Iron Gallus ink
Iron gall inks have been in use since the 3rd century AD.
They consist of iron and copper sulfate, tannins from gall apples, gum arabic, and wine or water as a solvent. Writing made from iron gall ink is gray at first, but then turns black. Unfortunately, iron gall ink attacks the parchment after some time (ink corrosion).
Take gall apples from the oak and gum arabic, two ounces of each, plus three ounces of vitriol. Crush the gall apples and soak them for three days.
Then boil them in three quarts of rainwater or in water from a standing basin. When half the water has evaporated, take them off the fire and add vitriol and the gum arabic, stirring everything until it is cold. Then put it in a cold, damp place. Note that it goes bad after three weeks.

Octopus Write & Draw Ink, waterproof ink for fountain pen, nib and brush, vegan
The Octopus Write & Draw inks are unique, smudge-proof and waterproof writing and drawing inks in a wide range of colours. They were developed for daily use in fountain pens and are also popular with graphic artists, illustrators, calligraphers and artists for writing, sketching, drawing and colouring with calligraphy pens, glass pens or brushes.
Each of the 38 brilliant shades inspires with its intense colour power thanks to its high, balanced pigmentation. In addition to a deep black and various shades of grey, the extensive colour palette also includes a particularly opaque white, which can be used on dark backgrounds.
During the development of the drawing ink, special attention was paid to its use in the fountain pen. The use of the finest colour pigments in a carefully balanced formula ensures high light fastness and a good, even ink flow without clogging the ink duct of the fountain pen. These pigmented writing inks also feature the excellent writing behaviour of the classic Octopus fountain pen inks. The Write & Draw drawing ink meets the requirements for document-proof ink according to DIN ISO 12757-2 and DIN ISO 14145-2 and is produced exclusively with vegan ingredients.
Writing enthusiasts love the razor-sharp typeface that can be achieved on fountain pen-suitable paper and the pleasant shading of the Write & Draw writing ink. Calligraphers can create the finest hairlines and impressive flourishing elements, while urban sketchers can draw precise outlines.
The ink dries waterproof in a very short time and can then be painted over with another shade of Octopus Write & Draw ink or watercolour. It is eraser-proof and most of the colours are also highlighter-proof.
Both pure and diluted with water, Octopus Write & Draw ink is excellent for colouring. Used undiluted, the waterproof ink convinces with its opacity. The many colours of Octopus drawing ink can be mixed with each other, but also with water. In this way, countless colour shades can be achieved for beautiful watercolour effects.
Unlike most other waterproof inks, Octopus Write & Draw can be used in a fountain pen without hesitation. However, care should be taken not to let the fountain pen dry out. The water resistance of Write & Draw Inks is created with the help of a cross-linking binder, which cannot be easily dissolved when dry. We therefore recommend that you rinse and clean your writing instrument carefully after use to prevent the ink from drying up accidentally.
The Octopus special cleaner for pigmented inks is available for cleaning your writing Instruments.
