I found a strange source of Isinglass, never tried (caveat):

Dusan, why do you think it does not work as glue or glue add on. Does it contain silicic acid or some other additive making it unsuitable as glue?

I dont want to put these words in Dusan mouth but my best guess is that this product contains god knows what...i am not sure about powderish things, since they have broken up bonds in long molecules, the ones that need to rebond by moisture and heat...? therefore I double agree with Dusan

An old post is coming up. Some information about issinglas

Issinglas/fish bladder consist of pure collagen. These are the swim bladder of fishes respectively only from sturgeon. The fish bladders are cleaned, dried and beached fish bladders. These are put together during the drying and then cut into white leaves. The Isinglass is directly imported from the big sturgeon farms. They are dried in their original condition, lightly yellow and full of high-class collagen. An increase of the adhesive power is impossible.

Issinglass is also used for the clarification of high-class wines. Also here it is to say, the more the issinglass is a high-quality product, the more you can decrease the dosage. Especially in Chinese cooking, Issinglas is used for delicious soups and dressings - hen haoche!

Applications:
Fabrication of musical instruments, fiddlesticks, clarification of wine

For bow making: the core/horns I coat with 5-7 thin layers of issinglue, then I start mixing hide glue (2/3) with issinglas (1/3) for the last 2-3 layers before clamping the two elements together. This mix is very efficient in using yew cores - So far I processed 5 yew cores - no failure, no delamination (the same for the other maple cores...)

Thanks Reto! for ellaborating, even more now we have been talking about yew...you clarify your proportions...is there a reason for the mixing with hide glue? any reason you reached this proportion, or just trial and error?

Thnak You Reto

Try and error, while coating my first hornbow (with yew core) I slopped the pot with issinglass, but fortunately I still had some hide glue, therefore I mixed the two and my experience was very positive since then....

Reto and all ,
do you have a problem if you take full advantage isinglass of gluing horn / wood (acer tataricum)? I have three cores bonded with isinglass but I do not know yet the outcome.

Friends, please read older posts in Atarn . There is all about glues... Its imposible answer again and again ... in the same "new"question.

Thanks Dusan for the hint! Appreciated.

Well, in short - this clearing isinglas is only solution from pure glue./often 1%/ and soaked in vine acid...
