Another Indian Ink

Ingredients

walnut kernels, fruit of the dry pine, myrtle water, vitriol, gum water

Preparation Steps

Original Recipe Text

Take walnut kernels or the fruit of the dry pine, or both together, and place them in a new jar, and let it stay in the oven until it becomes charcoal. It is taken out the next morning and ground for days in a mortar and moistened with myrtle water cooked with something of vitriol according to the aforementioned description. If it is well ground, moisten it with myrtle water and dry it, and moisten it with gum water for every pound of ground charcoal two ounces of gum water. If it is slightly thickened, it will not harm it. If it becomes strong in the mortar, make it into tablets and leave it in the shade, for it will come out well, God the Exalted willing.

Remarks

The text suggests making the ink into tablets and drying it in the shade.
