Exceptional One-Gallon Stoneware Jar with Cobalt Floral Decoration, Stamped "J. SWANN / ALEXA," Alexandria, VA origin, circa 1820, ovoid jar with tooled shoulder, semi-squared rim, and downward-angled tab handles, brush-decorated on the front and reverse with a daisy plant. Cobalt highlights to handle terminals. Relatively few examples of cobalt-decorated stoneware by Swann are known. The design on this jar closely relates to motifs used by Baltimore, Maryland and Richmond, Virginia potter, Thomas Amoss. Coupled with the jar's fine decoration is a desirable size and unusual potting to the vessel in its rim and handle construction and wide-bodied form. Provenance: From a recently-surfaced Virginia collection. Very nice condition. Chips to reverse end of one handle. A chip to front end of one handle as well as two lesser glazed-over chips to same handle. A minor in-the-firing ping to rim. A small, partially glazed-over base chip and other very minor in-the-firing chipping to base. Some very faint lines to underside, continuing onto base area of jar, possibly in-the-making and only partially visible on interior. H 9".
