Kwz Brown Pink Colour Shift

[by_a_Lady]

I ordered a sample of KWZ Brown Pink a while ago (cannot remember when exactly, it must have been a couple of months) and enjoyed it greatly in a PenBBS 456 for a time, until recently I noticed that the colour had shifted toward a decidedly non-pink brown, almost like J. Herbin Lie de Thé.

Has anyone experienced something similar with this ink? I like the "normal" colour a lot and am thinking about buying it, but if this is regular behaviour then it is out of the question. Since it's not IG, the only other two possibilites I can think of is that either it was a faulty bad, or the bottle from which the sample was taken was subjected to some conditions that caused the colour to go off.

I would get in touch with Konrad and pose the question to him. If it is a fault, I am sure he would want to know about it.

Did the color change in the sample vial or inside the pen? I wonder if there was some contamination somehow; since it's a pretty small amount of ink to begin with, not much of extra agent would be needed to make a visible change.

It changed inside the pen, which is a vacuum filler and prone to trap ink in its many nooks and crannies. I don't remember which ink I had filled it with just before KWZ Brown Pink, but it makes sense.

I did heed your advice, and he confirmed that it was an unusual thing that's unlikely to happen with a full-sized bottle. He thinks that it might have been because of the vacuum filling system, which I agree with.

 

So I'm going to go ahead and order a bottle - and a couple more colours as well! I really liked Grey Plum and Green Gold, mayyybe Grapefruit?

Good to hear you were able to figure it out! Brown Pink is one of my favorite standard colors from KWZ, my bottle is from October 2016 and hasn't degraded a bit.

 

When I find myself wanting more than one KWZ ink, I usually end up getting all of them, they're too tempting for my own good!

Is it one of KWZ's iron gall inks (marked with "IG")? If yes, that can explain a color shift. Iron gall inks darkens when they are exposed to air. It can happen in bottle, in pen or (first of all) on the paper. It is the iron content which oxydizes to iron oxydes (the same as rust) which is embedded in the paper and is light and water resistant. Freshly made iron gall ink are almost colorless, so Iron gall inks have more often than not also an aniline dye added to ease visibility when writing. This dye can wash off with water and can fade in light. If that happens the iron component will be left in the paper as grey or black writing. With time (months-years) it will change into a rusty brown color.

No, I think Brown Pink is a standard line color. But it's a good question, because KWZI are known for their exceptional IG colors

I sort of have the same problem as JakobS -- and it's even worse for me because there was one I wanted to try early on (that being IG Cherry); it didn't work out for me to get, and it's no longer on their list.
