Because the content of Iron Gall component in our inks vary, and been divided into five subgroups:
Light Iron Gall inks (IGL) – those inks have the smallest content of Iron Gall component. These inks have a small water-resistance and they will age only slightly slower in comparison inks based only dyes. Iron Gall component in those inks increase the depth of written text by more increasing both saturation of colour and shading of those inks. In the course of writing a clear change in the color of ink is observed. Light Iron Gall inks are intended to be easy use inks for everyday writing, lower iron content in those inks in comparison to other Iron Gall inks, causes that they do not require such careful maintenance.
Standard Iron Gall Inks (IGS) – inks with similar content of Iron Gall component were formerly used in everyday work and at home. This is a typical all-around ink for daily use when we want both interesting and saturated color and also durability of writing is a matter of concern. Inks of this group are partially resistant to the negative impact of light and demonstrate high water resistance – in the event of wetting Iron Gall component remains intact, and only a portion of dye may wash away, but even after that the text remains fully legible
Targamgall Iron Gall inks (IGT) – Inks of this type have different ratios of components compared to other Iron Gall ink. In terms of the content and type of the Iron Gall component, Targamgall Iron Gall inks stands between Standard, Archival and Synthetic Iron Gall inks. Targamgall Iron Gall inks have similar durability to Archival Iron Gall inks, but text written with those inks will not be as dark. One of greatest advantages of those inks is that they are compatible with greater range of additives and dyes in comparison to more classic Iron Gall inks, granting greater freedom in creating new inks.
Archival Iron Gall inks (IGA) – Inks of this type have very high iron content, much higher than almost all other ‘registar’ type inks which are present on the market. All the inks of this group after drying will have a very dark and deep colour, in most cases after some time period they will be practically black. When I created those inks, durability of written text was my main goal. If you would like to create or run family chronicle this ink is a good choice. Although because of very high Iron Gall component content more care is advised when using this ink, and regular flushing of the pen should be made.
Synthetic Iron Gall inks (IGN) – are not strictly Iron Gall inks in terms of composition, they are rather conceptual development of classic Iron Gall inks, and they share with them similar mechanism of action. Synthetic Iron Gall inks have been developed in the course of work on the improvement of resistance to UV light Iron Gall inks. Because of their nature, Iron Gall inks have a natural tendency to fade due to prolonged exposure to light, by significant change in component this problem was limited.
