During a recent trip to The Hague I bought a couple of Akkerman inks at their store. After a fresh supply was brought in from the store room (apparently these inks are popular) I could test the inks using a toothpick. I already reviewed Ruisdael’s Stormachtig Blauw; this review deals with #9 'Steenrood van Vermeer’. The Steenrood (stone red) refers to the colour of bricks, and the picture by Vermeer illustrates the warm, mellow colour of those bricks, and so does this ink.
As I said the ink catches the colour of bricks very well, a warm reddish brown (or brownish red, if you prefer). I like this colour and this ink in general. A good flow, nice and wet. Drying times on Leuchtturm and a fairly wet Lamy M are between 10 and 15 seconds, but in real life it feels faster. What’s even better is the shading this ink shows. (again apologies for my handwriting)
On all combination of nibs and paper I’ve observed shading, Shading great, sheen none. On Leuchtturm paper
The ink takes a little time to dry (feels less than it actually does), after that it sits pretty solidly on the paper. This ink is not waterproof. A couple of drops of water sitting for 1 min, and next to that the results after keeping the paper under a running tap. Most of the ink is washed away, leaving just a vague impression of the ink
I like this ink, its mellow colour, shading, and nice behaviour, but it will not be my main ink (for that I have a pool of blue inks).
To finish, this link shows you the painting that inspired this colour (also on display at the Rijksmuseum in Amsterdam)
