During the centuries the Salado lived in the Tonto Basin, their culture expanded and diversified. Their beautifully decorated pottery and elaborate textiles show us a people well versed in handicrafts, and with a highly developed artistic sense. Sufficient discretionary time to transform functional household goods into works of art is one indication of a thriving culture.

Clay, temper, and water are the ingredients needed for making pottery. Temper is coarse material added to the clay to give it body and keep the pot from cracking when fired. Common tempers include crushed pottery sherds, sand, quartz, and crushed rock.
Once clay and temper were thoroughly mixed, sufficient water was added to achieve the desired consistency. Pottery wheels were unknown to prehistoric Southwestern peoples; instead, Salado women built up their pots with round rolls of clay that were coiled on each other, either as a series of concentric rings or a continuous spiral. With their hand on the inside of the vessel and a small even-edged tool on the outside, the potter smoothed and shaped the walls of the pot into the desired form. The vessel could then be polished with a smooth stone, covered with a thin clay wash called a slip, and painted with elaborate designs. Finally, the vessel was fired over a bed of wood coals, probably inverting the vessel, and then carefully piling more wood around it, leaving room for the air to circulate.
Oxygen, mixed with the heat, created an oxidizing atmosphere. Varying percentages of iron, naturally present in the clay, oxidized and emerged from the firing as red, orange, or yellow. White was derived from a type of kaolin clay, and black was produced from plant material that carbonized during the firing process.
Like other pueblo cultures, the Salado made plain red utility wares for everyday use. Their decorative wares consisted of three styles of beautifully painted polychromes that were reserved for ceremonial use and burial offerings. These Salado polychromes form one of the most popular pottery types ever produced in the Southwest and are often called the hallmark of the Salado tradition.
Pinto polychrome, the earliest of the styles, first appeared around AD 1200. These bowls have red slipped exteriors, and white slipped interiors that are painted with black designs. The designs involve mixed geometric and curvilinear motifs in broad line, fine line, and hatchur, which cover the entire interior of the bowl.
Gila polychrome, developed from the earlier Pinto polychrome style, also has a red-slipped exterior and black-on-white interior. These bowls are decorated with bolder, more variable designs that usually cover the entire interior, but are separated from the rim by a broad encircling band. This band, or "life line”, usually has a short gap, possibly to allow the spirit of the bowl to escape.
Tonto polychrome is distinguished from Gila polychrome only by the addition of red design elements on the white slip between the black painted elements. Tonto Polychrome is primarily confined to jars and may be simply a variety of Gila Polychrome.
