It's the last day of blue black ink week, so I thought I would finish the week out with a shimmer ink. I got a bottle of Robert Oster Black 'N' Blue, thinking that the ink would be black with some blue shimmer, or even blue-black with some shimmer, but surprise! It's actually a dark green ink with blue shimmer. I purchased my bottle of ink from Pen Chalet.
Black 'N' Blue is a dark green-black with bright blue shimmer.
In large swabs there is a ton of bright blue shimmer.
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 feathering and just a little bit of bleeding.
Ink swabs for comparison, left to right (top to bottom for mobile RSS): Birmingham Gibson Field, Robert Oster Black 'N' Blue, and Robert Oster Schwarze Rose. Black 'N' Blue and Schwarze Rose are very close, the main difference is that Black has blue shimmer, and Schwarze has copper shimmer. There is also a price difference between the two-Black comes in a 50ml bottle for $25, Schwarze comes in a 15ml bottle for $13.50.
Overall, it's pretty close to RO Schwarze Rose, just with a different color shimmer. I was very surprised that this ink is actually a dark green, but it's still pretty well behaved.
