Maybe someone could convince Nathan to replicate it. Does anyone know why he doesn't make an iron gall ink?
Nathan, it would appear, doesn't like acidic inks. Most of the Noodler's inks are pH neutral.
There are good reasons why iron gall inks can be problematic for archival purposes, due to the acid eating holes in the paper. (This may depend on the amount of iron gall compounds in the ink.)
Iron gall inks are probably also not as resistant to forgery as Noodler's bulletproof inks, which are based on dyes which react with the cellulose of paper.
Also, take a look at the Noodler's site to see what iron gall inks can do to aluminium foil! I am hazarding a guess that one of the inks mentioned may be Mont Blanc blue-black ink. (I may be wrong.)
Iron gall ink in the past reacted with the medium of the paper in a few different ways. The first was the oxidation of the soluble Iron (II) Sulphate to Iron (III) sulphate which attacked the cellulose of paper, excess sulphate in poorly mixed ink was the leading cause to paper degradation, high acidity, humidity and temperature accelerated this process by being catalysts and that's what created holes in the paper. Though not definite, Iron gall inks with well balanced Iron(II) sulfate, and which are not as acidic appear to persevere better than those that are not. One researcher even found acid free paper to be degraded, though the key here is if he was using poorly made ink with excess iron (II) sulfate or not, which is not made clear, and which others point to in criticizing his original claim that all iron gall inks will degrade paper.
I believe in using modern formations from Diamine, Lamy, and R&K, you have two things going for you, you have well formulated iron gall ink, which lessens the presence of excess sulphate, and two, you have acid free paper widely used which helps to decrease the acid present. The high humidity, and temp is environment dependent of course, but if you hope to preserve something, I would think you would be reducing the presence of these two things!
The one problem with the aluminum test is very few pens of any quality are made with aluminum parts, and so unless you are set on using a 10 pack of knock offs you got for five dollars, the quality of stainless steel nibs is such that the acid from fountain pen friendly iron gall ink is a non issue, heck the stainless steel and metal parts of the knock offs maybe as good too, I just wouldn't trust they have a great quality control program. I have used Diamine Registrar's in two Lamy safari's for 2 1/2 years now with no degradation of the nib, and R&K Scabiosa in a Lamy Safari and P51 with no degradation. This doesn't mean you shouldn't be aware that after 2 weeks to a month a little precipitation can occur, but usually if used as a every day pen, a refill or two will happen before this time. if precipitation does happen, flushing it with a tiny amount of soap gets it ready to write again. I have never had a pen become clogged, it's simply not an issue as long as you maintain your pens.

FP Ink Orphanage-Is an ink not working with your pens, not the color you're looking for, is never to see the light of day again?!! If this is you, and the ink is in fine condition otherwise, don't dump it down the sink, or throw it into the trash, send it to me (payment can be negotiated), and I will provide it a nice safe home with love, and a decent meal of paper!
