3. Bowls with broad flange rim formed by the addition of a coil to the 
upper body wall. The rim top is flat or convex, nearly level or 
sloping, with a rounded lip. Mouth diameter 18-34 em.; majority 
24-34 em. (fig. 70-3). 
4, Rounded jars with upper walls insloping to constricted mouth with 
direct rim and rounded or flattened lip. Mouth diameter 20-38 cm. 
(fig. T0-4). 
Rare vessel shapes reconstructed from sherds: 
1. Bowls with nearly vertical walls and exteriorly thickened rim 
(Taurakuli Plain, Common Form 2). 
2. Jars with upper walls insloping, then upturned or slightly everted 
producing a slight neck, ending in a direct rim with a rounded or 
flattened lip. Mouth diameter 22-32 em. 
8. Jars with upper walls insloping to a constricted mouth with an ex- 
teriorly thickened rim, flattened lip (Taurakuli Plain, Common 
Form 4). 
Appendages: Handles. Rarely, vertical loop handles with flattened or 
ovoid cross section, expanding slightly at the point of attachment from 
the dimensions at the center. Size varies from 2.1 cm. wide by 0.9 cm. 
thick to 4 em. wide by 2 cm. thick. 
TEMPORAL DIFFERENCES WITHIN THE TYPE: None observable (Appendix, table 28). 
CHRONOLOGICAL POSITION OF THE TYPE: Tiger Island Plain is diagnostic of the 
first half of the Abary Phase sequence. It shows a steady decline in fre- 
quency, becoming a minor ware in the latter part of the Phase (fig. 77). 
UNCLASSIFIED PLAIN 
PASTE: 
Method of manufacture: Coiling. 
Temper: The characteristic feature of these sherds is the presence of black 
ash or charcoal, with particles ranging from flecks to hunks up to 3 mm. 
Some sherds also have small amounts of finely crushed sherd temper. 
Texture: Fine-grained paste with pinhole air pockets ; temper shows a slight 
tendency to cluster, but mixture is generally good. 
Color: Light- to medium-gray core typical; rare sherds have an orange core. 
Gray-cored sherds are fired orange in a band along both surfaces. 
SURFACE: 
Color: Light tan, cream or orange on both surfaces; occasional gray fire 
clouds. 
Treatment: The majority are eroded, however those with surfaces remain- 
ing show large pits and other irregularities. A few sherds have surfaces 
well smoothed and even. 
Hardness: 2.5-3. 
ForM : 
Rim: Majority direct with flattened or rounded lip; very rarely, everted 
and thickened with a broad convex upper surface. 
Body wail thickness: 3-15 mm.; majority 5-8 mm. 
Major vessel shapes reconstructed from sherds: 
1. Bowls with outsloping to nearly vertical walis, direct rim and flattened 
or rounded lip. Rim diameter 16-24 em. 
2. Rounded jars with upper walls incurving to constricted mouth, direct 
rim and rounded lip. Mouth diameter 8-26 cm. 
TEMPORAL DIFFERENCES WITHIN THE TYPE: None observed in small sample 
available.
