Would people recommend using Rohrer & Klingner iron gall ink in a nice pen w/ gold nib (Pilot Custom 823)?
I've been really enjoying this R&K “Ebony” ink, and it would be nice to use it in my favorite pen. I hear R&K iron gall inks are pretty gentle and gold nibs are particularly capable of handling iron gall, but I want to be extra sure.
Also, the vacuum filler plunger shaft looks like stainless steel, so I would be worried about damaging that.
