This type of red, gritty pottery with small yellow 'halos' produced by lime is named after a village in northern Bahrain. It is often decorated with raised ridges, either plain or chain-like, and was used from c. 2200 to 1700 BC In the UAE over 600 pieces of Barbar red-ridged pottery have been recovered in excavations at Tell Abraq, and smaller quantities are known from Kalba. This ceramic evidence for ties between the two regions supports the view that Dilmun - ancient Bahrain - and Magan - the UAE and Oman - were in close contact at the end of the third and beginning of the second millennium BC Barbar pottery has also been found in large quantitites on Failaka island, Kuwait, which was established as a northern outpost of Dilmun c. 2000 BC, and at a number of sites in eastern Saudi Arabia.
