Multicolored Ink

[crunchmaster]

 

Ok, I admit, I GIMPed it. But what a neat idea, eh? See, I used to have a colored pencil that was multicolored: as you wrote with it it would cycle through a rainbow of colors. I realize it's probably impossible to do this with a fountain pen ink without violating the laws of physics...but I wonder...I mean, Nathan had an ink that changed color when exposed to RF energy, and we never would have guessed that would work. Any ideas?

I've seen caliken do something similar but more subtle with a dip pen, but I think it would be a real challenge with an FP.

Well, thanks, but I do know about iron-gall ink--I have a bottle of Lamy blue-black, even. That's not what I mean at all. I'm trying to imagine some kind of ink solution in which the color components don't mix together very well, yet they still flow...sequentially? I know, probably against the laws of the universe.

You could achieve something like this by mixing a red ink (e.g. Pelikan Red) with an erasable blue ink (e.g. Pelikan Royal Blue). After writing and after it has dried, scribble over it at random with a Pelikan Super-Pirat ink eradicator. It will erase the blue wherever and leave the red. The result will be similar to what you've shown.

I suspect it may be possible to do this with a suspension of immiscible inks, possibly bound by a detergent. However, it would not come out evenly divided like this.

They carry this ink at a store in town, it's on the same shelf as the cans of striped paint.

Well, there's the Pilot Parallel pens with their ink. It only works for short periods of time.

Certain big name black inks have been observed to give a distinct red stripe at times, others provide a surprising grey dual colour as well.

How about two shades of ink; one bound TO the detergent and non-polar in nature, while the other shade is polar, and in the solvent? Upon writing the solvent based ink comes out naturally while the Micelle trapped ink ruptures when written with due to the pressure. The polar/non polar interactions could keep the colours separate until dried on the paper...

 

Might not event need to be bound to the detergent, Just need Micelle formation... Bring it just above the CMC? =o

 

Cleaning it out from the pen though would be an absolute pain...

Yes, this is the right kind of idea. It is at this point that I wish I had paid attention to chemistry class instead of Jennifer. I hope an ink chemist will read this and derive an idea that they can run with from it.

Now that's what I'm talking about! Oh, Naaathaaan...

You can cross-dip from inkwell to inkwell with a dip pen.

Wow, jbb, that's great! What inks did you use? And does cross-dipping (sounds like a bad habit, haha) spread the ink on the nib into the ink container? Seems like it'd cross-contaminate.

The inks in my inkwells are mixes of random inks that have been added over a long period of time so I really don't know what's in my red, blue or green inkwells anymore. In the picture I was also dipping into some homemade metallic inks. My dip pen inks are entirely contaminated! I suppose eventually they'll all be brown ink.

That is lovely!!!

Great now i want a dip pen. i do wish a FP could do variegated colors.

The micelle idea is a good one, BUT.

 

1. You would have to make sure the micelles were large enough.

2. The Micelles evened out at the same density as the surrounding solution.

3. The micelles somehow repel each other and do not agglomoerate (is that the correct word for micelles?, anyway glob together). A good example of this is the casein micelles in milk. Unfortunately I think these micelles are too small to get the effect you are looking for.

 

the biggest issue of course is that having hydrophobic liquids (oils) and water coming out of the same pen is going to cause problems. One experiment could be to add a water soluble and fat soluble dye to milk and see what happened.

I have one listed in the FPN classifieds.
