Tsukushi, or horsetail, is a wild plant found in Japan. It’s green in the spring but turns brown later in the season as the plant dries out. It is edible and is often used it soups or fried.
Tsukushi is a pure brown that darkens significantly when it dries in concentration. It has low shading and some sheen. The ink tends to sheen in a purple tone that can also be seen when applied very lightly on some papers (often with a swap). The sheen and shading with the purple aren’t as visible when writing as when the ink is being tested or demonstrated.
The purple tones in the ink are readily apparent in the ink chromatography, as are some black/grey tones which dark the ink. The ink has some water resistance but will lost its color when the it get wet. The black tones in the ink are most resistance than the purple and reds that combine to give it its distinctive brown coloring.
This ink is a popular choice to pair with Pilot’s brown Custom 823 fountain pen.
