Something I’ve been meaning to post about for a while is a strange phenomenon that occurs when sheen-prone ink is at the last but of a pen’s fill (i.e., still able to write but going to need a refill very soon).
Sheeny inks’, well, sheen appears to concentrate itself on the page when the pen is running low. I’m guessing this has to do with evaporation, as diluting sheeny ink will do the opposite.
It’s a really fun thing to have happen, if somewhat unpredictable.
Here’s a sample of Sailor Sky High in a Waterman 52½V that was running low. You can see the intense sheen on the “Wa”, and the lessened amount on the “ter…”, which is when I stopped and refilled.
Just one more thing that makes fountain pens awesome. :)
