🧾 Description

Tintenlabor is a Swiss ink company specializing in Iron Gall inks. What differentiates this brand from others is that it discloses the iron content.

The samples were sent to me by David, the Ink-Meister.

Dark Green 1 has 3 g/L iron content and high dye content. It is the most user-friendly of the original Dark Green series.

Writing with these inks is different, especially for the modern user who is used to well-lubricated inks. The more I use these inks, the more I cannot get enough of them. It is a bit like tasting wine or dark chocolate: either you are hooked or not.

Dark Green 1 had flow issues with the Sailor Fude de Mannen, yet it worked well with a Chinese fude pen. It needs a wet pen and benefits from soft nibs and well-sealed pens.

The colour is a lovely, mysterious green-grey iron gall shade with the lowest oxidation of the group, depending on how much ink you put on the paper.

The ink also benefits from being left in the pen overnight; for some reason, the flow regulates itself.

Cleaning was effortless with most pens, but more time-consuming with vintage pens.

Cleaning Note: Like all IG inks, flush with water first. For stubborn residue, use a small pinch of pure ascorbic acid in water, then rinse thoroughly. Avoid ammonia-based cleaners with iron gall inks.

An ultrasonic cleaner can help with removable pen-safe parts, but avoid it with fragile vintage materials, plated trim, or anything uncertain.

💧 Water Test

Bottom side: 10 seconds under running water, after 24 hours.

Note: I named the ink by its iron content on the page. It should read Dark Green 1, not 3. You can also see how intense the oxidation is when ink is applied liberally with a glass pen.
