Ink Review #294: Robert Oster Purple Rock

It's purple week! We are starting off with Robert Oster Purple Rock. I purchased my sample of ink from Vanness Pens. 

The color:

Purple Rock is one of those inks that looks a little bit different on every paper. On the Col-o-ring it looks more medium purple.

Swabs:

In large swabs the ink turns looks more of a dusky blue purple. There's just a little bit of pinkish red sheen on the edges. The sheen is not visible 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: 40 seconds

Water resistance: Low

Feathering: None

Show through: Medium

Bleeding: Low, mainly in the flex nib on Tomoe River paper.

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

On 20 pound copy paper the ink performed well, no issues that I noticed.

Comparison Swabs:

Longer writing: 

I used a broad Pelikan M805 Ocean Swirl on Tomoe River paper. The ink had an average flow.

Overall, this ink really does look different on every paper. On the Col-o-ring it's more purple, and on most other papers it's more blue-violet. It has some lovely shading and behaves pretty well. Give it a try, you might love it.
