Fugitive Ink?

[Octo]

What's the most fugitive ink? Usually I prefer eternal or bulletproof inks, but sometimes the opposite is needed. Thanks in advance.

This probably not what you mean, but Noodler's BLUE GHOST is invisible ink that's only visible under black light.

Pretty neat even though it's obviously a gimmick and one-trick-pony.

Do you want light or water fugitive ink, or both?

Fugitive: as in a artist painters color being fugitive means it will degrade over time. Just about any red will do that. And if I am correct in my recall, Parker Quink will practically disappear over time. You didn't mention any particular color. And I'm curious as to why you would want such an ink.

Amberlea's fade tests should come up with dozens.

My brain immediately went to the natural dye red from safflower which was used to dye the original "red tape" tied around legal documents. But that's not ink.

Hi,

 

From various discussions about creating enduring records, the choice of ink is only one factor, with paper and storage conditions also in the mix. We have numerous examples demonstrating the longevity of even the Washable inks (which are designed to be unstable) on ye olde paper stored in the dark.

 

As mentioned by Member Davros, one can 'erase' ink by storage conditions, typically UV exposure, or treatment of the ink+paper by rinsing with water (water spray and blotting might work.)

 

Failing that, perhaps one can modify the ink to be very unstable by conjuring a recipe consisting of a Washable ink with a [low] concentration of ammonia. The intention being that the dye would be degraded by the ammonia, and become even more unstable and vulnerable to degradation by environmental factors. The trick would be to have a predictable rate of degradation, and not damage the paper too much. That idea may be a wild goose chase.

 

Personally, when I want what I've written to degrade, I use Pelikan 4001 Royal Blue, diluted to a quite pale Value, from a pen with a narrow nib. Fingers crossed that the paper used is not archival (contains acid & lignin), and that the ink is too pale to be properly rendered by scanners or copiers.

 

Bye,

KTC - it is PROOF - water proof, fade proof and dirt proof.

BSB might hit a sweet spot between being water resistant (short term permanence) and fugitive (high UV sensitivity).
