Possibly Unique Four-Gallon Stoneware Jar with Brushed Floral Decoration, Inscribed "Sample," Stamped Under Handle "B.C. MILBURN / ALEXA," Alexandria, VA origin, circa 1850, squat-shaped ovoid jar with tooled shoulder, squared rim, and applied tab handles, decorated with brushed slip flowering vine across the front, featuring seven flowers of two varieties. Reverse slip-trailed with the large word "Sample," presumably indicating that this jar was a sample or test piece for the pottery. The color of the decoration and inscription on the jar suggests that the piece's decorator was testing a batch of slip, which was either manganese-based or insufficient in cobalt. This interesting jar is possibly the only example of Alexandria stoneware known with a slip-decorated word, and is revelatory of the processes potters underwent in making salable ware. Provenance: Recently discovered at a yard sale in the Washington, D.C. area. Inverted Y-shaped crack extending from rim on reverse. 2" triangular rim chip on reverse, and a smaller rim chip on interior of rim. Two tight cracks in underside. Small chip to end of one handle. H 13".
