The Art of Chinese Inkstones
Inkstones, one of the Four Treasures of the Study, provide the grinding surface for preparing liquid ink from solid inksticks. The stone's quality directly affects ink preparation and, by extension, calligraphy and painting results. Four inkstone types achieved particular renown: Duan, She, Tao, and Chengni.
Duan Inkstone
Duan inkstones from Guangdong province rank first among the four famous types. The stone occurs in purple, green, and mixed colorations, with fine, even texture ideal for ink grinding. Quality Duan stone feels smooth and slightly moist to the touch, producing ink efficiently without excessive wear.
The best Duan stone shows 'fish roe' patterns—fine dots visible on the surface. 'Fire mark' patterns indicate superior material. Duan inkstones were imperial tribute items from the Tang dynasty onward, with the finest pieces reserved for court use.
She Inkstone
She inkstones from Anhui province offer harder, more resonant stone than Duan. The material features distinctive patterns including 'rooster tail' and 'water wave' effects. She stone produces sharp, crisp ink suitable for precise brushwork.
The harder surface wears more slowly than Duan, making She inkstones durable for daily use. Some calligraphers prefer She stone for its audible feedback during grinding, finding the sound conducive to meditative preparation.
Tao Inkstone
Tao inkstones from Gansu province represent a harder, greener stone type. The material was particularly valued during the Song dynasty, though production declined subsequently. Genuine Tao inkstones are rare in the contemporary market.
The stone's hardness requires more effort in grinding but produces exceptionally fine ink particles. Tao inkstones suit calligraphers who prefer deliberate, meditative ink preparation.
Chengni Inkstone
Chengni inkstones differ fundamentally from quarried stone—they are molded from processed clay and fired like ceramics. Produced in Shanxi province, these inkstones were particularly popular during the Tang and Song dynasties.
The manufacturing process allows controlled texture and porosity. Quality Chengni inkstones rival stone for grinding efficiency. The material's ceramic nature makes it more vulnerable to damage than stone alternatives.
Selecting and Caring for Inkstones
Quality indicators include fine, even texture without grit or inclusions. The grinding surface should feel smooth but not glassy—slight tooth helps break down inkstick particles. Sound when tapped indicates structural integrity.
Care involves regular cleaning after use and avoiding extreme temperatures or impacts. Traditional practice includes periodically seasoning inkstones with tea to develop patina. Never use abrasive materials that might damage the grinding surface.
