The grenade was an inner can of explosive with an outer can of metal fragments or bearing balls. The heavier pattern No. 9 grenade contained more high explosive and more metal fragments.
The fuse was ignited by a friction device or a cigarette.
Initially when demand for grenades was at its greatest, engineers were encouraged to improvise their own grenades from the tins containing the soldier's ration of jam, hence the name. Incidents with the improvised form and the supply of superior grenades led to official withdrawal of the design.
Jam tin grenades were used as booby traps by ANZACs, by rigging it to a pressure trigger and leaving it under a body or other heavy object to keep it unarmed until it was disturbed.
During the Siege of Kut in Mesopotamia (Dec.1915–Apr.1916), the Royal Engineers in General Townshend's force improvised jam pot mortar shells to be used with equally creative mortars devised from the cylinders of a Gnome 80 hp (60 kW) rotary engine (credit to Capt. R.E. Stace, RE).[1] (The engine came from a Martinsyde S.1 scout plane, likely damaged or otherwise unable to evacuate.)[2]
