I received a sample bottle of the new Aurora Blue-Black, kindly sent to me by Kirit Dal, Aurora UK, and here's one of my short reviews. There are plenty of other reviews where swabs, pictures of the bottle etc have been included, so I'm just concentrating how it looks when written with.
The ink is in an Aurora 88 large with F nib. It's smooth, flows well and even with that nib, exhibits some shading.
I've only compared it to a couple of my 'blue-black' inks that, in my opinion, show close similarities. There are many others out there that might look similar as well, but might not have the words 'blue-black' in their names. Likewise, there are many called 'blue-black' that bear no resemblance to the Aurora.
Therefore, I've not spent the time writing samples of another dozen or so of my inks for this simple review.
I also did a simple soak test, using my usual method. The paper was soaked for 30 minutes then rinsed for about 15 seconds before drying.
As you can see, there is still a very reasonable amount of legibility from the Aurora Blue-Black, without the 'run' of others. I included the Noodler's Black as a 'control' comparison.
So to sum up: it's a great ink and will fit into the market nicely, in my opinion. It should be available from the usual UK retailers soon, if not already!
