Recette: Walnut Ink

Traitement

Pas 1: Boil the walnut hulls in water for one hour and fi lter. First add the iron (II) sulphate and then the potash alum.

Pas 2: After some time, the ink forms small lumps which may be annoying during use. The lumps only settle slowly but will float up again at the slightest movement. It is recommended to filter this ink again.
