'This research has shown the diverse use of these unique ceramic vessels'

Ceramic vessels which date back to 11th-12th century Jerusalem could have been used as an ancient version of explosive hand grenades, according to a recent study. Though the containers were originally believed to be used to hold scented oils or for a variety of other purposes, Dr. Carney Matheson, an associate professor at Griffith University in Queensland, Australia, found that a number of the vessels also contained traces of flammable material.
