Ink Review #298: Robert Oster Purple Jazz


Robert Oster Purple Jazz is not an ink I'd heard mentioned before, so of course I had to find it. After doing some research I found out it used to be named Purple Soul, and has been renamed Purple Jazz. I purchased my sample of ink from Vanness Pens


The color:

Purple Jazz is a dark blue-violet. It's not quite blue, but it's not quite violet either-it rides the no man's land in-between. 



In large swabs it looks more violet than it does in writing. There is just a hint of red around the edges.


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: None

Other properties: medium shadingno 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 Pilot Vanishing Point Raden Galaxy on Tomoe River paper. The ink had an average flow.


Overall, it has some really interesting shading. It's right in-between blue and violet, which is an unusual color. It is pretty well behaved, but the dry time is a bit longer than most Robert Oster inks.
