For a brown/black, has anybody thought about iodine? It makes a nice color when it reacts with paper. My Sheffer Viewpoint also seems to like it. Is thers anything I need to steer toward or away from?

I would be nervous about iodine because it is an oxidizer.

 

It seems like I read about iodine and gold reacting with each other somewhere. Not so sure about stainless steel.

medical stainless steel should have no problems on Iodine... now the bigger question is the quality of the stainless steel

Several years ago I posted a test using a betadine prep solution as an ink. It was a pretty neat reaction to watch on the paper, but fairly rough on pens. Clean any pen soon after testing.

Please consider the following before using iodine in a fountain pen. Iodine crystals will not dissolve in water. They must be dissolved in alcohol. Evaporation of the alcohol may leave crystals which could clog your nib or feed. These would need to be re-dissolved or flushed with alcohol. I do not know what the effects might be on a sac, piston, etc. It is probably best to use a dip pen for this. Good quality stainless steel may be OK but rinse it well when finished. Iodine like chlorine and bromine is corrosive. A glass dip pen may be best.

I know it's been awhile. My test subjects are a Sheffer Viewpoint and a Manuscript Dodec with an iodine tincture. Both seem to handle alcohol, and the tincture well. They have a plastic (I guess HDPE) feed, nilon cartridge, and a decent nib that so far remains unblemished. I also have backups.

Also, I have some Lougl's Iodine standing by. ;)

Iodine is giving me a nice invisible black (black on paper, hard to see on nonpaper items, including my skin), but has turned red in one of my pens-even in the cartridge. I'm not sure what compound I wound up with. ICl is ths only possibility I can think of, but I haven't had the bleach near this pen. I guess when I washed it, the water utility may have dosed, but I wouldn't figure that would be enough to make it that red. Any other ideas on what may have turned my iodine red?
