Stone vessels continued to be made, but they too were decadent. Carving in relief was largely replaced by incising. Life-forms in relief, when they do appear, are highly conventionalized. Many of the vessels are of steatite. There were some effigy vessels, representing animals and birds, which had shallow basins hollowed out of the backs. Metates and mortars and pestles were well shaped. Some hoes first appeared during Sedentary times, and it is thought that they may have been intrusive. Stone projectile points were long and slender and beautifully flaked. About half had lateral notches and the others were unnotched forms characterized by deep serrations. Stone was widely used as a material for ornaments. A great variety of disc beads were manufactured and the first ear plugs are found in sites of this period, although, as has been previously noted, they are seen on Pioneer figurines and quite possibly had been worn since the earliest times. Some particularly interesting finds include stone objects believed to have been nose-buttons or labrets. Figurines do not show the use of nose-buttons, but they do show ornaments just below the corners of the mouth and these may have been worn through the fleshy part of the chin. Ornaments worn through the nose or chin strike us as strange, for they have never won approval in our particular society, but they have been quite common in other parts of the world. In any case, a glimpse at a woman’s hat shop today offers convincing proof that anything can become fashionable and socially acceptable. Shell work, already so well developed among the Hohokam, reached its peak in Sedentary times. Mosaic work, in which both shell and turquoise were used, achieved its highest development. The technique employed must be described as overlaying, rather than as inlaying, for depressions were not cut to receive the pieces which, instead, were laid on the surface. Due to the placing of these mosaics in the cremation fires, we know little of their composition beyond the fact that shell was usually used to provide a base for the overlay. Individual pieces were cut in the forms of animals or geometric figures. Disc beads, characterized by large perforations, and pendants were widely made. For the latter, the trend was away from life-forms and toward geometric figures. Many finely carved bracelets were made. Shells with painted designs appear first in Sedentary levels, but, due to the impermanent nature of the paint, there is no assurance that this technique may not have been developed some time before.
