Ink Bottles - KWZ Iron Gall Ink - Ink Bottles (21 colors)

Iron Gall series by KWZ Ink refers to the type of ink used in medieval times for writing manuscripts, but is designed as modern fountain pen friendly ink. It is gaining popularity because the written notes are extremely long lasting on paper, as the color is darkening over time opposite to some common inks, which tend to fade over years. Writing with it is fun, as the color is changing immediately just in front of you, for example pink is becoming violet or orange is becoming brown. The written notes are also water resistant to some extent. The dyes can be washed away, but iron gall component is permanently bonded with paper, so the text is still easy to read.
The pen filled with IG inks however needs some special care, similar to when any permanent ink is used. It is recommended not to leave it unused for a long time in order not to let the ink dry out in the pen, otherwise it might be difficult to clean the of pen. If IG inks are used on daily basis, there are none special requirements.
The range of Iron Gall KWZ Inks includes 3 types. IG Mandarin is Light Iron Gall - it means that the iron gall component concentration is very low and the maintenance doesn't differ from using standard ink. In the contrary IG Blue-Black is Archive Iron Gall, which means that the concentration of iron gall component is very high, thus it is the most water resistant and the most permanent of the whole IG KWZ Ink range. All the other IG KWZ Inks - blues, greens, violets, reds or brown are the medium type - iron component concentration is high enough to make the notes everlasting, but low enough to be highly convenient in daily use.
