As you peer straight down into Abu Ali's ceramic kiln you see the firebox at the bottom. The view is deceptive. The distance between the "manhole" at the top of the kiln (where I'm standing) and perforated firebox is about six feet. Bone-dry vessels to be fired are carefully lowered through this hole and stacked inside. Note the few "melted" ceramic fragments on the bottom. A metal lid will seal the "manhole" when the the firing begins. The fire will be controlled through the firebox door on the side.
This traditional installation is located in the refugee camp at Aqabat Jeber, just outside of Jericho, Palestine.
