It's new releases week, and today's new release is Robert Oster Thunderstorm. As soon as I saw a swab of this ink I knew I had to give it a try because it looked amazing. I purchased my sample of ink from Vanness Pens.
Thunderstorm is a beautiful dark blue black. It is the color of the sky during a thunderstorm.
In large swabs there is some pretty maroon sheen, which is interesting because the sheen on the col-o-ring swab looks green.
Let's take a look at how the ink behaves on fountain pen friendly papers: Rhodia, Tomoe River, and Leuchtturm.
Dry time: 30 seconds
Water resistance: Low
Show through: Medium
On Staples 24 lb copy paper there was some feathering in every nib size as well as a bit of bleeding, so it's not an ink I would recommend for cheap paper.
I used a broad Pelikan M600 Turquoise on Tomoe River paper. The ink had a slightly wet flow.
Overall, I love this ink. I love the color. The shading is great and has an average dry time. I think it's one of my new favorite blue blacks.
