On Permanent Ink, Permanency And Safety

[h.farmawi]

I believe it used to be an IG back in the 50ies or so. But now it is not...

 

Not sure though....

 

Maybe I will call Pelikan, I speak German too, and ask about it...

 

I will let you know

that would be great , Thanks !

I've found R&K Scabiosa and Salix to be fine in my pens (both are Iron Gall, and ard FP Friendly), worse case scenario is that they stain the edge of the converter or barrel a little, but a little soap and a q-tip can take care of it. Probably not ideal for demonstrators. Only pen I have it in currently though is a $15 Nemosine Singularity Demonstrator with a Goulet 1.5mm (steel) stub nib. Starts right up for me. I think R&K's method is something like a cold press which doesn't have as much of the same adverse effects as older IG ink, but not 100% sure on that.

 

I think the only completely permanent ink I use on a daily basis is Noodler's Black Eel, waterproof, bleach proof, laser proof, forgery resistant, etc etc. (got a few water-resistant inks, but none of them seem to hold without running at all like the black eel).

Sailor kiwa guro is technically soot as it uses carbon nano-particles, however it is safe for use in fountain pens. Also, nib corrosion on fountain pens caused by iron gall ink was down to old ink formulas being excessively acidic, which is not a problem with modern FP-safe IG ink, and mild steel nibs. Modern stainless steel is safe with IG ink, as is gold.

 

Bottom line is: If an ink is marketed as safe for fountain pens, it's safe for fountain pens. I'd be inclined to clean pens used with IG or nano particle inks after every couple of fills, but other than that they're fine. Problems arise if you try using inks designed for dip pens in a fountain pen.
