A ROBIN'S EGG GLAZED WATER POT, QING DYNASTY China, 1644-1912. Of domed square form with canted corners and lipped ring, applied to one side with a clambering chilong, the thick and unctuous glaze of evenly streaky lavender and turquoise tones covering the exterior, base, and interior. Provenance: Formerly from the Vermeer & Griggs Collection, old collection label to base. In 1976, Michael L. Vermeer (1947-2015) joined Alan Griggs (1939-1995) to form Vermeer & Griggs, based in Los Angeles, California. Alan's extensive knowledge of Chinese ceramics from the Shang to Yuan dynasties was complemented by Michael's strong interest in Ming and Qing Imperial wares. In 1989, the firm started to deal exclusively in Asian art, specializing in their favored field of Chinese ceramics. Condition: Good condition with minor wear and firing irregularities, the foot with small nicks and associated microscopic touchups, the interior with extensive soiling. Weight: 105.7 g Dimensions: Width 6 cm, Height 5 cm Expert's note: The present washer is complemented by the extraordinary effect of the robin's-egg glaze, which is achieved with the use of copper and arsenic as an opacifier to create an opaque stippled turquoise glaze. There are two distinctive types of robin's-egg glazes: the first stippled with turquoise and dark blue, as in the present example, and the second streaked with copper-red. 清代爐鈞釉筆洗 中國，1644-1912年。圓頂方底，斜角圓唇。一側有一條攀爬的螭龍，通體施厚而光滑的薰衣草和綠松石色釉。 來源：來自 Vermeer & Griggs 收藏，底部可見收藏舊標簽。1976, Michael L.
