A Few Faded Flowers...

Recommended Posts

Just 4 days after starting testing this in a northern orientation window. A few comments by looking in person at the test sheets, in order of resistance to fading:

 

1. Platinum Pigment Blue seems unaffected, no visible differences in the samples

2. Iroshizuku Asa Gao is a close second, there's just a very slight discoloration

3. Pilot Blue Black has slight discoloration and yellowing

4. This place is shared by Platinum Blue Black, Parker Blue Black and Diamine Grape. Discoloration is easily noticed.

5. Shared by Iroshizuku Murasaki Shikibu and Diamine Syrah (as a % of color loss).

6. Diamine Amazing Amethist is nearly gone.

 

The ball points are holding well except Parker Black.

 

Other comments: Since Platinum Blue Black has the problems associated with iron gall inks, yet it performs on par with Parker Quink and worse than Pilot Blue Black, I don't see any particular reason in insisting to use this ink against other "blue-black" alternatives.

Thanks for the test! I was supposed to send a writing sample written with Platinum Blue-Black to amberleadavis but have not gotten round to it yet.

Referring to Platinum's information about ink page and comparing to your results, it looks like what was described:

 

Many decades ago, we could not develop pigment ink for fountain pens. So we mixed ferrous tannic acid and blue dye-based ink to make ferric tannic acid, so to say “Blue Black” colored ink. I will skip boring details, but we compounded blue dyes together with ferrous tannic acid, and this Blue Black ink is became oxidized in the air after writing and become ferric. Hence, its color turns blue after writing. However, the blue dye color will gradually fades away and only the ferrous iron remains on the paper permanently.

At first, the blue color, later changed to black; that is why we call it ‘’Blue Black’’, the name comes from its function, not the color itself.

 

What I am curious to know is how it would fare against Pilot Blue Black in the long run: I read that someone here did a pH test and figured out that Pilot Blue Black is not iron gall, yet it appears to be waterproof and fade resistant, and yet It does not seem to be a pigment ink either. In your test thus far, the results don't seem all that different to me, so if indeed Pilot Blue Black is not a pigment ink, then it wins (other than possibly in the colour). Mind leaving your test on longer?

I surely will, my intention is to check every week until most of the inks are gone. Will post pics any time I see something interesting.

Thank you!!!! I love these.

Fountain pens are my preferred COLOR DELIVERY SYSTEM (in part because crayons melt in Las Vegas).

Is there any particular reason why you chose a north facing window? No criticism, just curious (when we bought our current house the so-called "master bedroom" got turned into my sewing and project room because it was on the northwest corner of the house, and therefore had both "even" light and afternoon light; also of course, because it was bigger :rolleyes: and because we thought we'd hear less street noise at night in the back corner on the same side of the house -- not realizing of course that we'd hear *more* noise because it's a corner lot and our street T's onto a fairly main road... :headsmack:).

My south windows are street facing, and I wanted to avoid displaying colored paper there, also they have grilles that would had interfered with my samples :P OTOH since most of these tests are done in direct sun, I was somehow curios what would happen when picking shadow.... so basically these samples were sitting at room temperature (no overheating by direct sun) and diffuse light. From what I've seen, it didn't help them much....

Shock - no. Surprise - yes, I didn't expect Asa Gao to perform that well. :P

I was surprised between the difference between Grape and Amethyst.

I believe they're not the same dye i.e. Amethyst is not some diluted Grape. I also noticed something strange when flushing the pen with Amethist, it came out as some sort of metallic gray, like it reacted with the fluorinated tap water and changed color. Grape made my whole sink purple as expected lol.

Grape was my most serious stainer until the KWZI 12, but both are clean now.

Yep, I have several very stable Uniball red ink pens, one is specifically marked "uni-ball Vision fine" "waterproof/fade-proof", it's a roller-ball too.

A new test started just a few days ago. Northern window, rainy days until now (not much sun).

      @Texas42 Thank you. I myself have recently had the experience of cleaning out a Wing Sung 699, in which the iron-gall ink has been sitting for six months. No damage to the metal piston rod (whereas, in a Wing Sung 3013 vacuum-filler, it would have been corroded, turned green, and contaminated the ink in mere weeks), but there was a ring of colour at the far end of the barrel that wouldn't budge, and I found it impossible to unscrew the filling mechanism to clean the interior wall of the ink rese
    • Texas42
      Dang. You are a great friend!   One comment as a relative newcomer would be within the cleaning section: issues/differences in cleaning vacuum filler, piston filler in addition to cartridge/converter. I just cleaned out my Pilot 823 and while it wasn't particularly difficult I was a little paranoid about the drops of water that I could not get out. Perhaps this is something you are already including.   Anyway, great project and very thoughtful of you. I know it's a project fo

      Hi Smug Dill,   Nice project.  If it were me, I'd cover stuff like: - nib types available, i.e. styles, materials (SS vs gold), flex vs nails; - filling systems (I love the "thingie" comment) and how once can use them in practice (e.g. fill cartridges with a syringe); - pen body materials and their consequences (pen not balanced of too heavy and big for the hand); - and, whilst you've made it clear that you do not like vintage pens, a discussion of these beyond "I d
    • A Smug Dill
      Thanks for your input! Yes, not putting wood in the list of body materials warranting a mention was an oversight. I love pens with wooden bodies, but my main concern, or chagrin, is that I have not come across a wooden-bodied pen with a wooden cap that seals well. Actually, there is one, but it isn't really wood per se: the Pilot Custom Kaede's maple body is resin impregnated. All other wooden pens I have can dry out while capped and undisturbed; that includes several Platinum #3776 models.
