The gallnut is a growth produced on the oak tree by the sting of certain insects and which was used to dye black and to make ink.
Ordinary ink is made with iron salt and gall nuts.
The gallnut has been known in the Mediterranean world since antiquity, it is the staple product of many trades (tanners, dyers, apothecaries) and was therefore traded internationally very early on.
The gallnut is useful in witchcraft to create your own inks as well as for dyeing.
