Figure 54 Porringers, William Rogers, Yorktown, Virginia, 1720–1745. Lead-glazed earthenware. Diam. 7". (Courtesy, National Park Service, Colonial National Historical Park, Yorktown Collection.) COLO Y 71190, COLO Y 71182. These bowl-like vessels have a flat base, curved out-sloping walls, flattened and usually down-sloping (toward the interior) rims, and a C-shaped, circular-sectioned handle attached to the rim. As with most of Rogers’s earthenwares, the porringer has a reduced gray-green to red-orange color related to the kiln temperature and the atmosphere in the kiln.
