Robert Oster Astorquiza Olive is a Bauer Inks exclusive. They had a table at the SF Pen Show, and when I saw some art that had been done with this ink I knew I had to give it a try.
Astorquiza Olive is dark, and somewhere between brown and green. I think it leans just a bit more toward green, but it can go either way depending on the lighting.
In large swabs on Tomoe River paper the ink more green and matte than on the Col-o-ring paper.
Let's take a look at how the ink behaves on fountain pen friendly papers: Rhodia, Tomoe River, and Leuchtturm.
Dry time: 10 seconds
Water resistance: Low
Feathering: Low-there was a little bit of feathering in the flex nib on Leuchtturm paper.
Show through: Medium
On Staples 24 lb copy paper the ink feathered in all nib sizes and had a little bit of bleeding.
I used a Kaweco Al-sport Rose Gold with a broad nib on Tomoe River paper. The ink had a dry flow. You can see in the last paragraph where I primed the feed a bit since it was so dry.
Overall, I don’t love this ink as much as I thought I would. The color is interesting and it dries quickly, but the flow is a bit dry for me.
