I create inks for fountain pens since 2012. It all started when I decided to improve the saturation in one of my inks. During browsing forums and websites I came across various information about self-made iron-gall inks. I found that I should also try and soon after that I prepared my first iron-gall ink. Over time, I began to enrich inks I prepared with interesting colors, and tuned ink’s properties.

Creating inks is a great hobby. The possibility of creating ink of almost any color and setting properties of such ink according to my discretion gives a lot of satisfaction. Making new inks is not always easy, sometimes many attempts have to be made before specific color or property is achieved. There were many hard moments when well thought out formula didn’t give expected result or it came out as unstable and ink quickly degraded. But overall ink making is occupation that gives us plenty of satisfaction.

Production of inks on a large scale is not my goal, but instead we will focus on creating inks a little less common, something which can not be found elsewhere. I create my inks from scratch, by mixing raw chemicals which as a result give fountain pen ink. To ensure myself a bit of comfort during and increase repeatability in production of inks  I introduced number of improvements to my lab, but most of the work in the production of inks is still done by hand.

For a long time I have created inks were not widely available and the information about them were scattered on various websites and forums. I set up this site to gather information about KWZ Ink in one place and facilitate communication with me, so that my inks and information about them will be readily available.


  1. Matt (The Pen Habit) send me here !! please make the IG inks available world wide ( through your own website ).

  2. I am delighted that you are make a special ink for the Toronto Scriptus show.

    As a custom maker of inks, have you considered replicating Flo-master inks. These were popular because they were opaque and brilliant. Apparently, the indigence include too much lead. They also floated in a water bath, thereby allowing amazing marbling affects, like Victorian end pages. I guess that the dye is oil soluble and combines with the water elements using an alcohol molecule. These are the ingredients found in perfume so there should be a great deal of supporting data. The opacity might be increased with titanium oxide.
