Yu-Yake - Pilot Iroshizuku

[LyaT]

Reviving a very old post just to ask one question:

 

Is it normal that my Yu-Yaki darkens over time in the pen? I cleaned my pens thoroughly before inking, and I noticed it for the past few fills. The ink gets darker after 2-3 weeks in the pen. It does not become darker in the bottle.

Many of my inks in filled pens darken after a few weeks. I don't think it is any difference between the inks used to fill the pens, merely the exposure to air & loss of water from evaporation. Some I am happy to see the change & most resolve themselves after a quick dip into an old inkwell I keep filled with mere water for the times I need a quick start for a pen I have neglected.

That explains it, thank you. Yu-Yaki evaporates quickly in my Lamy Al-Star. In two weeks it almost dried up, making the remaining ink very dark. I have other Ironshizuku inks in my Pelikans, they dont evaporate this quickly. Maybe it is a ink converter issue.

Yes, Yu-yake darken over time because of evaporation. I doesn't seem to matter whether it is in a refilled cartridge or converter. Sometimes, if I have a half-converter/cartridge full of an ink that seems to have darkened, I will add a drop of distilled water to reconstitute the ink. But some inks I really enjoy when just a bit of water has evaporated. They seem to flow easier as their lubrication is more concentrated.

I find the same. Been using Yu-yake to underline (my way of Highlighting) for a couple years now. I tried several orange inks but this one has worked out the best for me.

Thank you for your information. It is reason why I always feel like the color I got is different every time (I rarely use Yu-yake for daily writing, just use it occasionally for some quick sketch). I just surprise to find out that the ink color changes overtime.

Thank for your tip to reconstitute the ink too. I will try it right away with my current Yu-yake inked pen.
