Favourite Black Ink?

[Thom.]

De Atramentis Document Black. A rich, deep beautiful well-behaved black that is also not only bulletproof, but bombproof.

This isn't the same as the archival black is it?

The problem with bombproof writing is you need bombproof paper.

Very similar. It is also archival, but in addition will resist bleach and chemicals that are used for "washing" checks and erasing signatures on legal documents.

That's only if you intend to set off a bomb in close proximity to the document.
Do people shoot bullets at bulletproof ink, me wonders.

That's why I would never call an ink bulletproof. Here's something I once wrote on the penexchange:

In this respect, the EG cannot come close to the nano document inks, which is why I would always recommend them for light use. As far as "classic" use of files is concerned, a milkmaid invoice and a quote:
9 months light test x 30 days = 270 days; x 12 hours of light = 3240 hours of light.
20 min file usage/day x 250 days/year = 5000 min : 60 = 83 hours per year.
3240 : 83 = 39 years.

If I use my cell phone to measure the light intensity directly at the window, as in the test, and at a distance of 1m from the window, as on a desk, then the difference in brightness is a factor of 20.

39 x 20 = 780 years. Other aging factors are also relevant.

We're going to do it all now.
We have the authenticity criteria of the standard here https://fpgeeks.com/forum/showthread...l=1#post391642
IG cannot resist hydrochloric acid and bleach, so they do not meet any standard https://www.penexchange.de/forum_neu...mittel#p289622

But for everyday use you don't have to suffer any disadvantages, such as increased cleaning effort, if you don't need the advantages, such as document authenticity.

Now we need a black/black IG ink!
(I don't believe I'll survive another 39 years, nor am I pouring bleach on my desk, so I should be fine with IG).

@Thom, for me the only importance with permanent inks is that when I write ideas, story lines etc or the shopping list t won't dissolve with a mishap of spilled water. Once my shopping list, written with Diamine Syrah a few snowflakes dissolved the list and made a mess.
I normally get rid of my notebooks after anyway

@Thom, for me the only importance with permanent inks is that when I write ... the shopping list ...

Great, the Declaration of Independence is written with Irongall, but I think it hung unfavorable in the light for a while. And that's #3 on my hottest stuff list
(#2 is my Swan Pen https://www.penexchange.de/forum_neu...t=2400#p366616).

The DOI also suffered some mishandling :

Interesting article (to me)

De Atramentis black Document or Archive inks are great and waterproof !

Aurora is my favorite, its just an excellent all around performer and very dark. Carbon Black is super, but I am leery about using it in some pens because, well, other folks are and I am not interested in having to take pens apart.
