That's why I want to try the gouache. It's a water based artist's pigment that comes in gold, silver, bronze, etc. If I can dilute it enough to flow through the pen AND still shine, mixed with FP ink for color and adhesion, it might work.
Hmmm. If you dilute gouache enough, it works like regular watercolor paint (in fact, when I took a watercolor class in college we used Winsor-Newton gouache). That sort of precludes the shine, IMO.
Not sure how it will work in FPs; I did do a calligraphy job years ago for a former co-worker, addressing wedding invitations with a gouache mixed to match the color of the invitations (the envelopes were dark navy blue), but that was with a standard Speedball pen and nib.
I recent got a Pelikan 100 on Ebay with an italic nib. When I inspected the nib there was this stuff on it that looked a lot like dried paint, which reminded me a lot of that old calligraphy job, since it was a similar color, and when I flushed the pen out with ammonia solution what came out was bright orange (flushing with just water netted something that looked like a dark purple-blue in, so the bright orange was something of a shock). I'm wondering now if the former owner did do something like what you're suggesting. The pen appears to write okay (I have Quink Black in it at the moment), so you *may* be safe using regular gouache. Not sure about metallics though. And even then, I would only try it in something you don't mind ruining for the sake of "science", like a Platinum Preppy or a refilled Pilot Varsity turned into an eyedropper pen. Especially the latter, because they're designed to be disposable in the first place.
Okay, now you've actually got me interested. I have a couple of empty Varsities, and I may try playing around with stuff like shell gold and gouache paint in a few weeks (too much on the plate already until after DCSS). If it fails, well, they were dead anyway (and can tell the hubby that I have started paring down the pen stash... ). Not sure I'll get an opalescent or pearlescent effect, though. In the meantime I will try to talk to people I know that do calligraphy and illumination, especially some people who teach various sorts of classes in traditional techniques such as tempera painting. But again, that won't be immediate.
