Important and Possibly Unique Six-Gallon Tin-Glazed Redware Jar with Profuse Brushed Cobalt Floral and Sponged Decoration, Stamped "I. BELL," John Bell, Chambersburg or Waynesboro, PA, circa 1830, large-sized, ovoid jar with rounded rim, incised way line decoration around shoulder, and ribbed pocket handles with depressed terminals. Surface coated in a highly unusual tin slip and exuberantly-decorated completely around the jar's cirmcumference with brushed cobalt slip tulips and sponged banding. Additional cobalt sponging on top of handles. Exterior surface covered in a clear lead glaze overlying the tin and cobalt slip. Interior surface covered in a reddish-brown lead-and-manganese glaze. Impressed with recessed "I. BELL" maker's mark at shoulder. While this jar is described in Comstock's The Pottery of the Shenandoah Valley Region as a Hagerstown product made circa 1823, the mark on the jar appears to be a recessed Bell mark used circa 1830-1850, and not his raised-faced mark of an earlier period. However, the early-style glaze treatment and handle construction indicate this vessel was probably made shortly into the introduction of the recessed "I. BELL" mark, circa 1830. This phenomenal jar ranks among the most profusely-decorated examples of pottery known by a member of the Bell family. Adding greatly to its significance is the use of an opaque white tin glaze over the surface, which modeled itself after fine delftware from England and Holland. Relatively few examples of 19th century American tin-glazed pottery are known, among them a small number of Bell family products. These include a highly important inkstand, produced by John Bell in 1825 while still active at his father's shop in Winchester, VA, (believed to be the earliest documented example of American tin glaze), as well as a cake mold with cobalt floral and sponged decoration, bearing the Winchester, VA mark of John's brother, Samuel. This jar is possibly the largest and most ornately-decorated example of American tin-glazed pottery known. This jar presents Bell as a complete potter and highly-skilled artisan, proficient at throwing, glazing, decorating, and firing. In the case of this jar, Bell states that the pot's artistic merit may even be more important than its functionality. Among the thousands of signed John Bell pottery jars known, it is arguably his masterpiece of the form. Certainly the most important example of John Bell redware to come to auction in many years.
