Scores of open pit ovens for firing the pottery can also be discerned. It is tempting to think of this vast pottery-making industry as a sort of a 'packaging facility' for perishable commodities that were exported in exchange for luxury goods. The shreds are of kiln-baked ware that includes jars, plates, pierced colanders, lids with knobs and fine terra cotta bangle-shaped pieces. The pottery is wheel-turned and mostly pink, with a few buff samples. Some wares, particularly jars, have a reddish glazed band around the neck. The designs are a decorative feature of most pottery and are only of black colour. Designs are restricted to geometrical shapes and include horizontal lines of varying thickness, fish scale patterns, intersecting circles, comb-like patterns and wavy lines. Human and animal motifs are notably absent. 'Potters marks' are evident on the rims of some jars and pots. The complete absence of toys, seals, statues and jewelry, at least at the uppermost level, indicate a rather utilitarian environment. Further excavation is bound to reveal at least some elements that might mitigate the seeming sociocultural isolation of this Harappan outpost. Abandonment and relocation Sokhta Koh may have been abandoned due to recession of coast caused by one or more of following reasons: Gradual or catastrophic tectonic uplift Deposition of alluvial soil/silt in Shadi Kaur delta Deposition of sand on beach and in the estuary by wave action Evidence of ruins of another location nearer to the sea, at the mouth of Shadi Kaur, seems to indicate possible relocation after the estuary harbour at Sokhta Koh had dried up due to coastal recession. Discovery of a harbour, as well as the source of firewood for large-scale pottery firing would be significant challenges for future excavations. Significance as a trading outpost Chris J D Kostman in his paper, The Indus Valley Civilization: In Search of Those Elusive Centers and Peripheries , discusses: "A primary, if not the primary, rationale for long-range trade driving force would be a need for 'luxury goods,' raw materials, and other items not found in the riverine alluvial plain which made up the vast majority of the Indus Civilization. In the Indus Valley, sought-after materials included copper, gold, silver, tin, jasper and agate cherts, carnelian, azurite, lapis, fine shell, steatite, antimony, and ivory. Forays would have been made towards and beyond the civilization's peripheral areas to obtain these goods. At the minimum, then, there
