    I like the color, but I've gotten horrible crud creep with this in the one pen I've tried it in so far, a vintage Parker Duofold. Normally, this pen works fine with other inks, but with Ancient Copper, brownish-blackish sludgelike stuff accumulates at the base of the nib, especially from between the nib and the feed where they meet the section, and also along the slit. When I cleaned it off, it was back after a few days. I'm going to limit my use of this ink to modern converter pens for short periods of time, making sure to flush whatever pen I use as soon as I'm done.

    Here's a photo. Sorry I don't have a decent closeup lens.

    There are several posts about inks that contain this particular dye forming stuff like this on FP nibs after a while. I also mention it on my original review sheet.

    It's not mould, but merely the ink losing water and drying out back into it's original powder. If you like to use that colour ink maybe you should not fill your pen fully and use up the part fill quickly. Or only use it in pens that have more airtight caps.
