Most Boring - On Emptying A Bottle Of Tsuki-Yo

[gmax]

No updates since last year?!

[KaB]

Indeed. I did empty the Lamy with the 1.5 But I filled it with Sailor Jentle Grenade to write the Christmascards. And I've taken a few days free...

[UDog]

You should post a writing sample alongside the bottle.

You should post a writing sample alongside the bottle.

 

Oh, some kind of proof?

[KaB]

finally emtied the lamy with the Christmassy sailor jentle grenade and refilled it with Tsuki-Yo. 23rd filling:

And as per repeated request, a writing sample:

 

 

 

 

The VAC text might be familiar to some. It's a French alternative to 'the quick brown fox' (running: take that old whisky to the blond smoking judge). The Lamy text might be new for most. It's a Dutch alternative to 'the quick brown fox'. And it's rather a special one since, obviously, it contains all letters of the Dutch alphabet, but even more: it uses every letter exactly once!

 

It runs 'lynx or fox picks (should have been 'pikt' = steals, but where else to drop the 'r') bra: bye-bye swimming-teacher!

Love this idea, great project.

Spent two hours going through this thread....totally worth it!

Makes me want to try this as new year resolution lol

[UDog]

Now that looks GREAT, KaB.

What color is that ink? Blue-black-ish?

I just discovered this thread today--so meta, I love it! On another note, it is really useful to see how many fills approx. it takes to get through a bottle of pilot irishizuku. Haven't even gotten to the label of a bottle I've had for more than two years.

Tsuki-yo essentially means moonlit sky, and that's how I see this- that deep, dark blue with hints of black that the sky turns on a clear, cold night, just before the sky gives the silver moon a black background.

Did you know Iroshizuku Tsuki-Yo has a sheen? I accidentally dropped a droplet on Tomoe River paper and it has a glorious reddish sheen to it.

I guess that makes sense cause Kon-Peki has a slightly pinkish sheen.

And 24th filling (the VAC)

For months now, I've been thinking that if I wanted an Iro blue-black, instead of basic Pilot BB, Shin-Kai was the one for me. However....

 

One of the things I did with Amber's ink fade spreadsheet was to make a list of every ink with at least one "good" or better result. Tsuki-yo has six "excellent" results, and five "good" results. Shin-Kai has none of either. And since fade resistance is one of my high-priority ink qualities, it looks like Tsuki-Yo should have been the blue-black Iro for me.

 

Nota bene, many inks submitted to Amber for her marathon fade tests were not issued fade resistance ratings because the windows they were in did not receive full sun. I'd dearly like to have those results regardless, either with or without notation that they received reduced sunlight exposure.

 

And given another FPNer's recent picture/scan of an ink fade sampler that was exposed only to indoor light, I have my doubts about the importance of full light anyway. For simplicity and ease, my next sampler will be hung in a window that gets no direct sunlight atall, because (unlike the window that does) there is no risk of condensation damaging the samples. And for grins, I'm going to use the HP Deskjet all-in-one inkjet printer to make the guidelines, instead of the Laserjet 1018, cos I want to test HP's inkjet ink for fade resistance too.

just 10 hours later: 25th filling. The Lamy 1.5

And given another FPNer's recent picture/scan of an ink fade sampler that was exposed only to indoor light, I have my doubts about the importance of full light anyway.

What is important is the amount of UV light received. Whether the light is indoor or outdoor doesn't matter. The amount of light is what matters, and the quantities received. And indoor sample will simply take longer to fade, not whether the ink would fade at all. And all the tests are only relative guesses. Of course, inks that are fade-resistant due to light after 6 months in south-facing sunny locations will obviously give a very good indication of their durability. Inks that had some degree of fading after that same time may be very suitable, because perhaps they only started to fade after 5 months. And that may still indicate very good durability.

 

The two criteria missing from the existing analyses are

 

1) the time=T that it takes for an ink/dye/pigment to start to fade

2) the quantity=X for the measurement of light received over T.

 

The other important element is a Control, a system of known rates of fading. This is typically provided by an ASTM scale, but can be approximated by the Blue Wool Scales. This is a card of wool threads, each set with a different dye that is known to fade at specific rates.

 

This is the only way to get an accurate measurement of the durability for an ink/dye/pigment. These tests are well known in artists paints, with manufacturers providing an indication of the ASTM ratings, I=considered permanent, II=very durable, III=acceptable, slight fading, IV=fugitive.

 

Until our tests are done in accordance with scientific principles, and reported accordingly, manufacturers can simply ignore the results since the customer will still purchase the ink based on it's beauty or some other factor.

26th filling (the VAC)

It would be more exciting if we could watch the ink dry on the page.
