Exclusive to Cornelissen, our intense black Iron Oak Gall Ink is inspired by a medieval recipe using oak galls collected in Cambridgeshire. The small, handmade batches are blended to give the required consistency and strength, and are steeped for several weeks and allowed to mature for several more. Lightfast and fully waterproof 5-7 days after application, Oak Gall Ink has been used for centuries by calligraphers and scribes to create illuminated manuscripts and legal documents. When used on animal skins such as vellum, the acids in the Oak Gall Ink react with collagen, effectively ‘etching’ itself into the surface, hence its permanence. As with all products derived from natural ingredients, there may be slight variations in the colour and consistency of the ink due to seasonal changes. Not Suitable for fountain pens.

It has good permanence, but will eventually fade if left in direct sunlight for sustained periods of time, and is not wholly waterproof, but has some staying power, especially on sized watercolour papers. As with all handmade products derived from natural ingredients, there may be slight variations in the colour and consistency as a result of seasonal changes.
