Exclusive to Cornelissen, our intense black Iron Oak Gall Ink is made to 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 left 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.

Purple Carmine is a beautiful, transparent, blue-purple ink, which can be layered up for deeper shades. This colour can create some interesting effects; when diluted, the purple splits into two colours, a red and blue. Due to the use of cochineal in our formula, this ink is not fully lightfast or vegan.
