Ever wondered about india ink or calligraphy ink versus “fountain pen” ink? Meg posed this great question about just such a topic.
… I’ve been refilling the Pilot Petit1 cartridges with some bottled india ink that I have left over from dabbling in calligraphy. Ink seems to be pooling in the thready area (like on the Preppy), am I doing something wrong?
Calligraphy and india inks are not designed for fountain pens. They can be corrosive and can dry to be waterproof which, in the pen overtime, can cause it to clog. Some calligraphy inks are also thicker and gooier meant for dip pens so that the ink sits up on the paper and does not bleed into the paper fibers. This characteristic is particularly handy when you are using very wide italic nibs.
The good news is that if you did really jam up a pen, it is a Pilot Petit 1 and not a pricier pen.
I would recommend purchasing some ink specifically designed for fountain pens like Noodlers, Diamine, DeAtramentis, J. Herbin or any fountain pen manufacturer that sells ink (i.e. Lamy, Waterman, Parker, Kaweco, etc). These inks are specifically designed for fountain pens so that they flow easily through the feeder. These inks are not waterproof which means they will not dry and cake up the feed of nib. If fountain pen ink does dry in a pen, usually a good soak in water will clear it up, though it might take awhile.
In the future, save the calligraphy inks for dip nib pens. Since the nibs in most dip pens can be easily swapped out for less than $5, when they do corrode, its not such a big deal.
Thanks for the great question, Meg!
