Today’s ink is Robert Oster Bass Straight from the 1980’s collection. I purchased my sample of ink from Pen Chalet.
Bass Straight is a medium dusky blue.
In large swabs the ink has some pretty shading and just a tiny bit of pink sheen.
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 a lot of feathering and some bleeding as well.
Bass Straight is closest to Organics Studio Copper Turquoise. Click here to see the Robert Oster inks together.
I used a TWSBI Eco Transparent Blue with a medium nib on Tomoe River paper. The ink had an average flow.
Overall, it’s another great blue ink from Robert Oster. It’s a pretty color, has some nice shading and just the tiniest bit of sheen.
