Pinto Polychrome is the earliest type of polychrome Roosevelt Red Ware. This type is found along the Mogollon Rim, in the Tonto Basin, the Sierra Ancha, the Globe Highlands, the San Pedro Valley, the Point of Pines area, the Kinishba area, and in the Upper Gila Valley, Arizona.

Archaeological Culture: Salado

Date Range: A.D. 1280-1330.

Construction: By coiling.

Firing: In an oxidizing atmosphere.

Core Color: Brick-red, tan, gray to black.

Temper: Moderately abundant fine water-worn sand.

Surface Finish: Exteriors slipped red; interiors slipped white.

Surface Color: Exterior: red; interior: white.

Forms: Bowls only.

Decoration:

• Paint: Black on white or red slip.


• Pigments: Black: carbon, red: hematite, white: kaolin.


• Design: Bowls only; interior: black paint on red slip (lacks wide, black banding line at rim), exterior: slipped red; opposite hatched and solid shapes; geometric lines, curves, and rectangles; interior design full, occasionally banded, or radial, sometimes with a blank circle or square at the bottom (occasionally red, but usually white).

Variants: Pinto Black-on-red: same as Pinto Polychrome, but without the white design fields.

Comparisons: Gila Polychrome has an interior banding line (broad, black) just below rim and is dominated by bold solids. Cliff Polychrome has a banding line and upper design field, and is generally in the recurved bowl form, which is rare in Pinto Polychrome.

Pinto Polychrome, AD 1280-1300, is the earliest of the three Salado Polychromes and is almost entirely in the form of bowls. Exteriors are red slipped and interiors are white slipped with designs in black organic and some red paint. Sometimes the interior slip is a pinkish salmon color. The exteriors may have black or wide white lines on the red background. The white designs are similar to those on St. Johns Polychrome and may be copies of this type. Pinto seems to be a time of experimentation wtth new combinations of colors and techniques. Pinto Polychrome seldom had a thick band or "lifeline" common in the other two Salado Polychromes. Designs usually fill the entire interior or less commonly leave an open area in the bottom. It is found in the area from east-central to southeastern Arizona concentrating on the Salt River and Roosevelt Basin areas.

Pinto Polychrome was defined by Gladwin and Gladwin (1930). This type represents the earliest Salado polychrome type and is reflected almost exclusively by bowl forms (Crown 1994; Lindsay and Jennings 1968). Pinto Polychrome has the most limited distribution of the Salado Polychrome types and occurs in a corridor from east-central to southeastern Arizona and is very rare but may occur in site in west-central New Mexico. Pinto Polychrome was produced during the late thirteenth and early fourteenth century. The interior bowl surface is covered by a poorly to well-polished red slip while interiors are covered by a polished pearly-white to pinkish slip. The red slip commonly covers the entire exterior surface but may be limited to band just below the rim. The white interior is decorated with designs in a black organic paint. Interiors are commonly decorated with opposed solid and hatched designs. These designs are organized in broad rectilinear or curvilinear motifs that include broad and fine lines and closely spaced hachure. Designs usually begin from the bowl rim and commonly fill the entire interior surface, although a small circular area near the center may be left unpainted. These designs are similar to those noted in St Johns (Tularosa style) Black-on-white. Exterior surfaces may be sometimes decorated with black paint or white clay slips. Those in white slip tend to be thick and similar to those occurring in interiors of St Johns Polychrome and indicate relationship between these types.
