A fine teadust-glazed octagonal vase, hu, Seal mark and period of Qianlong | 清乾隆　茶葉末釉八方貫耳壺　《大清乾隆年製》款

A Japanese private collection.

Exclusively reserved for imperial consumption, teadust glaze was introduced in the Yongzheng era to emulate archaic bronzes and was popularised during the Qianlong reign.

Aptly termed 'teadust' because of its characteristic flecked olive-green tone that resembles the colour of ground tea leaves, the glaze was achieved through the use of iron oxide and careful manipulation of the firing temperature. During the high-temperature firing process, yellow crystals in the glaze precipitated, creating a contrast against the dark green ground and resulting in the desired tea-dust effect.

The robust form of the current vase accentuates its reference to the past while allowing the subtle depth of its color to radiate from the vessel. Compare two closely related vases sold in these rooms, 2nd May 2000, lot 620, and 9th October 2012, lot 3039. A vase of this type, but covered in a Guan-type glaze, was sold twice in these rooms, 10th April 2006, lot 1606, and again, 8th October 2009, lot 1626.

茶叶末釉乃清宮御用釉色，創燒於雍正朝，取法古銅器韻致，至乾隆時期臻於鼎盛。其釉色因密佈橄欖綠色斑駁點晶，恰似細碾茶末而得名。此項工藝需以氧化鐵為呈色劑，精準控溫，經高溫窰火淬煉，使釉中黃晶析出，與青綠底釉相映成趣，終得茶末顏色精髓。

本品器形渾樸，既承古意，又使釉色層次盡顯。可資比對兩例相近作例，均售於本行：2000年5月2日，編號620；2012年10月9日，編號3039。另見同類器型施仿官釉者，曾兩度現身本行：2006年4月10日，編號1606；2009年10月8日，編號1626。
