Tea Canister 1769 Joseph Smith This earthenware tea canister is one of the earliest known dated examples of American pottery. Although decorated in the Pennsylvanian German decorative technique of sgraffito, it displays the potter's attempt at emulating the fashionable English, salt-glazed, stoneware tea caddies of the 1740s and 1750s. This redware caddy, however, is much larger than its English prototype and the naive design of the tea plant bears little resemblance to that of the English salt-glazed original.. Tea Canister 8267
