This piece of glass is a triangular piece from what seems to be the lip of a vessel. The piece is thin and tinted a blue green with an iridescent film on many sections of the piece. this iridescence is present on all surfaces of the piece. This glass was found among washed sherds from Locus 03, which is outside the wall of the room in the operation. Based on the piece I would assume that the entire vessel wasn't very big and was very thin and fine.
