Tubulus in shape of a rectangular box with rounded corners. Two narrow
sides pierced with circular holes (Diam. 0.020) for lateral ventilation. Thin, sparse
patches of mortar across surface mark attachment to adjacent tiles and walls. Two
jagged seams along lengthwise edges on one of narrow sides reveal that flue tile
was made by wrapping sheet of clay around a former (wooden beam?) and then
closing gap by patching in smaller sheet.
Preservation description
Intact with slightly broken edges. Slight erosion on one side but otherwise well preserved.
