Lot 75. Two small Cizhou-type black glazed bowls with russet markings, Northern Song-Jin dynasty (960-1234); 3 5/8 and 2 3/8in (9.3 and 6cm) diam. Estimate US$ 3,000 - 5,000 (€ 2,700 - 4,400). © Bonhams.

The larger bowl of unusual form with straight sides that taper sharply inward to the carved foot ring and recessed base, the black glaze on the walls and well painted with matte russet stripes, the exposed fabric of buff color; the smaller bowl subtly formed with a slightly inverted lip on the deep well curving gradually inward above a well-formed foot ring, the black glaze on the exterior ending in welts and mottled with minute gray flecks and russet patches that appear as much larger 'partridge feather' markings on the black glaze across the interior well, the exposed fabric of pale gray-white hue.
