This is an Inkstone whetstone specifically designed for high-end calligraphy inkstones. Please use it with the whetstone surface parallel to the inkstone surface.
Traditional Inkstone Whetstone — 硯用泥砥石 — is a natural mud slate stone made specifically for maintaining high-end calligraphy inkstones, sold here as a set of four.
Over time, glue from the ink and paper fibres from brushes can cling to and harden on an inkstone's surface, clogging its microscopic texture and dulling the clean colour it should draw out.

Thickness: 20 mm
Weight: 30gram ( 1 piece ) .
Material: Natural mud slate
When paper fibers adhering to ink or brushes stick to and solidify on the inkstone's surface due to the glue in the ink, clogging occurs. This makes it difficult for the ink to produce a clean color.
Soak the inkstone for about an hour and the whetstone for about five minutes beforehand to reduce scratching.
Brown particles will come off the whetstone, but do not rinse them away. Instead, gently rub the whetstone parallel to the surface of the inkstone.
By filling the inkstone with water and carefully polishing it with this whetstone, you can remove deposits from the microscopic protrusions on the inkstone surface, maintaining it in optimal condition.
As the particles of the whetstone break down into finer grains during polishing, they polish the surface of the inkstone. This allows a single stone to function as multiple grades of artificial whetstone.
