    Hi guys, friend of mine's family found what appears to be an old cannonball while doing some work on their back garden in ballyfermot (near markievicz park) and gave it to me to have a look at. They have had it a few years and I have asked for further information on where they found it. Unfortunately the bottom of it has been covered with paint by them.

    Just wondering who I should bring it to to have it looked at. Although it appears to be a solid slug, I am thinking it would be best to take it to the guards/army to make sure it is not a potential hazard.

    Any advice on what this is or how to proceed in getting it examined would be appreciated.

    Well first and foremost, although I would agree its probably just a solid ball, I'm really not informed on such things and therefore, if you have reason to believe you should exercise caution then you should absolutely do so.

    Secondly, ring the national museum and ask for the duty officer. As an historical artefact it belong to the NMI already and they should therefore be made aware of its existence. Furthermore they will be in a far better position to advise you on where to go next.

    Its a fantastic find, and it might be that it wont be taken off you, but definitely put best foot forward and call the national museum about it.

    Regarding whether it's explosive or not, Weigh it and measure the diameter... Calculate density, assuming it's iron it should be 7.9 g/cm−3 .. Density would be a lot less if it had a cavity for explosive material.. Also an explosive cannon ball would need a hole in it (possibly packed with some material or other)..

    Is there any chance it could be an old shot put? I guess the museum could clarify this. I have no idea how to distinguish them.
