Ink Review #1068: Robert Oster Australian Opal Grey

I can’t resist Robert Oster inks normally, but when I saw that Robert Oster released a new grey ink it was an insta-buy. I purchased my bottle of Robert Oster Australian Opal Grey from Pen Chalet.

The color:

AO Grey is a light grey with a purple undertone.

Swabs:

In large swabs on Tomoe River paper the ink looks more purple than it does in writing.

Writing samples:

Let's take a look at how the ink behaves on fountain pen friendly papers: Rhodia, Tomoe River, and Leuchtturm.

Dry time: 20 seconds

Water resistance: Low

Feathering: None

Show through: Medium

Bleeding: None

Other properties: medium shading, tiny sheen, and no shimmer. There’s just a touch of copper sheen in large swabs on Tomoe River paper.

On Staples 24 lb copy paper there was some feathering but no bleeding.

Comparison Swabs:

AO Grey is less saturated than, but similar to Colorverse Anti-matter. Click here to see the Robert Oster inks together, and click here to see the grey inks together.

Longer writing:

I used a Pilot Vanishing Point Galaxy with a broad nib on a Yoseka A5 notebook. The ink had a dry flow, which made the broad nib feel more like a medium.

Overall, I love the color and shading but the flow is a bit dry for my taste. I’m planning to add a drop of ink additive like White Lightning so it flows better the next time I use it.
