Choosing the Ink

 

When choosing fountain pen inks always choose water soluble dyes which allow for a continuous flow. Pigment-based ink and India inks contain suspended particles which can clog pen capillaries. The same goes for any calligraphy inks.

If you’re looking to leave an indelible mark, iron-gall inks - used by the likes of Leonardo da Vinci, Johann Sebastian Bach and Hans Christian Anderson - will do the trick.  In earlier times due to iron content, this substance was known to corrode paper the same way metal oxidizes when experiencing varying climate changes. These days using neutral pH dyes eliminates the problem.
