So i was prepping the little Ammonite and it break suddenly while doing the preparation. I tried to use superglue in the fossil to put back together the rock and the super glue falls covering my fingers and part of the fossil. I dont know how to clean it, I tried removing the super glue but it was impossible Now the Ammonite lost plenty of ribs in the good part. I will try prepping the other size. But im very sad right now

I have sometimes had difficulty dispensing small amounts of glue to the right place. Especially superglue can be so thin that - if you try to secure a small spot with glue during preparation to prevent flaking - too much glue is applied, which of course runs immediately and you have difficulties removing the excess glue later. I have now bought a (used Eppendorf) dispenser / pipette, which biologists use, for example, in genetic engineering. With the dispenser, smallest amounts can be dosed safely - the amount of my smallest pipette can be varied between 2.5µl and 0.02µl (i.e. only 0.00002ml !) via the adjustment wheel. First set the desired quantity with the setting wheel, then press down the setting wheel and suck the adhesive into the pipette when releasing the setting wheel. To dispense the adhesive, press the adjusting wheel down again. The part is designed for one-hand operation: Press down, dip, release to suck in the glue, and press again to empty. The superglue does not come into contact with the metal parts of the pipette - a disposable plastic tip is used (1000 pieces cost under 10US$).

For years I have been fighting the tips of Paleobond bottles getting clogged as well as the caps getting glued on eventually. I exacerbate the problem by buying my Paleobond in the largest possible container to lower cost and then refilling my 1oz bottles. I believe I have solved the problem. I rinsed out and thoroughly dried an empty white glue bottle and filled it with Paleobond. With the top open all the way, no pressure is needed for the glue to barely dribble out of the tip. You can close it a little and use some pressure to control the flow. I did this last week and have used it several times with no clogging issues and there is enough space between the bottle and the twist cap that the glue doesn't seem to bond the two at all after use.

Hello, What are the thoughts and recommendations on repairing fossils broken in many pieces. I've mostly used "super glue" cyanoacrylate in the past. The one advantage is that the thin glue allows the fragments to fit together easily. The other advantage is that the first pieces glued stick together quickly and firmly so as to move on to the next of several pieces that need to be added to those first pieces. The big disadvantage is that it is permanent and can't be adjusted a few minutes after gluing. The other problem I've found is that superglue mistakenly applied on the face of the fossil can be unsightly. Are there other glues that would be superior to gluing together a very fragmented piece??
