Core Color: Dark gray to light gray.

Carbon Streak: Fairly common.

Temper: Abundant fine quartz sand; opaque angular fragments rare.

Surface Finish: Bowl exteriors are scraped, with the marks usually very noticeable; sometimes polished; interior bowls and exterior jars: usually more smoothly polished than exterior surface of bowls; the interior surfaces of jars are scraped, with the surface almost always compacted; rarely thinly slipped.

Surface Color: White, usually with slight bluish-gray tint.

Forms: Bowls and jars.

Vessel Thickness: 3.6 to 5.8 mm; jars: 3.5 to 5.8 mm (bowls).

Decoration:

• Paint: Black.


• Pigments: Carbon.


• Design: Confined to bowl interiors and jar exteriors; no rim decoration; bowl bottoms and jar bases undecorated. Patterns: rectangular, triangular, sometimes curved panels containing diagonal or vertical narrow line hatching; rectangular panels almost always much greater in one direction than in other; width of hatching and framing lines usually the same, varying from 1 to 3 mm, framing lines occasionally as wide as 4.5 mm; individual hachure vary considerably in width, spaces between hatchures about equal to width of hatchures; hatchures occasionally wavy; design often begins just below rim with narrow border line; panels may begin at rim or be pendent from connecting line just below rim; rarely any other motif in design; treatment bold, uneven, often sloppy with intersecting lines overlapping as in Kana-a Black-on white.

Comparisons: Polacca Black-on-white has bolder hatching, less regular in execution; panels cover larger areas, less elongated in band form; spaces between hachure wider than hachures themselves; hatching usually combined with solid elements; framing lines usually wider than hachures. Padre Black-on-white has dark gray paste; temper usually white angular fragments; surface heavily slipped and well-polished; paint usually denser. Gallup Black-on-white has similar designs but with mineral paint.

Other Names: Black-on-white Ware, Proto-Kayenta Black-on-white, Black Mesa Pueblo II Black-on-white, Virgin Black-on-white.

Oppelt (2007:79): Dogoszhi Black-on-white (AD 1064-1200) This type is named for Dogoszhi Biko a tributary of Tsegi Canyon. Bowl interiors and jar exteriors are usually more smoothly polished than bowl exteriors. This type is rarely thinly slipped. The black paint is carbon and the temper is fine quartz sand. Forms of Dogoszhi are bowls and jars. Designs are on bowl interiors and jar exteriors. Bowl bottoms and jar bases are undecorated. The common layouts are rectangular, triangular or curved panels containing diagonal or vertical narrow line hatching. The width of the hatching and framing lines are the same. The design often begins just below the rim with a narrow border line. There is rarely another motif in the design. The treatment is bold and sloppy with lines running over at the junctures. This type was traded over a wide area of northeastern Arizona.
