A sheet of sample swabs of various popular fountain pen inks has been in my studio window since March 10. The samples I tested in that round are:
One month later, I posted the changes that occurred in that short time period. Today I took down the sheets and photographed them again. It's seven and a half months that they've been in the window, and a couple of the results I found surprising. Here's what the sheets look like now:
You can click that image to see a larger version. The left side was in my south-facing studio window. The right side was kept inside a box in a cabinet, to avoid light exposure completely. The biggest surprise was that Noodler's Baystate Blue completely disappeared! Well, okay, there are a few greenish bits barely visible here and there, but I'll bet within a month, those will be gone too.
The other big surprise is actually a good thing; Noodler's Kung Te-Cheng, one of my favorite inks to work with, has stayed exactly the same as far as I can tell. That doesn't mean I'd do fine art with it to hang on my wall, but it does mean I feel totally comfortable with using it in my sketchbooks and for other purposes too. All the rest of these colors either faded dramatically, had large color shifts, or both.
It's a well known fact that fountain pen inks should not be used for fine art. They are dye-based, rather than being pigment-based like paints, and those dyes are fugitive and not meant to withstand the long term effects of ultraviolet light. Still, some hold up much better than others. Even for use in my sketchbooks, I like to know where they stand. It is worth noting that the sheets on the right, which were kept in darkness, have had no problem with retaining vivid colors, so please don't get nervous if you've been using these inks inside a book. They should be absolutely fine! These tests only reveal what happens when an ink is exposed to sunlight. If the inks you've used are not exposed to light, then these results are irrelevant.
In April, I started another round of tests with 26 more colors. It's hard to find the time to post them all at once, so I will be posting those results tomorrow and the next day. Tomorrow I'll be posting the results of::
