Grenadoes consist of a round cast iron hollow ball filled with gun powder and topped with a fuse. They could be thrown like modern grenades or shot out of hand mortars.

This inert replica of the grenadoes found aboard the Whydah and the Queen Annes Revenge has a diameter of 70mm.

They come with either a slowmatch fuse or a powder fuse (a wooden plug filled with an inert gunpowder substitute).
