An undecorated black on black LM vessel, likely LB, highly abraded on both the internal and external surfaces. The fragment is restored from 4 sub-fragments. The dominant Black GY1 2.5/N exterior is mottled with Reddish Brown 5YR 5/3, perhaps evidence of firing clouds. The Very Dark Gray GY1 3/N interior is mottled with Gray 5YR 5/1, more likely corrosion. Core band one is actually Reddish Black 2.5YR 2.5/1 (not 10R). While both surfaces are smoothed, the exterior is much smoother than the interior, which is very highly perforated by sand inclusions. Besides the dominant fine sand inclusions, coarse sand particles are also visible in the breaks. Larger particles are occasionally visible in the internal surface. Slight lamination hints in the breaks suggest a slab building process, which perhaps resulted in the differential character of the internal and external slabs. Very high amounts of pyrite particles are visible in both the internal and external surfaces. Breaks are hackly. Light yellowish brown corrosion covers 20% of the internal and external surfaces.
