This rather obscure body sherd features a fascinating set of interlocking wedge/triangle impressions--interlocking like a set of upper and lower teeth. This could be a shoulder sherd, but it's impossible to say. The fabric is a completely different color (black) from the grayish brown interior and exterior surfaces. If this is the result of an interior and exterior slipping process, they are VERY thin slips. It may result from firing atmosphere control only. The interior surface is covered with horizontal textile impression lines which orient the exterior wedges horizontally as well. Finger impressions on the interior surface suggest that the potter used their fingers to hold the vessel wall in place as they impressed each wedge shape on the exterior. This must have been done before the vessel was leather hard. No subsequent effort was made to smooth over the interior finger marks. While the majority of inclusions are medium sand, there are numerous coarse sand inclusions mixed in. SAXS analysis conducted at ANL on 3/16/06. Radiograph analysis on 09/07. Designated MAE 169.
