I am currently working on some stuff from the Grimorium Verum, and I am very keen to try the experiment "To See Spirits of the Air", but I am not about to go slay a cock and dig up dirt that has touched the coffin of a dead man. Are there any good substitutes?
The walnut oil on the other hand seems managable, but I am not sure how important it is for both the paper and the wax to be "virgin". Would it be enough for them to be unused?
