The form of the neck of this large jar sherd may be inverted cone rather than biconical. The rim might be rectangular rather than 2-part. Double check after Hasmik draws it. The sherd appears to be burned and some areas of both surfaces have small gauges. There is a gray-colored incrustation on the exterior and the interior. The hole on the neck is about 6.20mm in diameter. Both interior and exterior surfaces have multiple colors, in addition to the black that seems to be the result of burning. Hard to determine Munsell colors given the burning and mottled dark grays and browns. Have left them out. In addition to the coarse sand, the temper includes crushed rocks. Diameter may be wrong because I had to use a slightly incorrect rim chart for a rim of this size.
