It's teal week! Let's take a look at Diamine Marine, the first ink I ever bought. I chose this ink as my first since I was told it had amazing shading. I purchased my bottle of ink from Goulet Pens.
Marine is a beautiful light teal.
In large swabs the ink does not show any sheen.
Let's take a look at how the ink behaves on fountain pen friendly papers: Rhodia, Tomoe River, and Leuchtturm.
Dry time: 30 seconds
Water resistance: Low
Show through: Medium
Other properties: medium shading, no sheen, and no shimmer. There are a lot of inks in this color that have the same amount of shading this one does, so I don't know why it's always mentioned as the teal with the most shading. It has some good shading, don't get me wrong, but it doesn't have significantly more than other inks like it.
On Staples 24 lb copy paper there was some feathering and bleeding.
Ink swabs for comparison, left to right (top to bottom for mobile RSS): Robert Oster Marine, Diamine Marine, and Papier Plume Lake Michigan Summer. Click here to see the Diamine inks together. I actually love all three of these inks. Robert Oster Marine is the only one of these three that has any sheen.
I used a broad Pelikan M805 Vibrant Blue on Tomoe River paper. The ink had an average flow.
Overall, this is one of my favorite Diamine inks. It's well behaved, has a beautiful color, and some lovely shading.
