CEBAMICS 



Total sample: 463 sherds. 

 I. Ch'oup A (sample: S19 sherds, S5 rim sherds, portions of S5 vessels). Plate 

 27, c-f, j, k. 



A. Paste: 



1. Temper — fine grit or sand with two varieties of inclusions. 



a. Pebbles of quartzite, both angular and waterworn. 



Range of diameter : 0.5-1.0 mm. 



b. Large, angular black crystals, probably hornblende. 



Range of diameter : 1.0-3.0 mm. 



2. Texture. 



a. Surface — medium coarse. 



h. Core — dense and homogenous in sherds containing grit aplastic, 

 otherwise friable and somewhat lamellar. 



3. Color. 



a. Exterior — gray black — a minority of sherds are wholly or par- 

 tially oxidized to a variable red-orange color, firing clouds 

 infrequent. 



6. Interior — identical with above. 



c. Core — similar to cortex except in heavily oxidized sherds where 



a "spotted" or variable coloring is encountered. 



B. Surface treatment: 



1. Exterior — cord-wrapped paddle impressions, covering entire body of 



vessel. Vertical treatment is most common, but criss-cross of hori- 

 zontal variants occur. 



2. Interior — well smoothed, finger and tool marks indicate horizontal, 



annular manipulation. 

 C Form: 



1. Lip — two variants are present: 



a. Narrowed and rounded, beveled on the Interior surface toward 



a rounded or subapical termination (0.46 of sample). 

 Range of thickness : 1.5-3.0 mm. ; mean, 2.2 mm. 



b. Flattened, a definite internal fiange occurs in one case, external 



flanges in two. A rolled lip is present In a single example. 

 Range of thickness : 3.5-8.0 mm. ; mean, 5.6 mm. 



2. Rim and neck — incurved, a single example, that of a modified "raised 



corner" variety (pi. 27, /, fc) (Baker et al., 1941, p. 20; Bennett, 

 1945, p. 81; Schoenbeck, 1946, p. 36), suggests an outsloping 

 emergence. A vertical rim is also present in a single case. A 

 marked thickening of the rim at the shoulder juncture occurs in 

 0.11 of the sample. 



Range of thickness : 4.0-8.0 mm. ; mean, 5.5 mm. 



Range of height : 22.0-50.0 mm. ; mean, 32.8 mm. 



3. Shoulder — smoothly curved. 



Range of thickness : 3.5-11.0 mm. ; mean, 6.2 mm. 



4. Body — probably globular. 



Range of thickness : 2.5-8.0 mm. ; mean, 4.4 mm. 



5. Base — no data. 



D. Vessel shape: a single shape is present — a wide-mouthed jar with a 

 globular body. 

 Estimated mean height: 190 mm. 

 Estimated mean diameter : 160 mm.
