A comprehensive study of the typology, chronology and possible provenance of the Chocolate-on-White wares was made by P.M. Fischer in 1999 based on material from the settlement of Tell Abu-al-Kharaz in the Jordan Valley.
[1] In 1989, a Swedish team under the direction of P.M. Fischer started excavations at the settlement of Tell Abu al-Kharaz in Jordan Valley, where Chocolate-on-White Wares had been found.
Ten seasons of excavations (state 1999) produced 347 stratified vessels, which were included within the Chocolate-on-White Ware group as satisfying a number of listed criteria.
Chocolate-on-white ware has been found at sites in Lebanon, Israel, Jordan and Palestine; there is no confirmed find of such pottery on Cyprus or in the Aegean.
