Ink Review: Robert Oster Midnight Sapphire and Astorquiza Rot

May 20, 2017

Robert Oster Signature Inks from Australia is one of the most prolific ink brands on the market right now, seemingly introducing new colors on an almost weekly basis. I recently reviewed their acclaimed "Fire and Ice" ink, and ended up enjoying it despite the fact that I typically avoid highly saturated inks with a lot of sheen. Every Robert Oster color that I've tried has behaved so well - both in pens and on paper - that I'm making an effort to try as many of the inks as I can. A huge thank you to Vanness Pens for providing me with the two ink samples featured in this review.

Robert Oster Midnight Sapphire

The Midnight Sapphire struck me as a touch flat. Maybe it's a bit too gray for my taste? 

While Robert Oster Midnight Sapphire is an excellent ink that can serve as your everyday "blue-black," this color left me wanting something more. I guess the "sapphire" reference led me to expect a bit more blue "pop" than this ink delivers. Once it dries, it actually turns out to be a fairly standard dark blue-black ink with grayish undertones, though it does exhibit some nice shading, especially in a wet nib on Tomoe River paper. 

Robert Oster Astorquiza Rot

Astorquiza Rot is a gorgeous red ink, just not what I expected, and not a color I currently need in my collection. I didn't find quite as much shading as with the Midnight Sapphire.

I would characterize Astorquiza Rot as a darker red with hints of brown, orange, and/or copper. I originally picked this sample because I hoped it could serve as a replacement for my rapidly dwindling supply of Montblanc Alfred Hitchcock Red. As it turns out, the Hitchcock doesn't have nearly as much orange and might have a touch more black. A better comparison to the Astorquiza Rot would be Montblanc's latest William Shakespeare Limited Edition. The search for a Hitchcock replacement continues! 

Robert Oster Astorquiza Rot (top) compared against three other red inks: Montblanc Alfred Hitchcock 2012 L.E., William Shakespeare Velvet Red (current L.E.), and the Diamine/Cult Pens collaboration Deep Dark Red. 

Takeaways and Where to Buy

While neither of these inks blew me away from a color perspective, that's more of a function of my ridiculous ink collection/hoard than anything else. I simply have too many other inks that are too close to these. That said, if you're looking for a nice standard blue-black ink with a fair amount of shading, Midnight Sapphire would be a solid choice. Similarly, if you're looking for a brick/blood red, Astorquiza Rot is a perfectly serviceable red ink that seems to be fairly low-maintenance, which can be rare with colors like red and orange. Both inks flow well, dry quickly, and didn't crust up or demonstrate any other "behavioral problems."  

Robert Oster's Signature Ink Bottle

You can purchase both Midnight Sapphire and Astorquiza Rot, as well as all the other Robert Oster inks, from Vanness Pens. I'm a big fan of Robert Oster's bottles: their tall-and-slim design makes them easy to store, and at $16 for a 50ml bottle, the price is right.
