Paste/Temper: Keyser has a compact paste that is fine to medium textured. Color ranges from an oxidized brown to reddish brown, but dull grayish brown is the dominant color. Vessel exteriors often have a blackened appearance. Interior surfaces are roughly smoothed and are dark gray to black in color. The temper consists of finely crushed freshwater mussel shell that varies from 0.5 to 8 mm in diameter, and makes up 10 to 30% of the paste.
Surface Treatment: Exterior surfaces are cord marked. Most vessels show cord marking applied vertically, but a few have cord impressions that are oblique. Cord marking is predominantly an S-twist, but Z-twist is also well represented in some collections. Manson, MacCord and Griffin (1944) noted that cord impressions were rarely smoothed over on sherds from the Keyser Farm site (44PA0001), but most sherds recovered from the Hughes site (18MO1) and the Moore Village site (18AG43) show signs of partially smoothed-over cord impressions (Jirikowic 1999:2). Sherds from the Cresaptown (18AG119) and Barton (18AG3) sites also show similar smoothed-over cord marking on vessel exteriors (Wall 2001). Smoothed-over impressions normally suggest later ceramics.
Vessel Form: Vessels are large, coil constructed with paddle malleation, with wide mouths and globular bodies. Neck areas are very slightly constricted to straight sided
Vessel Diameter: Vessels measure at the rim 15 to 35 cm in diameter.
Vessel Height: Unknown
Rim Form: Rims are vertical and straight or slightly flaring. Lips are straight to slightly everted, and usually have cord-impressions made either parallel or transverse to the lip’s edge.
Base Form: Rounded bases
Vessel Wall Thickness: Vessel walls are thin; their thickness ranges between 4 to 5 mm with an average of 4.5 mm.
