Duanxi inkstone, simply called Duan stone, is produced from the Duan Creek on Fuke Mountain in Gaoyao City, Guangdong Province. It obtained its name because in the past, this site was inside Duanzhou (today’s Zhaoqing). The stone is mainly composed of Devonian sericite shale with small amounts of haematite (3–5%) and quartz (10–20%), and it has a density of approximately 2.78 g/cm 3. High-quality Duanxi inkstone is purple with cyan or white hues, and has a fine texture. It is also chemically stable, and weakly absorbs and percolates water but strongly holds water, and so it has the quality of ‘being fine but non-slippery, tough but not rough, rapid ink making and full moistening of the writing brushes’. This inkstone has various patterns and colours and sometimes has a stone ‘eye’ (stone grain) that enhances its character. It has numerous features, such as cyan flowers, white banana leaves, fish brain jelly, fire brands, sky blue, ice threads, stone eyes, jade, gold and silver threads...
