Have you ever noticed that it can dry into little hard pieces, almost like lint or little solid flecks but when that's rewetted it turns back into the ink. Is that the phenol?
Maybe this tendancy is what would clog up peoples pens in the old days. The stuff isn't really sitb-- just some wierd property of the ink but it can be messy.
i haven't tried to rehydrate those flecks. I don't know for sure what the chemical was that made Penman unique. Phenol is pretty volatile I would think but what would be left behind from it's evaporation might be what holds the dye together in flakes vs. dust. would love to know.
i do think that if the USPS actually knew what was in the Penman inks I've had shipped to the US from other countries... they might have gotten on my case about it.

The stuff does smell pretty strong. At least, all of my bottles do.
and yes - i have looked and looked for a green that matches Emerald and found none. I'm going to try mixing some of my green inks with other colors to see how close I can get. Sherwood and J. Herbin's Ivy Green (since I can't remember how to spell the French name) are close but not there. Sherwood is too blue, J.H. is too green and too light.
but some mix of this that or the other ink might come close. I have asked Nathan a couple of times if he could duplicate Emerald precisely and have never gotten a response. I would expect one would have to have specific equipment to measure light reflective/refractive qualities of the ink to "reverse engineer" a new Emerald.
And frankly, if he could accomplish that Eternal or otherwise, I *would* pay for it.
