Thickness is the most standard aspect and in about 90 percent of the sherds runs between 4 and 7 mm. The upper limit reaches 11 mm. in occasional examples. The two varieties of tangas have a time distinction as well as a dif- ference in shape. The red-slipped type (pi. 82, d-e) is in the minority in the earlier sites, but becomes equal in popularity at Camutins and dominant at Guajara. This transition is probably related to the trend toward abandonment of the more complex and precise types of ceramic decoration that is characteristic of the ceramic history in general. Although the red-slipped tangas are often slipped on both sm"faces, the painted ones are generally slipped only on the exterior or convex sm-face, with the slip carried over onto the interior in a band along the edge 4 to 9 mm. wide. The design is composed of fine, single, red.
