I now have a few (modern) pointed nib, flexible (semi-flexible at least) pens. The most recent are a promising Conklin Omniflex and the best Fountain Pen Revolution" can offer. Im aware that, currently, nothing is as good as a dip-pen, antique, or "nib-meistered" option, but the former is unsuitable for my jacket pocket, and the latter are beyond back pocket capacity. My dream is to develop a reasonable copperplate using something from my pocket. So, I have the pens, but what ink might someone suggest. Pigment is clearly a poor choice due to clogging, and Im fairly clear the ink should be fairly "wet" in the sense of flowing well. Also, whilst there is a whole other hobby in collecting inks out there, I prefer to restrict myself to black: I write for my students and if I start being too adventurous I will end up receiving fluorescent homework! So, in a nutshell, what do members think is the best black ink for fountain pen copperplate? (Apologies if this is in the wrong section. Administrators should feel free to move it about as required.)
