This information is to try and
help new fountain pen enthusiasts, and clarify some commonly held misconceptions
about fountain pen ink. All fountain pen inks are water based, and all
components are completely water soluble.
With few exceptions most modern inks are synthetic aniline dyes and their salts. Other components added are for adjusting the surface tension properties, i.e,. surfactants, viscosity, e.g., ethylene glycol or glycerine, antibacterial properties, e.g., phenols, or pH. It is perfectly safe to experiment with using virtually any ink in any fountain pen, though demonstrators or clear barrel pens can be stained by some inks on long exposure. The staining is due primarily to the chemical nature of the particular ink, including it's pH and its dye concentration. The dyes used in purple inks in general also tend to stain. As the colour of most dyes are dependent on the pH, some inks can look different on different papers, as these can differ in acidity and buffering capacity. |
