Grueby Pottery sphere vase with a deep heavily curdled and separated oatmeal white matte glaze showing the clay body. It measures 4 1/8 inches in diameter at the widest point and 3 1/2 inches tall. It is in great condition with no chips, cracks, firing flaws, or repairs. Illegibly marked with the Grueby Pottery Boston USA die-stamp. A great form with an unusual glaze effect from the quintessential Arts & Crafts New England art pottery.
