Ink Review #2346: ON Inks Purple Heartwood

ON Inks is a new-to-me brand that I’m excited to test out. This bottle of ON Inks Purple Heartwood was given to me by a pen friend so I’m unsure of where you can purchase some.

The color:

Purple Heartwood is a deep unsaturated violet.

*For my swab cards I use a Col-o-ring by Skylab Letterpress, a medium Pilot Ishime and a Mabie Todd Swan.

Swabs:

In large swabs on Tomoe River paper the ink has some shading.

Writing samples:

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

*For my writing samples I use:

• EF Pilot Vanishing Point

• F, M, B Pilot Ishime

• Vintage Mabie Todd Swan (flex nib)

• Rhodia Goalbook

• Taroko Enigma notebooks (68gsm TR)

• Leuchtturm A5

• Pen & Gear Paper from Walmart

Dry time: 30 seconds

Water resistance: Low

Feathering: None

Show through: Medium

Bleeding: None

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

On 20 lb copy paper the ink had some feathering and bleeding in the larger nib sizes.

Comparison Swabs:

Purple Heartwood is less saturated than Diamine Music Vivaldi. Click here to see the purple inks together.

Longer Writing:

I used a Brooks Charleston with a medium monoc nib on a Taroko Enigma notebook. The ink has a very dry flow.

Overall, I enjoyed the color but it’s too dry for me to use in long-form writing.
