More water tests

Recommended Posts

Since my last post on permanent ink tests seems to generate a lot of side discussion, I thought I’d toss in some more material for discussion.

 

I did this test two years ago on Rhodia paper. It, too, was a 12 hour soak in water. This one includes a wider variety of inks for comparison.

 

I included some inks I like for their color and writing properties, but they aren’t water resistant. Most of my inks have some degree of water resistance.

 

I included a photo of the sheet as it was submerged in the water bath. This is what really appeals to me. I need ink that doesn’t run off the paper when I spill water on it. Many of the water resistant inks have components that flee with the first touch of water. Some of the best behaved inks from a maintenance and flow perspective, have no resistance at all.

 

The scans show the original on the left and the result of 12 hours soaking on the right.

Me too, when talking about waterproof inks. Any (observable or detectable) impact upon re-wetting, after the ink has dried on the page, would mean the ink is (or marks made with such are) not waterproof.

Platinum Carbon Black ink is first among the waterproof inks to fit that description, I reckon, followed closely by Sailor Seiboku and Souboku (but not Kiwaguro), and Sailor STORiA pigment inks.

 

Nevertheless, an ink (or combination of the ink and a particular type of paper or medium) can be highly water-resistant if the bond between some visible component of the ink and the medium will not easily by dissolved or broken by prolonged exposure to moisture or soaking alone, even if some other impact (e.g. dye components running off the ink marks and then staining the surrounding area) makes the marks effectively illegible.

 

 

I endeavour to be frank and truthful in what I write, show or otherwise present, when I relate my first-hand experiences that are not independently verifiable; and link to third-party content where I can, when I make a claim or refute a statement of fact in a thread. If there is something you can verify for yourself, I entreat you to do so, and judge for yourself what is right, correct, and valid. I may be wrong, and my position or say-so is no more authoritative and carries no more weight than anyone else's here.

      I have the Sailor Naginata and some fancy blade nibs coming after 2022 by a number of new workshop from China.  With all my respect, IMHO, they are all (bleep) in doing chinese characters.  Go use a bush, or at least a bush pen.

      It is the reason why I'm so keen on the idea of a personal library — of pens, nibs, inks, paper products, etc. — and spent so much money, as well as time and effort, to “build” it for myself (because I can't simply remember everything, especially as I'm getting older fast) and my wife, so that we can “know”; and, instead of just disposing of what displeased us, or even just not good enough to be “given the time of day” against competition from >500 other pens and >500 other inks for our at

      Agreed.  And I think it’s good to be aware of this early on and think about at the point of buying rather than rationalizing a purchase..

      Alas, one cannot know “good” without some idea of “bad” against which to contrast; and, as one of my former bosses (back when I was in my twenties) used to say, “on the scale of good to bad…”, it's a spectrum, not a dichotomy. Whereas subjectively acceptable (or tolerable) and unacceptable may well be a dichotomy to someone, and finding whether the threshold or cusp between them lies takes experiencing many degrees of less-than-ideal, especially if the decision is somehow influenced by factors o

      I got my first real fountain pen on my 60th birthday and many hundreds of pens later I’ve often thought of what I should’ve known in the beginning. I have many pens, the majority of which have some objectionable feature. If they are too delicate, or can’t be posted, or they are too precious to face losing , still they are users, but only in very limited environments..  I have a big disliking for pens that have the cap jump into the air and fly off. I object to Pens that dry out, or leave blobs o
