Reference work entry
Dunhuang stone mainly refers to the desert wind-ground stone and riverbed patterned stones. It is named after Dunhuang, and in the past it was given to the emperor as a tribute from local officials, as described in the early records of the Song Dynasty: ‘Li (polished) stone, a tribute from Suzhou’. The wind-ground stone is rough and angular as a result of erosion by the desert wind. It is mostly quartz with a Mohs hardness of more than 7. It is generally light grey with a glassy lustre and can be categorised into Datan agate, Gobi jasper, silicified wood, desert lacquer and bone stone. High-quality Dunhuang stone has a good colour and shape resembling both simplicity and marvel (Fig. 31).
