St. Johns Anasazi bowl

St. Johns, Arizona, is a little bit south and west of Gallup, New Mexico, near the border that these two U.S. States share. The Anasazi potters of St Johns have been credited with being first to make polychrome pottery during this 1175-1300 prehistoric period. Prior to that occurrence, all pottery was black on white or black on red. These potters produced the standard black on red on the interiors of bowls but added white on red to the exterior, culminating in adding the third color for a polychrome designation. This was a profound change that continued for the next 200 years throughout New Mexico and Arizona.
