Trivia for #papernerds and #fountainpen ink lovers: I’m finding iron gall ink to have FAR slower darkening times on Yamamoto Takasago Premium bank paper, and on the “Sheep Clouds” paper. The ink color darkens much faster on Light Force and other papers. Testing continues but this difference is kinda cool and weird, to me. Anybody know why this happens? The brown ink pic is the bank paper, orangey pic is the Sheep Clouds.
