清乾隆 白玉穿雲游龍螭耳方斗

the tapering sides rising from a short spreading foot, with articulated handles in the form of 'climbing' chilong, each with ruyi clasped in their jaws, the front and reverse panels carved in low relief with a lively four claw dragon writhing above waves among trailing cloud scrolls, the stone of an even white tone

It is likely that this bowl would have originally had feet to the corners of the base, which have been removed and re-carved. There is a 2.5cm crack running through the base from the sides of where one of these feet would have been. There are also some flaws in the stone.

此盌以圓潤白玉雕琢，比例均稱完美，琢磨細緻，盌面潤澤，光可鑑人。乾隆一朝，御作坊多以小塊玉石製器，皇帝更常賦詩題詞，感嘆玉石稀罕。自西征準噶爾，平定于闐、葉爾羌（今新疆），其地所產碩大良玉，至此歲歲朝貢，源源不絕。
