Fine comb incised abstract swirling patterns are faintly visible in the interior. 6 5/8” diameter x 2 1/2" high. Circa 13th century. Good overall condition. There are two long old hairlines down one side of the interior and a single hairline with a fork on the other side (see closeup images). The unglazed rim edge has a few tiny frits and imperfections.
