Sailor Sou Boku from Lamy 2000F on Oxford Optik.jpg

Yummy!   Souboku does best in a wet nib, IMO.  Thanks, @Mercian!

Full disclosure:
I made sure to follow the advice of an expert, and agitated the bottle before I filled my pen with this ink

"but iron-gall inks can ‘eat’ steel nibs,”

 

… while the solvents in some pigment inks are apt to compromise (certain?) nib coatings over an extended term. I've seen it with Sailor Kiwaguro and Seiboku, and I remember reading something about that with Diamine Forever inks recently.

Yikes!
Thank you for letting me know
I am now🤞that the platinum plating/gold body of my 2000's nib is not one of the interfaces that these inks can compromise.
Perhaps I ought to not use Sou Boku (should I be typing 'Souboku'?) in my Lamy 2000 long-term 🤔

I am happy to restrict it to only Edelstein Tanzanite if I am in a mood to use 'blue/black' ink in it.

 

And I do have some steel-nibbed pens that write with a similar degree of 'wetness' to the 2000 if I wish to lay down Sou Boku fairly heavily.

 

Your information is well worth adding to the post for which I took this picture (and the close-ups).
And it might be worth starting a thread to warn people of the potential danger.

 

Do you happen to know whether the nib-coatings that have been affected by pigment inks were e.g. gold-plating on steel, or were perhaps some of the newer (anodised?) nib coatings (e.g. the blue nibs on the 'monochrome' blue Parker IM and Cross ATX)?

I'm a scardy cat - none of the Sailor nano inks get used in pens with PVD coated nibs. Or pigmented inks left in any that are plated. Or iron gall left in anything. (Not that I have any strong iron gall inks.) I am probably missing out, but my fear of spoiled nibs has been stronger than my fear of missing out.

This was the thread: 

In my experience:

and I'm pretty sure it was Sailor Seiboku that ate the black PVD coating on the underside of the Z52 nib on my LAMY Studio Lx All Black.

How can I date a text written with a regular and usually pen so that microscopic devices can date it back 6 years?  It should be possible, and according to the site, I need the help of everyone in space to complete my research on radiation and pen ink in texts

What type lamp uvc or uva or infrared?

What distance from paper?

What watt/ hours be lamp?

Please answer me

Please

Thank you for those links, and for your further explanation

 

In future I shall keep Sou Boku (& Kiwa Guro) out of my pens that have PVD-coated nibs, and/or plated nibs.

I can use other inks in those pens, and other pens with my Sou Boku & Kiwa Guro
