Paste/Temper: Friable sand and grit temper, sand, and angular quartz tempers have all been identified with the type. At the Accokeek Creek Site, temper size ranged between 1 and 10 mm. The regional data summarized by Klein and Stephens (1996: Table 13) indicates a range between 1.5 and 7.5 mm elsewhere.
Surface Treatment: Cord-marked surface predominate, as do cords with a final twist direction of S (defined in the positive impression). Cordage impressions on Accokeek sherds often overlap, the cordage is relatively thick, and the cords generally have been impressed deeply into the clay.
Vessel Form: Manufacture involved coiling and malleating the surface. The conoidal jar with straight walls predominates in Accokeek assemblages. However, bowls are also known (Stephenson 1963: 97-100; Klein and Stevens 1996: 125). Lugs have been reported.
Vessel Diameter: At the Accokeek Creek Site, vessel diameters ranged from 25 to 40 cm. Wright (1973: 31) unearthed Accokeek Creek vessels ranging in size between 25 and 36 cm in zones I and II at Martins Pond (18AN141 ) and between 22 and 65 cm at King I (18AN69). Klein and Stevens (1996: 125) report vessel diameters ranging in size from 17 to 37 cm based on data from At The Falcon’s Landing (18PR131), Accotink Meander Site (44FX1908), and Spessard (44FV0134) sites.
Vessel Height: Stephenson (1963: 100) reported vessel heights of 25 to 40 cm, based on twelve reconstructed vessel sections.
Rim Form: Direct or vertical rims predominate, with slightly everted forms more common than slightly inverted or extremely everted. Both flat and rounded rims have been identified, as have pointed and thickened lips.
Base Form: Stephenson (1963: 100) reports conical to semiconical forms, with rounded bases rarely occurring.
Vessel Wall Thickness: Stephenson (1963: 100) reported a wall thickness range of 4 to14 mm, with 90 percent of all sherds measuring between 6 and 8 mm. Mean wall thickness data summarized by Klein and Stevens (1996: Table 13) fall in this range, with mean values between 6.47 mm and 7.4 mm.
