. . . what a fired ebreek (a traditional Arab water jug) looks like when cut in half? Most folks probably don't. For those who do wonder, well, here you are!
Note the concentric lines that result from the wheel-thrown process. Note how the vessel walls of the body are quite thin, whereas the walls of the neck and the lip of the rim are fairly thick. Note how the color shifts from orange to yellow. Note the slight concavity of the ring base.
The more you look, the more you see!
I found this ebreek section at the Palestinian Institute of Archaeology on the campus of BirZiet University many years ago.
