(2). 十八/十九世紀 黃花梨嵌松花石硯屏 Provenance: Nagel, 17 May 2008, lot 567 來源： 納高拍賣行，2008年5月17日，編號567 Compare with a small Songhua stone table screen illustrated in Sidney L. Moss Ltd., Escape from the Dusty World - Chinese Paintings and Literati Works of Art, London, 1999, no.83. Paul Moss notes that there are two varieties of Songhua stone, the purple and green variety from Liaoning province, and the purer green Songhua from Jilin province. The Qing expansion to the north gave access to the quarries of both Songhua stone varieties. Objects made of Songhua stone were rare and were reserved virtually exclusively for imperial use. They comprise inkstones but also a small number of table screens such as the present example, see Jane Chi Jo-hsin, A Special Exhibition of Songhua Inkstones, Taipei, 1993, who illustrates 89 inkstones and two desk screens in both types of Songhua stone from the Imperial collections.
