. I keep temp to below 60 degrees. this ensures good strong clear glue. This glue if done properly is a premium glue for bows. I normally reserve it for my hornbows. The outer membrane of the bladder can also be very strong glue. I will render this down much the same way but for much longer. about 2 days. I skim off the fat as it cooks down. It is cut into smaller pieces to help it render down better. I will use this 2nd run glue for a mix with my home made sinew glue which will give me a little more working time and enhanced strength. Once i pour it off and strain it through a cheese cloth it’s ready to gel up and set. I use shallow pans and then cut it up into cubes to then dry under a fan. you can see the clear light color of this glue.
Here’s a short video

I keep telling myself I’m going to do this, but it doesn’t seem to happen.
I tip my hat to you sir.

Thanks guys. It’s labour intensive but worth it.

Just curious if that glue is stronger than hide glue and is it waterproof?
Was just looking at your thread and thought I’d ask. Looks like pretty cool and I really like the process of making glues the old fashion way. One of many reasons I like this site is she many things I learn just browsing around and reading other people’s threads.
