Thanks for the swift reply Bonjoy. The flake- or more apt might be shield- is really large >1m square- and is fully intact, it just booms. It’s also nearly 15m up a major grit crag.  I think you would have to crowbar it off and have no clear idea where it would fracture or how to secure a thing of that size.

A mix of resin and  mortar sounds interesting. Where could you get that from please?

Hallo. Can anyone recommend the strongest resin to use for glueing granite? I pulled a small chickenhead off a project and would like to reattach it.

Pure Epoxy is the best option for strength. It has a longer drying time than the alternatives, but worth it if you need the extra strength.

Got a couple of questions about glueing limestone holds. I have always used this stuff for fixing loose holds

https://www.screwfix.com/p/easyfix-kem-psc-380-ef-polyester-resin-380ml/1245j.

It's worked very well, but wondering what is best for holds that have come off entirely. Pure epoxy is mentioned above, would that be something like this?

https://www.screwfix.com/p/no-nonsense-2-part-epoxy-adhesive-tubes-pale-yellow-30ml/111KH?tc=EH7&ds_rl=1249416&gclid=CjwKCAjwxr2iBhBJEiwAdXECw7KbjCBpHsufoGjKBxjZtNrD80ESE105OSTzqxM9mk7ev5sCoqZHqRoCVh0QAvD_BwE&gclsrc=aw.ds

I also want to sure up a hold that is slightly wobbly, but the fractures around it are very small and needs something quite low viscosity to get in there. Would something as simple as super glue do the job here? TIA

Yes, that sort of epoxy should do the job. It's also available in full size gun resin tubed.
I,ve used superglue down hairline cracks and thin flakes. It sometimes works well. It can get in quite deep due to the capillary effect and bonds quite well if its a very thin crack and both sides match.
