This is the fifth Heritage in Schools tutorial of the week with thanks to the Heritage Council presented by Heritage in Schools Specialist Maura Brennan.

Early manuscripts such as the Book of Kells were created using Oak Gall Ink. In this tutorial we learn how Oak Gall Ink is made. Oak Gall wasps lay their eggs in Oak trees, The Oak tree responds by forming a gall around the larvae.

The Oak galls are full of tannins and it is the tannins that are the essential ingredient to making Oak Gall Ink. Maura also shares a simplified recipe which can be made from household vinegar and ideas on how to make other plant based inks such as turmeric , elderberries and blackberries.

Materials: Vinegar, a jar, Oak galls, plant materials to experiment with such as blackberries, elderberries, etc; paper, paintbrush/feather/ stick for mark making.
