Ca. 900-1100 AD.A cream-coloured "Greek fire" hand grenade comprising a domed lid and a biconical body decorated with linear, circular, and rhomboid motifs, which tapers into a pointed base. It is believed that vessels such as this one contained an incendiary agent known as "Greek fire", which, since it was impervious to water, made these vessels invaluable weapons in naval battles. Unfortunately, the exact composition of the Greek fire is unknown. However, scholars posit that the mixture was composed of pine resin, naphtha, quicklime, and sulphur.
