pigment

Rating: 4.0 February 8, 2011 Platinum Pigment Rose Red is my first experience with pigment-based fountain pen inks. The vast majority of fountain pen inks are dyes dissolved in water or other solvents, but pigment-based inks have micro-particles that are suspended in solution. They are specifically formulated for fountain pens, with particles small enough and solvents benign enough that they won’t clog the feed or interfere with the capillary action of the nib.
