The following are relatively early (possibly 1850’s for the ovoid jar) examples of wax-sealers from my research collection. The first two are hand-thrown on a wheel while the last example is made from an extruded tube of clay with hand-formed, or at least hand-joined, top and bottom. Note the width of the openings of these relative to the vessel diameter and the deep incised groove where the metal top would set. Also, a consistent detail is that the inner edge of the opening is raised or everted as opposed to the oyster jars where the inner edge is flush or sloping inward to receive the cork.
