American Folk Art / Utilitarian Stoneware
Medium & Technique
Salt-glazed stoneware with cobalt slip blue decoration. Technique involves throwing on a potter's wheel, applying hand-painted or slip-trailed cobalt oxide ornamentation, and firing at high temperatures while vaporizing common salt in the kiln to create the distinctive 'orange peel' pitted glaze.
Creation Period
mid-to-late 19th Century (circa 1860–1890)
Dimensions & Format
Estimated 10-12 inches (25-30 cm) in height; cylindrical vessel format with flared rim.
Subject Description
A utilitarian storage vessel featuring stylized blue floral and scrolling leaf motifs. The decoration is applied in cobalt oxide, which turns deep blue during the high-heat oxidation process. The form features an ovoid-to-cylindrical body with integrated lug handles.

Art Historical Significance
Represents the quintessential American utilitarian ceramic tradition. These vessels were vital for food preservation in the 19th century and are now highly collectible as examples of early American industrial folk art and craft history.
Notable Features
Features hand-painted cobalt scrolling motifs which are more desirable than plain crocks; integrated lug handles; 'orange peel' texture characteristic of traditional salt-firing methods.
Condition Issues
Notable horizontal and diagonal cracks (stable but visible) across the floral decoration; a significant surface flake/chip (pitting) above the floral motif exposing the clay body; typical salt-glaze 'blow-outs' and kiln iron spots; wear to the rim and base.
Conservation Recommendations
Maintain in a stable temperature environment; avoid lifting by the handles due to the visible structural cracks; clean only with a soft, dry brush or slightly damp cloth; do not use abrasive chemicals as they may penetrate the crazing/cracks.
