Bic Cristal Inks Get Testing

We tested these 8 Bic Cristal pens to see how ballpoint ink holds up to 6 months of sunlight. Blue, Pink, Green, Black, Grass-Stain Green, Purple, Turquoise and Red.

During my last visit with Ink-Fast Donn at the D.C. Pen Show in 2019, he said he was starting to test ballpoint inks to see how well they hold up to UV light.

Last summer, I discovered a collection of the famous and commonly used Bic Cristal ballpoints in my fencing gear. I taught a wonderful group of teens and tweens advanced competition maneuvers and strategy, and to help them remember their lessons and opponents, I insisted they keep “Diaries of Doom” and “Tomes of Terror.” To help personalize it more, I handed out colorful notebooks and pens.

Armed with 8 colors (blue, pink, green, grass-stain green, black, turquoise, purple and red), I created a sample on Rhodia paper and taped it to a sunny window of my home at the end of August. I took it down at the end of February and was surprised by the results.

This photo doesn’t really do full justice to the sample set and proof set. The blue doesn’t look as blue as it does in real life.

Surprise #1 to me was that the black ink faded. With fountain pen inks, you can generally count on black to be the most stable and fade-proof. While it didn’t fade away entirely, it had issues.

Side by side comparisons showcase the effect of 6 months of sunlight on Bic Cristal inks.

Surprise #2: Blue! Blue fountain pen inks fade something fierce under the withering sun. Bic Cristal blue got stronger! It lost some of its blueness and turned blacker, but it held on defiantly under the sun’s gaze.

Surprise #3: Grass-Stain Green didn’t fade as much as I thought it would. It faded a little.

Red and purple faded the most. Green, turquoise and pink faded a little, but survived okay.

Reflecting on this experiment, for some reason, I always assumed oil-based ballpoint inks would be far more permanent than water-based fountain pen inks. Yet, their chemical compositions all have their frailties. Some ballpoint colors react differently than fountain pen inks, but that shouldn’t surprise me as much as it did.

More Ink Tests with Donn

Donn D. shared this new set of ink fast tests he made in 2018. Look how well Cross inks hold up!

Ink Guru Donn D. and I ran into each other again at the Chicago Pen Show a week ago, and I was pleased to see he had some new ink-fast tests to share. This batch is concerned with more fountain pen inks, and I was surprised to find great results with the Cross inks. Who knew? So often happens that Cross gets written off as a boring legacy brand. They make a lot of good ink and surprisingly good pens, in spite of their ubiquity on the scene here in the States.

Much of my conversation with Donn revolved around the fact that ballpoint inks are more susceptible to U.V. light than previously thought. He has found some fade out just as poorly as fountain pen inks. Given ballpoint inks are formulated with oil as a base, this surprised me. As thicker inks, I thought they’d last longer. With any luck, Donn will share those ballpoint ink results with us one day.

In the meantime, enjoy these great tests with fountain pen inks. Click the image to see a bigger version.
