Ink Review #557: Robert Oster Clearwater Rain


Today’s ink is Robert Oster Clearwater Rain from the 1980’s collection. I purchased my sample of ink from Pen Chalet.


The color:

Clearwater Rain is a pretty medium blue-teal.



In large swabs there is some pretty dark pink sheen.


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: Low-there was just a little bit of bleeding in the larger nib sizes on Rhodia.

Other properties: high shading, medium sheen, and no shimmer.

On Staples 24 lb copy paper there was a lot of feathering and just a little bit of bleeding.

Comparison Swabs:


Clearwater Rain is a bit darker than Pacific Ocean Teal, Marine and Torquay, but lighter than Aqua and Fire and Ice. Click here to see the Robert Oster inks together.

Longer Writing:


I used a Kaweco Sport Lagoon Blue with a fine nib on Tomoe River paper. The ink had an average flow.

Overall, I really like this ink. It’s a beautiful color, has some nice shading and sheen and an average flow.
