Upper Egyptian Marl Common ware is made from calcareous clay native to Upper Egypt and its eastern desert (Herbert and Berlin 2003, 27). This was an all purpose ware that potters used for almost every form—from tablewares to kraters, various types of cooking pots, stands, basins, and jars. Vessels are common at sites at Upper Egypt and are known in smaller quantities at sites in Lower Egypt.
At Coptos, it was identified as "Light red marl" and first appears in the late 4th century BCE, in the earliest Hellenistic assemblages. Vessels of red marl continue to occur in Roman levels, though the proportion of this ware to others is significantly lower in the later periods.
The Theban region, and particularly Medamud, is certain...
Upper Egyptian Marl Common ware is a hard, very gritty and slightly micaceous ware, fired from light brownish pink to dark red. It is coarse with many rounded and subrounded moderate sized black, grey, brown, and angular white particles, large fragments of chaff, and many angular voids. Potters occasionally applied a white slip (perhaps a salt wash?) to vessel surfaces. Full firing is rare; there is almost always a wide light grey core.
