This rim fragment of a 'marsh bowl' is made of a dark blue turquoise faience. Faience is a glazed non-clay ceramic material made from quartz sand and natron. The decoration on the piece evokes the fecundity of the Egyptian marshes with a water lily and fish motif on the interior and the end of a lotus petal on the exterior. "Uncountable' numbers of such faience bowl fragments, including this one, were exavated at the site of Deir el-Bahari.  They are from shallow open bowls popular in the early 18th Dynasty.  These bowls are associated with the worship of Hathor and other goddesses and they probably served as votive offerings.
