Rohrer & Klingner Writing Ink - 50 ml Bottle - Eisen-Gallus-Tinte Salix (Iron/Gall Nut-ink Salix Blue)

After researching reviews on this ink, and wanting to write all my letters using a dip pen I bought a bottle. This ink is superb, tolerates amost any type of paper without any feathering or bleed through. It's a joy to write with and the colour is pleasing to the eye.

many thanks,

Colin

I absolutely adore the color of this ink, but I'm worried it might be doing bad things to my pen.

After having the ink in my pen for a few weeks, I've noticed weird crystal things growing on the underside of the feed and nib. If that's going on on the outside of the pen, what might be happening internally? It does seem to be clogging up, and this is a pen that hardly ever clogs. I've never seen crystallization like this from any other ink I've used.

The color, as other reviewers have stated, is really amazing and has the most shading of almost any ink I've used. I would love to continue using it, but at this point I'm too concerned to put it in any pen that cost more than about five dollars.

R&K's "Verdigrease" is an intense, luscious color that flows smoothly and looks great on Clairefontaine paper. It is one of my favorite inks produced by this venerable German ink manufacturer.

I don't favor green inks at all, but this is my ALL TIME FAVORITE. It's a must have. It's like having two inks in one. Each line drawn with this ink has a lot of shading to it. It has character. Simply marvelous.

This is one of the most incredible fountain pen inks ever. Its like having two colors in one -- that's how much shading there is to it. I don't even favor green ink, but this is the best of all inks. I highly recommend it.
