Apart from the use of siphons or manual flame-throwers called cheirosiphona, special corps of Roman soldiers employed terracotta grenades, in the form of small jars, abundantly evidenced in archaeological excavations. They were called μεσαία kακαβιά or κυτροκακάβια where the former had a bulbous shape and the latter a more cylindrical form.

The Arabs, following the Roman examples, made great use of these weapons. The efficiency of the weapon appears, for example, from the account of the siege of Akka in 1189, given by the contemporary historian Ibn al-Athir. He tells how the Christians exercised their engineering skill and built mighty beffroys. The situation was hopeless for the defending Arabs until a man from Damascus showed up, because he knew how to produce Greek Fire: ‘To trick the Christians he first threw some vesseIs with naptha and other things, which were not set on fire, upon one of the beffroy’s, and it was without power. The Christians...climbed the top of the beffroy...the man from Damascus waited until the contents of the vessels were spread all over. When the moment came,he threw a new pot, which was set on fire. In a few moments the fire was spread all over, and the beffroy was eaten up by the flames. The fire was spread in such a hurry that the Christians could not manage to climb down from the beffroy. Men, weapons, everything was eaten up by the flames.’
