Cannonball question

[P14]

Thanks for all your help and an interesting discussion. Mystery solved, and I’m relieved I don’t have a shrapnel shell/ grenade.
As far as I understand, provided black powder is kept dry and sealed from the air there’s no reason why it won’t work, even if its 300 years old. I don’t think it decomposes by itself.
Nice collections. Fernando, what is your fuse in the acrylic box made of? Is it like hemp match, the sort used for matchlock musket?

Some very nice projectiles there Will & Fernando.

I was unable to post photos of my collection yesterday, trying again this morning:

I wasn't clear enough. The clay grenade wooden fuse was shown in the bottom of post #7.
The item shown in recent post #23 is in fact a portion of XV-XVI century haquebut matchcord 'Luntenstrick', also offered by the late Michael Trömner (deceased illustreous member 'Matchlock').
