Bill and Disciples....
... okay, I'll buy that off you. I don't even have any Noodler's (because nobody sells them here), it's just that I have heard of 1-2-3 complaints and/or questions regarding Noodler's "safety", but I've never heard anything like that about the other two inks I mentioned.

As one of the "disciples", I most humbly apologize for not mentioning the Pelikan and Aurora inks, however the original question was asked about India ink and its suitability for fountain pens, thus, my writing yesterday was only as a comparison to the qualities of India Inks and not a comparison of all black inks.
Yes, Pelikan and Aurora are both very nice inks. Pelikan 4001 black was for many, many years my predominant black ink of choice. Aurora ink was gift in the late 90's and somehow it ended up in my desk drawer at work. Anytime I ran out of Pelikan at work I would fill up with the Aurora. However, I found the Aurora to be a little on the pale side and did not lay down a line as rich as the Pelikan. Had I not found Noodler's ink, I would probably still be using the two in the same way.
However, when comparing these inks to the density of India ink, there is no comparison. IMHO. India ink is the blackest of blacks and has a permanence beyond compare and while working well in technical drawing pens and dip pens, it is by no means an ink for a fountain pen. For myself, I find the closest ink to India that works without damaging fountain pens (if cleaning is regularly performed) is the Platinum Carbon Black. A safer, for fountain pen, ink would fall into the Noodler's line for it's richness and bulletproof/waterproof qualities, hence the reference to Heart of Darkness which to me appears to be the darkest pure black in the Noodler's line. (I have as yet to try all of them in personal use.)
Then there is the issue of pH factors. Aurora = 4.3, Pelikan=8.2, HOD=7.4. Aurora is acidic, Pelikan is slightly alkaline and Noodler's HOD is neutral.
Of course, these are just my personal preferences and do not dictate how others feel about the topic.
It is sad that you are not able to obtain Noodler's ink in your country especially when Germany has shared so many good things with the US and the world. I would most happily provide you (Mike only) with a couple drams of Heart of Darkness if you would be willing to pay for shipping!
Have wonderful Inky Day!
