I’ve been testing a few more inks and added a couple new pens to my collecion
first off, I tested the standard Parker Jotter ballpoint refill, the Paper-Mate stic ballpoint, a Rotring 600 Rollerball refill, and a MontBlanc rollerball refill, immersing the inked test paper in 91% Isopropyl alcohol;
the Paper-Mate and Jotter refills faded rapidly, within the first 5 seconds of exposure, over 80% of the ink just dissolved, after 5 minutes, the ink was almost completely gone (I’d say about 98% gone), the MontBlanc and Rotring inks were unaffected, and I got the same results with Xylene
after a 5 minute water rinse, the ballpoint ink had completely vanished, and, surprisingly, the Rotring ink had faded by over 80%, it was almost gone, the MontBlanc ink was unaffected by water
as a final test, I sprayed the paper down (after letting it dry first) with SuperClean degreaser, the Rotring ink faded to 98% gone, the Montblanc ink completely dissolved, although at this point, the paper started to exhibit structural failure
Basically, most ballpoint ink is not permanent, and in fact can be washed off with common household chemicals, the only ballpoint ink I have found even remotely acceptable is Fisher’s ink, used in their pressurized “Space Pen” refills
If you use ballpoint pen to fill out checks or other sensitive legal documents, the ink can be quite easily removed from the paper, typically in under 10 minutes
I’ve also been documenting my tests over at “fountain pen network dot com”, I go by MacTech there too
Oh, and the two pens I’ve added?
a Rotring 600 Rollerball, gotta love a pen machined out of a solid piece of brass, it’s got serious heft and balances exceptionally well, both posted and unposted, I was a bit annoyed that the Rotring’s refill didn’t use “bulletproof” ink (solvent resistant and water resistant pigment-based ink that bonds with the cellulose paper fibers), so I took a refill out of one of my UniBall Signo 207’s, trimmed about 1/8" off the open empty top of the refill, and swapped out the Rotring refill, now I have a ruggedized pen that uses Bulletproof ink
and a Lamy 2000 fountain pen, my first piston-filled pen, and I absolutely love the thing, made out of “Makrolon” (Fiberglass reinforced Nylon), this thing is built to take a beating and come back begging for more, it’s the SureFire G2 flashlight of pens, the Jeep CJ series of pens, plus it has the smoothest, most responsive nib i have ever used, buttery smooth and a small amount of flex adds to the expressiveness of the written word
