IonRocks Posted October 21, 2016 Share Posted October 21, 2016 So i still collected this massive shell, but it is (like most of the shells I find) in pieces. I need advice on what glue to get, to best repair it. It definitely needs stabilization, and the rock is broken in to multiple parts. So far I've had no luck glueing the sandstone Link to comment Share on other sites More sharing options...
DPS Ammonite Posted October 22, 2016 Share Posted October 22, 2016 Try Super Glue (cyanoacrylate) to glue pieces back on. Try not to use so much that it flows out the cracks. Once the pieces are together use a consolidant like Butvar 76 mixed with acetone to cover entire rock. My goal is to leave no stone or fossil unturned.

Actually, you want to consolidate then glue this way you don't weaken the glue joints by applying solvent to carry the butvar. Also, this will help with the gluing. Sandstone is so porous that it will often suck up the glue so much that you can't get a decent bond. Consolidation first helps with this when using a very low viscosity adhesive such as a cyanoacrylate.
