Platinum’s 2017 release of six colorful iron gall inks, called the Classic Line, has made me very happy. I love iron gall inks for fountain pens, and appreciate the gentler ones, which I call “modern iron gall inks,” after KWZ Ink’s low-maintenance iron galls.
The new Platinum lineup seems very nice, and very low-maintenance. There’s an overview of all six here. I’ve used three of these on an extended basis, and reviewed those three here: Citrus, Sepia and Cassis. I got my samples from Dan Smith, the Nibsmith, who sells ink as well as pens, luckily for me.
I’ve recently been testing one of the Platinum Classic inks — Cassis Black — for an extended time in a Pilot Plumix fountain pen with a stainless steel nib. I wanted to really see just how safe these inks are with any pen. To see if the ink would react with the pen’s stainless steel nib, or clog or stain, and if so, how long would it take.
