I love Robert Oster inks, and I know I’m not alone. I am especially fond of blue inks, so it’s no surprise that when Soda Pop Blue came out, I wanted some. Soda Pop Blue is a cross between a blue and a turquoise ink. And, like many Robert Oster inks, it has lovely shading and sheen.
I tested Soda Pop Blue on Maruman Septcouleur 75gsm paper, which is a smooth, true white paper. I used a Parker Premier fountain pen with a medium nib. This nib doesn’t exhibit much shading, but in broader nibs (see below) the shading is excellent. Soda Pop Blue isn’t as wet as other Robert Oster Inks I’ve tested, drying quite quickly. But that doesn’t mean that it’s too dry—in fact it flows nicely. The ink is definitely not waterproof.
My chromatography test demonstrates that the ink contains quite a bit of pink, turquoise, and blue.
Robert Oster produces so many beautiful blues. I did a comparison of the colors I have on hand so you can see the subtle variations. The closest match to Soda Pop Blue is Bondi Blue. But do you see that Blue Denim? Yum!
Soda Pop Blue is a gorgeous, saturated blue with stunning pink sheen. I used my Handwritmic Brody Neuenschwander Ruling Pen pen on Midori MD Cotton paper with excellent results as you can see in the photo below:
