I work in a regulatory chemistry lab so having basically everything resistant ink is a must for archival & forgery purposes.  Where I'm at we're under EPA regulations (vs. ISO or TNI) so it only says indelible ink.  The majority of the inks I use are Noodler's bulletproof inks & have been approved by our QA/QC officer.  Since Noodler's inks are not ISO or anything else certified I decided to do my own tests with some of our common solvents in the lab in case an auditor ever asks about it.  My test wasn't anything super scientific but should be enough to show anyone the permanency of the ink.  While I was at it I figured it's nice to share my results with you.  

 

The test:  I filled a beakers with 6 common solvents we use in our lab.  The solvents are Hexane, Acetone, Ethyl Acetate, Methylene Chloride, methyl tert butyl ether(MTBE), and Methanol.  I wrote the name of each ink on plain copy paper and let it dry overnight.  I then let it soaked each piece of paper in the corresponding solvent for at least 1 minuet.  During the soak I agitated the piece of paper several times in an attempt to force the ink to wash off.  And for reference I wrote the name of the solvent the paper was placed in with a black Bic pen.  After soaking I removed the paper and placed it on the counter to dry. 

 

Edit: One other note, the ink labeled Noodler's Teal is a 1:4 mix of Bad Green Gator and Bad Blue Heron respectively.

 

This first picture is of everything before it was soaked in solvent.  And please forgive my bad handwriting as I was scribbling the names and wasn't worried about penmanship.

Now for the results:

 

This picture is after the paper was soaked in solvent and allowed to dry.

 

In most all cases the ink stayed put regardless of the solvent it was placed in.  Noodler’s Zhivago, Lemontov, Blue-Black, Air Corp Blue Black, and Dostoyevsky had very slight running when placed in Methanol but nothing significant.  The most significant result was Tolstoy.  It remained intact in Hexane and MTBE, Had slight feathering out an Ethylacetate and nearly washed out all together in Acetone, Methylene Chloride & Methanol.

I once hung HoD in a north-facing window long enough for the paper to start to yellow.  It lost absolutely no color.

 

Try soaking or boiling them in ammonia, if you will; I'd appreciate that.

 

And I'm sure the Ink Comparisons forum would appreciate this.

Thank you very much for sharing this experiment! The colors being compared on those sheets is also a great reference. Now considering getting a bottle of Lermontov. Did Lermontov used to be violet and then reformulated to blue?

Thanks for doing this.  Proves what I've thought (and said) all along -- Kung Te Cheng is pretty much EVERYTHING proof!  Good to know about 54th Massachusetts and Heart of Darkness -- I like those as well.

Interesting tests  :thumbup:
I guess we can’t really quibble with the makers’ claims about the robustness of these inks :)

 

Has anyone here previously posted images of similar tests performed with the solvents that are commonly available outside of labs (ethanol, bleach, ammonia, and sodium hydroxide)?

That is cool! I've only done sun fading tests.

Very impressive evaluation of the "bullet-proof-ness" of these inks. I liked the details and the images.

Thank you so much.

To all -- Stay well and safe in these challenging times
