It is unusual to find a bowl of this type with a Qianlong mark, but one in the collection of the Asian Art Museum, San Francisco, is illustrated by He Li, Chinese Ceramics, A New Comprehensive Survey, New York, 1996, p.284, no.565.For a Kangxi precursor of this Qianlong example see the bowl in the Percival David Foundation, illustrated by W.Ming in Rare Marks on Chinese Ceramics, London, 1998, pp.32-33, no.6. The eight-character mark on the base may be translated, 'made for the Zhonghe Pavilion in the renzi year of Kangxi', corresponding to 1672. Yongzheng-marked examples are represented by one illustrated in Old Oriental Ceramics Donated by Mr. Yokogawa, Tokyo National Museum, 1953, pl.389; and another included in the exhibition, Chinese Antiquities from the Brian S. McElney Collection, Hong Kong Museum of Art, 1987, no.100.Compare two bowls of this type sold at Sotheby's Hong Kong: the first on 21 September 2021, lot 137 and the second on 30th November 2018, lot 745. 侈口翻唇，斜躺腹，外壁出兩匝弦紋，圈足直壁，通施紫金釉，足底白釉上書青花「大清乾隆年製」篆書款。 乾隆八年《浮梁縣志》所記唐英撰《陶成紀事碑記》載有唐英督陶所造所創五十七種釉色中有「仿紫金釉，有紅黃二種」，見張發穎編，《唐英督陶文檔》，北京，2012年，頁5。此乾隆款紫金釉弦紋盤可比較三藩市亞洲藝術博物館藏一件乾隆紫金釉弦紋盤，見Li He著，《Chinese Ceramics: A New Comprehensive Survey from the Asian Art Museum of San Francisco》，紐約，1996年，頁284，編號565。此類紫金釉碟康熙雍正時便已燒造，或為本件據本，參考英國大維德基金會藏一件康熙紫金釉弦紋盤，惟圈足較高，見劉明倩著，《英國大維德美術館暨維多利亞博物院藏堂名款瓷器》，倫敦，1998年，頁32及33，編號6。東京國立博物館藏一對雍正款紫金釉弦紋碟亦可參考，見《東京國立博物館圖版目錄中國陶瓷篇II》，東京，1990年，頁180，編號708。還可比較另外兩例相似之乾隆紫金釉弦紋盤，分別於2021年9月21日及2018年11月30日售於香港蘇富比，拍品編號137及745。
