Aurora inks come in three basic colors: blue, blue black and black. The bottle holds 45 ml of ink. Inks can be also bought in cartridges.
For many years Aurora wasn't interested in expanding their color range. They seemed to think that Blue and Black are able to fully satisfy fountain pen afficionados needs. The market changed, hundreds of new colors were created, new ink makers appeared and Aurora teem decided to make a bold move and offer new exciting color, unlike any other on the market * - blue black. It's a breakthrough moment in Aurora history. Who knows, maybe they'll dare to offer green or red soon?
While I'm not biggest fan of blue blacks, I tend to use them from time to time. Kyonooto Aonibi is one of my favorite inks ever but it's not classic blue black. I was interested in trying new Aurora ink (on the other hand I'm interested in trying any new ink). I bought a bottle and used it for few weeks in four pens. The results are good.
To put it shortly - it's an excellent fountain pen ink. You may not enjoy the color but the behavior and smoothness are first class.
The color is saturated and quite deep, the ink flows nicely and lubricates the nib in a satisfying way. level of saturation is satisfying but not crazily intense or overwhelming. There's some shading - I guess that in a right pen it can be quite intense. I haven't observed any feathering even on Moleskine (a synonyme of crappy paper). Some bleedthrough was experienced only on Moleskine (crappy paper).
Drying time is reasonable (10-15 secs on Rhodia and alikes).
Additionally it's fairly water resistant ink. Well done Aurora! I hope that you'll offer some new colors.
