Notes on ink.
There are several main types of ink.
1. Water soluble – like you get in stationery stores, like J. Herbin, Waterman or Quink.
2. Document ink or Pigment ink, like DeAtramentis Document Ink, or Sailor Pigment inks from Japan
3. Permanent ink, like acrylic ink or Indian ink. Do not use Indian ink in fountain pens, ever, ever, ever. For these kinds of inks use only dip pens or reed or bamboo pens or sticks carved to a point. If you put Indian ink or acrylic ink in a fountain pen it will turn as solid as a rock and will destroy your ink feed on your fountain pen and quite possibly also your nib which you likely won’t be able to extricate and you will therefore destroy your pen. This will make you very sad.
Methods of cleaning your pen:
If you really want to give your pen a good cleaning, you can run the feed under a tap of warm water with a fairly good force. Then, I also use a baby‘s ear syringe which you can buy at many pharmacies, for plunging out clogged ink inside of the pen’s ink feed. Note: never use these in baby’s ears. (I don’t know why they even sell them for that.) The little bulb is great for creating pressure to get the extra globby ink out of your pen. Another good trick is to put a ball bearing of some sort in your ink bottle: that will break up any globs before you fill your pen.
I use a cleaning solution that is called by Rapido-eze. Made by Koh-I-noor for technical pens and calligraphy pens. Or, you can get a solution called Pen flush from Goulet pens in the United States, or possibly Duly Noted here. If that doesn’t work, you may have to disassemble your pen which takes a little bit more determination. I use a little bit of rubberized kitchen shelf paper from the Dollar store to get a bit of a grip on the pen nib and ink feed its installed into. But this is not for the faint of heart, and you could possibly damage your pen if you don’t pull straight out.
It’s a good idea to flush your pen out every time you reload ink, but sometimes when you’re in the middle of a drawing you’re really not going to have time to do this. So plan on doing it as regularly as you can. When it comes to dip pens, I like to rinse the nib with a bit of rubbing alcohol on paper towel.
Other “ink” alternatives
You can also use other things to paint or draw with, everything from wine to coffee. There’s also a wonderful artist called Dylan Sera on Youtube who reminds me of a hobbit from middle earth who forages in the forest for twigs to make pens. He also makes his ink from things like walnuts and berries, which he demonstrates, called Ink Naturally with Dylan Sara.
