真正の古典インク。揺るがず、保存に堪え、数時間で恒久の線へと酸化する。五百年の化学が、いま手に入る。
The maker, the year, the line — and the language of the name itself.
The primary read, the pool at the trough, the sheen at the angle, and how much the colour shifts as it dries.
The liquid itself: pH, lightfastness, how it behaves in the bottle and inside a demonstrator.
Wetness, saturation, sheen, shading — and how feathering and ghosting test on standard cream.
Seconds to a smudge-free pass on the standard cream paper.
Where this ink belongs in the cabinet — by nib, by paper, by occasion.
